Weekly Wrap: This Week In Chainlink September 20 - September 27

Announcements and Integrations 🎉

Decentralized VPN network @OrchidProtocol launched an additional Chainlink oracle live on mainnet to aggregate bandwidth pricing from Orchid providers. This allows users to easily estimate the cost of network services, ensuring they pay a fair market price.

Given their successful testnet implementation of the Chainlink-powered ELA/USD price feed, blockchain platform @ElastosInfo integrates additional Chainlink price feeds on its ETH sidechain to power an upcoming money market dApp.

Cross-chain DeFi platform @ReefDeFi will use Chainlink's ETH and DOT denominated Price Reference Data to power their smart asset management tools, such as automated portfolio rebalancing and yield farm optimization based on changes in asset prices.

DeFi-powered NFT project @aavegotchi is integrating Chainlink VRF as its source of provably fair randomness. Chainlink VRF will help determine an Aavegotchi’s unique characteristics, generate unpredictable game scenarios, randomly select DAO jurors & more.

@Theta_Network & Chainlink collaborate to solve click fraud w/ universally connected smart contracts. Proving user activity wasn't adversarial bots prevent theft of funds & correctly sends payments for better content to publishers that deserve to be paid.

We're excited to help support the larger blockchain community's open-source development by contributing financial resources to @gitcoin's Grants Round #7. Chainlink strongly believes in supporting the open-source ecosystem that we are all building together.

2020.09.01 20:55 Glittering-Story4190 How likely am I to get fired?

I work on the IT advisory/audit side. Been in position for over 1 year.
I sent some access testing to the client to have them review for appropriateness, they noted a couple termed users, come to find out I accidentally copy/pasted the old testing matrix data into the current one. Every other system I did the work for, but this one just slipped through the cracks and now is blowing up in my face.
I've been having to this project by myself with no other associates, and my senior is giving me no help. Only reviewing my work, and leaving comments. I've worked long hours past couple weeks and not charged the time because I keep getting told we're over budget compared to last year. It's not a good excuse, but it's the way things are.
Client was mad and reached out to the manager, and I'm having to go back and double check my work. Senior has been riding me this entire project about getting stuff done, when I have no help. This is the final week so not the best way to leave a project.
I know I royally F-ed up. And my performance reviews have been inconsistent. Some say I'm good, other's average, one below average. How likely is this to get me fired?

ETA:
Problem got worse.
Either from my lack of sleep over the past few weeks, or my senior constantly asking me for something, I learned my accidentally carried over 3 systems from prior year, and not just 1. And I can't remember if I did it because my senior kept demanding something and I did it to just give something, or because the PBC's were absolute trash.
At this point, I'll be surprised if I last till Friday.

2020.08.12 13:21 smackmybutt (WEBCOMIC SPOILERS) Crackpot theory: Metal Knight, Drive Knight and Genos

This theory goes over all three's relations with each other and the Organisation. I think that what Drive Knight (DK) told Genos about Metal Knight (MK) was true but DK was not trying to frame MK in any way (yes he does try to frame MK later on with Senkingar, but with Genos I believe that was not the primary goal). Genos' background is definitely questionable, in terms of what town he came from and the events of the Mad Cyborg. My headcannon is that Genos IS the Mad Cyborg but went through some sort of memory erasing process (by Dr.Kuseno?) possibly to remove any form of guilt from his mind for going out of control and killing many. I also believe that the Mad Cyborg is a creation made by the Organisation that went rogue (after his memory got erased). It's possible that MK has checked Genos' past using his registration and background information through the hero association database (just like CE did) and found it extremely suspicious. Based on this, MK has a sneaking suspicion that Genos is also the Mad Cyborg that may be hiding undercover, either into hiding or maybe even spying on the HA for the Organisation.

DK must've heard about MK's suspicion and came to inform Genos, but not in the form of kindness. I believe that DK is part of the organisation and also knows about Genos' past and, in a multi-step sequence of attempts, is trying to convince Genos to side with the Organisation.

MK is an enemy to the Organisation. There are not many pieces of evidence to back this up, other than G5 attempting to collect data from MK's suit of armour and his rants about how the world is about to get fucked when it's weakened, hinting to the Organisation. I believe DK is a part of the Organisation for many reasons, like how he mysteriously disappears to collect data on different monsters just like how G5 does with heroes or how he tries to frame MK (since he is an enemy) to being a traitor in order for the HA higher ups to lose their trust in him and leaving him with less power as he has less influence over the HA. Another piece of evidence is DK's obsession with Blast, almost as if he wants to see Blast fight and collect battle data on him, just like G4 tried doing with King. Going back to framing MK, DK makes up hypothetical scenarios of the HA being overwhelmed and attacked by the Monster Association through MK's military technology when they are weakened when in reality that could be the Organisation's ultimate plan to destroy the HA. Heck, even DK's design is similar to that of the Machine God series, all of them having a single eye with a sort of triangular face (well except for Machine God Mirror, but he seems to be some sort of exception or special case to the rest of the Machine God series as he doesn't even have a number designated to him). Even this guy on the right has a single eye and you can sort of make out a triangular shape from his facial structure where the jaws and chin join together.

I believe this is all linked to what's happening in the Webcomic currently. As 4 Dragon level monsters suddenly appeared, quite a few S-class heroes have left the HA, the HA's status and reputation is definitely not in a good state, HA has mainly lost their trust in MK and his defenses that are supposed to protect the HA Headquarters and the Neo heroes rise in power, they took this advantage to release Machine God Mirror, another Dragon level threat, in order to overwhelm the HA even more and deprive them of their main forces AND to finally collect battle data on King with no distractions or heroes interfering like Genos did last time (at least that's what they had planned before Suiko came along. However, they didn't really take her into consideration since she was a new hero and didn't even know who she was), therefore making the hypothetical situation that DK warned Sekingar about into a reality.

Thanks for tuning in, please feel free to give opinions and any inconsistencies/plotholes in my theory which I'm sure there are!

2020.07.13 11:56 OHH_HE_HURT_HIM 1st game of 9th. Death Guard are looking good

So I had my first game of 9th last week with the Death Guard. I did better in that game than I ever did in 8th.
Quick overview:
Mission: Data Retrieval
Secondaries:
Army:
Opponent:
Secondaries:
Army Blood angels:
So generally I just needed to stay alive and control the board to win while my opponent needed to cover the board while also killing as much as my stuff as possible, especially the daemon engines.
I was able to win by just holding onto more objectives and keeping my big things alive.
Some key take aways:
Over all I think the biggest change in 9th for Death Guard is the inclusion of secondaries and the change in focus for primary objectives. Previous missions in 8th (and basically warhammer as game as long as i remembered) Always encouraged fast armies that could things quickly. You needed to touch an objective to get a point, kill an enemy unit completely in one go to get a point etc. This is why armies like Eldar have always been at the top. Their whole theme suits the game perfectly. Death Guard are designed to be a slow grinding army and that just didnt fit into the way 40k missions worked. You can now tailor your objectives to play that way. You dont need to try and only take demons engines and flying princes to be quick, you dont need to bring a chaos souped in gunline to farm kills early on. You can actually play like the trench fighter plague marine whos dug in and just wont shift.
Looking forward to having more games soon. Thinks are looking up for Death Guard!

2020.07.06 19:37 MathigNihilcehk Arknights Priority Planner 3 Supply Missions no longer optimal

If you've been following along with this planner, skip to the Current Updates below.
If you enjoy planning out your operator upgrades, this is the best tool for you. While there are other tools that can calculate a resource requirement, this one can:
Want to use this tool for yourself? Just download the file here.
Important note: You need to use Excel or LibreOffice Calc, otherwise the macros used to calculate mission counts will not be available on google sheets. Everything else should work in google sheets. You'll just have to manually adjust the number of missions until the optimization number reaches 0.
Exceptions: Does not include Resource Search, Event Maps or CN maps.
CURRENT UPDATES
You may be wondering why I decided to roll out an update so soon after the last one. Well, sadly, the last version was plagued with errors and bugs that took some time to iron out. There are so many changes it didn't make sense to call it a minor update anymore.
Quick note that my optimal stages for tiers 1 to 3 are subjective based on how you define them. Tier 4 stages are definitely the optimal long-term stages, but you can define any number of mid-term conditions. And just a reminder, if you want to change which stages you optimize for, you can easily do that. See the video in the following paragraph around 6:13.
My tutorial for the planner is here. The interface has changed slightly, but it can be used exactly the same way.
Libre Office Caveats:
First you have to enable macros. Tools => Options => Libre Office/Security => Macro Security => Medium or Low should work.
I don't think the button will ever work so you need to run the optimization manually. Make sure you're on the Control Panel, then go to Tools => Macros => Run Macro => Expand Arknights Priority Planner => VBAProject => Module1 (click it) => Optimize => Run => if you're sensitive to flashing lights avoid looking at your screen for a minute or two as your mouse freaks out and spasms for a minute while the program runs.
Special thanks to elmoe0715 , zhouster , enki1337 , PeterYR , Dampdrooid , inftotality , and neetchanathip for suggestions and feedback.
Source for Drop Rates: Penguin Statistics' site.
Source for Operator Upgrade Costs: Manually copied from GamePress's site.
Let me know if you find any bugs, have any feature suggestions, or if you would like to ask any questions about this program. Enjoy!
Version History: We're labeling version now! This is the big 3.0!
Added a version that is set up to farm only the optimal maps for tier 4 for tiers 3 and 4, as opposed to the mid-way optimal maps selected normally.
Version 3.1 is now out.
Issues with 3.1.

2020.06.26 02:30 DuncnIdahosBandurria Altus Property Ventures goes live TODAY; Wildcard guy in China? (Friday, June 26)

Happy Friday, Barkada --

The PSE closed down 71 points to 6119 ▼1.14%.

Daily meme

COVID Update

WW: 9520818 PH: 32295 

Top 3 MB indices:

 Power Gen. ▲1.42% #COVID-19 ▲0.54% POGO Prop. ▲0.23% 

Bottom 3 MB indices:

 Cement ▼2.68% 2019 IPOs ▼2.26% MiddleClass ▼2.00% 

Main stories covered:

  1. [UPDATE] Atlus Property Ventures [AVPI P10.10]: The weirdest little non-IPO goes live today… as discussed in previous days, Robinsons Land &RLC is “birthing” onto the PSE a wholly-owned property development subsidiary called Atlus Property Ventures. For reasons that are more technical than practical, RLC was able to bring AVPI to the market without going through the traditional “IPO” route, which would have involved getting an underwriter, and then that underwriter building a book of potential buyers, and then offering that stock to investors, and then finally doing a glitzy initial public offering on the PSE. Instead, RLC just “dividends” (or “airdrops”, for my crypo fam) to every RLC shareholder one (1) AVPI share for every 51.something (51.x) RLC shares owned by the shareholder.
MB: If you plan to trade this stock today, just remember that the PSE’s usual price flooceiling limits may not apply, due to how the stock is hitting the market (as an “introduction”, and not an “IPO”). This is not unprecedented, but it is rather uncommon, so…. be careful!
  1. [UPDATE] Wirecard: So looks like the ex-COO was here in June, as well… the Department of Justice, the parent agency of the Bureau of Immigration, indicated that its records show that Wirecard’s ex-COO Jan Marsalek was actually in the Philippines for one day in June, arriving on June 23, and leaving the next day for China through Cebu.
MB: The DOJ said that Marsalek is married to a Filipina, and that may be why he was able to enter and leave the country despite the COVID-related travel restrictions.
  1. Liberty Flour Mills [LFM 41.00 ▲2.50%] Q1 net income up 400% y/y… the company made a P21-million profit in Q1, which was a “very huge increase” and “significant turnaround” (LFM’s words, not mine) from the P7m loss that it posted in the same period last year. LFM noted that it sold 103% more bags of flour in Q1/20 than in Q1/19, leading to 88% more revenue with only a 69% increase in the cost of sales. Nice.
MB: The domestic flour market had been growing at a fairly decent clip, as was noted in January (pre-COVID). But the real magic for LFM was what happened to flour demand after COVID, especially in the early throes of the NCR and Luzon lockdowns, where food supply sufficiency was not a settled question. Many families (mine included) took to baking to supplement non-perishable food supplies in preparation of the “OMG what if” scenarios that we all talked about in those days. I can’t be the only one who experimented (deliciously, I might add) with making my own bread!
  1. DITO CME [DITO 3.44 ▼4.44%] FY19 net income down 400% y/y… the company, the remnants of what used to be ISM Communications Corp, which itself was the remnants of what used to be IItogon-Suyoc Mines, Inc. (hence the “ISM” part), was transformed by Dennis Uy into DITO CME Holdings Corp in 2016. The stock’s ticker only very recently changed from “ISM” to “DITO”, though it’s worth noting that “DITO” refers to DITO CME, the holding company, and not to Dito Telecommunity, the nation’s 3rd telco that is a subsidiary of Chelsea Logistics [C 3.65 ▼4.20%], which itself is a subsidiary of the private Udenna Corp, owned by Dennis Uy. Basically, this company, DITO CME, is “DITO” in name only. As the financial statements say, and as DITO itself will tell you, “DITO currently has no operating business”, and what business it does as a holding company is rather limited just yet. Still, DITO lost P35-million in 2019, as compared to the P7-million that it lost in 2018.
MB: As a general rule right now, I’m pretty much writing off all the annual reports. Anything pre-COVID is almost useless. The most important data right now is found in Q1, so the quarterly reports, but even inside those quarterly reports, the most important information is the pre-lockdown performance vs the post-lockdown performance. Most companies did not provide a great breakdown of that, though some did, so we will all need to wait for Q2 to come out for a better comparison. It was interesting, though, to realize that DITO owns a 13.33% stake in the Philippine Bank of Communications [PBC 19.00 unch], which actually started out as a 36.64% stake acquired by the company (then, ISM) in 2011. ISM cum DITO’s stake in PBCOM was diluted twice in three years, and has stood at 13.33% since 2014.

2020.06.24 01:44 Preyy Memmove8 with XY mapping

Hi everyone, I'm looking to use memmove8 to make a cascade, where LED data moves down rows. Unsurprisingly however, the memmove8 function does not work when the LEDs are wired from the top in vertical rows. Is there a workaround for this? I could just use:
 for(int y = LEDper-1; y > 0; y--){ for(int x = 0; x < LEDstrips; x++){ leds[XY(x,y)] = leds[XY(x,y-1)]; } } for ( int i = 0; i < LEDstrips; i++){ leds[XY(i, 0)] = CHSV(0,0,0); } leds[XY(random8(LEDstrips), 0)] = CHSV(random8(), 255, 255); FastLED.show(); 
but I was wondering if there is a better way. Thanks for considering this!

2020.05.14 20:06 grrmachine49 JLC2313 stackup with DDR3 fly-by

JLC2313 stackup with DDR3 fly-by
Hi everyone,
I’m building a simple SBC based on Allwinner A33 for my undergraduate final project, includes two x8 DDR3 chips. I’m going with 6 layers JLC2313 Stackup 1.2mm thickness (cost reasons). It’s my first DDR3 design and I have a lot of questions.
Their website/field solver suggests 14 mil track on stripline and 5.7 mils on microstrip for SE50 ohms impedance. That’s super thick.
  • I was wondering if I can use SE60 ohms and 120 ohms for differential pairs on DDR3 (That’ll be 9.4/3.8 mils).
  • I’ve included the stack up. L1=> Signal, L2=> GND plane, L3=> Signal, L4=> Signal, L5=> Split Power, L6=> Signal. The prepreg (Dk=4.25) between L3 and L4 is just 5 mil (0.127mm) in thickness. Would that cause a lot of crosstalk? Was planning route ACC on L3 and data banks on L4. Would keeping almost minimum intersection help me out here? I will reference it to the adjacent layers (GND,VDDQ) , separated by cores with a thickness of 14.37 mil (0.365mm).
  • Any suggestion on ddr3 layout and layer utilization, especially with JLCPCB’s 6L stack up? (Included a preliminary component placement).
  • About DDR3 termination, BBB, most of the boards from Bpi, Olimex, OrangePi and even Rpi seems to be termination only the DRAM clock. What about ACC group?
  • DRAM reset signal, Is it a pull-up or down? Is it SoC specific? DRAM_RESET is active low, but I've seen a couple other designs utilizing a pull down. I’m using H5TC4G83AFR-PBA/PBC DRAM chips.
  • I understand differential pair’s impedance can be seen as two single ended TL’s impedance coupled with a gap. I’ve tried iCD stackup planner and can’t quite get the bang-on 120 ohms differential geometry right on JLC’s stackup (aware of the 10% tolerance), same story with their website (they seem to be using Si8000). So, is it weird to maintain 60Ohm SE and 100Ohm Differential for DDR3 signals?
I highly appreciate any inputs and suggestions. Thanks a lot

2020.04.28 23:46 Anurag_Mohanty HTML AND CSS

I am doing a HTML & CSS course in Pirple.com. As a part of task I'm gonna share the things I have learned so far.
I was given a task to create a webpage about my favourite book with different HTML tags.
I have written the code with different HTML codes like , ,



The Alchemist said:

“And, when you want something, all the universe conspires in
helping you to achieve it.”





THE ALCHEMIST-“So, I love you because the entire universe conspired to help me find you.”




ALCHEMIST SUMMARY
The Alchemist is a novel by Paulo Coelho in which Spanish shepherd Santiago
dreams of a long-buried treasure in Egypt. He sets out on a quest to obtain the
treasure.

  • After experiencing a prophetic dream, Santiago travels to Africa in the hopes of finding treasure buried beneath the pyramids.

  • Santiago meets an alchemist, who agrees to take Santiago to the treasure.

  • Santiago reaches the pyramids, but there is no treasure to be found.

  • A group of war refugees attack Santiago, and one of them mockingly mentions a dream he had about a treasure buried beneath a Spanish church. Santiago returns home and unearths the treasure.

2020.04.24 08:38 insanesniper80 Motorola G5 Plus with DJI Fly App - SOLUTION!

Hi guys,
Like many of you, I was also pretty annoyed to find my MORE than capable Motorola G5 Plus to not allow the download and running of the DJI Fly app from the Google Play store, of course this was AFTER I received my Mavic Mini.
The issue is, although the Motorola G5 Plus IS in-fact a 64bit processor, Motorola designed the factory ROM in 32bit. And THAT is the problem, the DJI Fly app sees a 32bit operating system and says 'NOPE!'.
Well, not a problem any more if you have a little bit of technical ability.
All modern day Android ROM's are built on 64bit, meaning you simply need to install a 64bit ROM to suit your device and the app will be available to install and run as intended.
I personally had success with the Motorola G5 Plus (XT1685), by flashing a 64bit ROM called Pixel Experience which installs Android 10 and allows DJI Fly app to be installed from the standard Google Play app.
Basically it turns your Motorola G5 Plus into a Google Pixel with 64bit software to suit our 64bit hardware, with all the features of Android 10.
This involves the following: 1. Unlocking the MotoG5 boot loader (This is supported by Motorola and they provide all required information on their website to do this).
  1. Installing TWRP Recovery Console on the device
    1. Flashing/Installing the Pixel Experience ROM that suits your device.
***FIRSTLY, and ultimately, I am not responsible for any failures you may have, (although would be extremely rare), but I'm MORE than happy to help with questions etc.***
*YOU SHOULD make a BACKUP of all your phone data, files, photos, etc, as the procedure will effectively wipe all personal data.
*YOU MUST ensure all ROM/flashing files are for YOUR specific device. *YOU MUST follow ALL instructions that you find by the developers and the XDA forum. *ALL of the above tools required are FREE and most information can be found via a simple google search and XDA forums.
The entire process shouldnt take more than 1 hour to acheive, it is really quite easy and the result is worth every second it takes you.
Flew my Mavic Mini thismorning using my Moto G5 Plus with the new Android 10 Pixel Experience, and it was faultless!
Any questions, I'm happy to help! 📷

2020.04.08 13:50 Ausernamenamename Facial recognition law passes state senate and Gov Inslee signed into law Mar 31st. WA state.

Yang Gang! I'm asking for help from anyone living in WA state right now. Hell I think everyone should contact their representatives now and tell them you don't want to live in this kind of authoritarian nightmare.
On March 31st, during the middle of a pandemic our state Senate and Gov Inslee signed into law a bill that grants local and state authorities the power to use facial recognition to monitor it's citizens. If you live in Washington oppose this kind of legislation I need a moment of your time to contact your representatives and let them know you oppose:
ENGROSSED SUBSTITUTE SENATE BILL 6280
Sec. 1. The legislature finds that: 6 (1) Unconstrained use of facial recognition services by state and 7 local government agencies poses broad social ramifications that 8 should be considered and addressed. Accordingly, legislation is 9 required to establish safeguards that will allow state and local 10 government agencies to use facial recognition services in a manner 11 that benefits society while prohibiting uses that threaten our 12 democratic freedoms and put our civil liberties at risk. 13 (2) However, state and local government agencies may use facial 14 recognition services to locate or identify missing persons, and 15 identify deceased persons, including missing or murdered indigenous 16 women, subjects of Amber alerts and silver alerts, and other possible 17 crime victims, for the purposes of keeping the public safe.
They penned a bill in the middle of a pandemic to strip us of our freedom and allow local and state government to use facial recognition to track us. Luckily time is still on our side as it won't be in effect until 07/2021. But I need your help now. If you live in Washington you can enter your details on and leave a comment directly opposing this bill here. This will reach your representatives directly. Thankfully I received a response from my city official within minutes letting me know that they opposed this bill but need votes to repeal the law.
This is not a joke. This just happened here, it will happen where you live too. Yang said your Data belongs to you, shouldn't that include your biometric data? A bill like this should not be passed without a vote from the people under the cover of complete media darkness.

2020.04.01 00:43 yelram87 Socket for connecting PCBs

I‘m currently looking for a way of connecting two PCBs.
What I currently have in mind is to integrate the male connector directly into the copper part of the design. The other PBC would then have a socket soldered onto it, where PCB 1 can be plugged in. Basically the way it works with expansion cards for computers.
How are those sockets called? I would actually only need 5-6 data lines on one side of the PCB, so the old PCI/ISA type slots would be way too big.
Any better ideas maybe?
Thank you!

How're the Properties of PCB Material

A MUST READ: PCB MATERIAL GUIDE

https://preview.redd.it/dur4hvc9irl41.jpg?width=828&format=pjpg&auto=webp&s=8c50888a9a1b49ab75270e3541d041a84cf21760
Before we talk about PCB material, let’s started with a PCB introduction.PCB is a self-contained component of interconnected units found in gadgets ranging from ordinary beepers or pagers to complex radar and computer programs. A thin layer conducting substance printed or deposited on the insulating board called the substrate is used to develop circuits. The specific electronic units are put on the substrate’s surface, which is then soldered to the interlocked circuits. It is common to have PCB performing one role, for instance, a signal amplifier or a number of functions. There are main types of PCB construction. These include:
  • Single-sided PCB
  • Double-Sided
  • Multi-layered
PCB is the most critical part component of electronics. You may have heard of the printed writing cards or printed writing board when individuals talk about PCB. Well, there is no difference between these terms; they mean the same thing. Due to their significance in all electronics, including computers and calculators, the board material for the PC is chosen with a lot of care and caution. The person making the selection must have knowledge of the electrical requirements of any type of equipment.
Prior to the establishment of PCB, the materials used for early boards were often covered by shells of knotted overlapping wirers, which could fail at particular junctures. When used for relatively long, they could as well short circuit, and some wires could start cracking. Expectedly, the manual process used in making these boards was so demanding, confusing, and meticulous.
Since many electronics started depending on circuit boards, it became increasingly necessary to come up with modest, more compact options, and this is precisely what led to the emergence of PCB material. Importantly, the metal, which enhances the flow of current between the board and the components attached, is referred to as solder. This substance has dual roles considering its adhesive features. This blog covers all the details you need to know about PCB materials. So read to the end, and you will enrich your knowledge and perhaps make the right choice when required.

The Basic Properties of PCB Material

This is perhaps the most crucial aspect you need to pay attention to. As we mentioned at the outset, you need to be careful while selecting the PCB material, and being acquainted with the properties is so crucial. In this section, we are going to look at thermal, electrical, and chemical properties. So let us begin

Thermal Properties

As the title suggests here, we examiner the effect of temperature. Pay attention to the following.
  • The Glass Transition temperature**. Temperature ranges affect PCB material significantly. Generally, the substrate softens if subjected to a temperature beyond the required threshold. But again, the substrate will harden when taken back or when the temperature is readjusted to normal. The range where transformation can possibly occur is called glass transition temperature (Tg). This unit is determined in degrees celsius.**
  • The Decomposition temperature**. This is a temperature within which decomposition of the PCB material takes place. Generally, when the substrate is in temperature beyond a particular threshold, it decomposes. Unlike in glass transformation, the effects of substrate decomposition are irreversible. Why does this imply? People work in different environments with different temperature ranges. When selecting a PCB substrate, you need to ensure it is really compatible with your working environment.**
  • Coefficient of Thermal Expansion**. The expansion rate of any PCB substrate is the CTE. Whenever a material his subjected to a temperature beyond its Tg, the CTE rises, and this is quantified in parts per million (ppm). A PCB material often has a greater CTE compared to a copper layer. In most cases, this deviation in temperature is the leading problem of interconnection issues when heated. However, because of the constraints in the PCB material as a result of the glass woven, CTE is generally within 10 to 20 ppm in the X and Y axes. In case the temperature goes beyond the Tg limit, the CTE does not change.**
  • Thermal conductivity**. The heat conductive characteristics of PCB material is called thermal conductivity (k). The thermal conductivity of a substance is directly related to the potential of a PCB material to transfer heat. The thermal conductivity is determined in in watts per meter (w/m), expressed in kelvin (k)**
In light of the above, the thermal properties of a PCB substrate is a vital factor for consideration. PCB materials are significantly affected by temperature ranges, and so you should pay attention to the conditions in your working environment. What about the electrical properties?

Electrical Properties of PCB material

There are several electrical characteristics you need to consider when it comes to the choice of a PCB material. The following is a brief overview of some of them.
  • Dielectric constant**. This feature is Relative Permittivity. Impedance and integrity are the two most significant factors for consideration when it comes to the electrical performance of a PCB substrate. The dielectric constant of a PCB material range from 3.3 to 5.5. This value is affected by frequency. Specifically, it is inversely related to the frequencies. Nevertheless, Er changes differently in different materials. It changes less in others and more in others. For a substrate to be safer for use in high-frequency applications, it should have a stable dielectric constant in wide frequency ranges.**
  • Dielectric Loss Tangent (Tan δ). It is also the Dissipation Factor (Df). If a material has a low loss tangent, it actually loses less power. The loss tangent applied in the PCB materials often varies from 0.02 to o.oo1. The higher value applies to most of the materials, while the latter one is used in the high-end materials. Besides, the loss tangent is also affected by the frequencies. It increases with a rise in frequencies. However, on the basis of digital circuitry, the loss tangent is not very significant.
  • Volume Resistivity (ρ). This is the resistance of any dielectric substance to insulation or perhaps electricity. If a PCB substrate has a great resistivity, it is not likely to expedite electric charges. The resistivity of any dielectric substance is measured in ohm-meters (Ω-m) or ohm-centimeters (Ω-cm). Just like in the dielectric insulators, all the materials on the PCB needs to have high resistivity. The preferred resistivity value range between 103 and 1010 Megaohm-centimeters. Nevertheless, external factors such as significant temperature variations and humidity influence the resistivity of a substance.
  • Surface Resistivity (ρS). This is the surface resistance of a dielectric substance to insulation as well as electricity. Just like the volume resistivity of a material, surface resistivity needs to be high. It should range between 103 and 109 megaohms per square. Also, differences in temperature and moisture influence surface resistivity.
  • Electrical Strength**. Throughout the Z direction of a PCB substrate, the potential of a dielectric substance to withstand electrical breakthrough is called electrical strength. This is determined in volts/mil. Most PCB substrate’s electrical strength falls between 800 V/mil and 1500 V/mil.**
Indisputably, the electrical characteristics of a PCB material is a vital factor for consideration. From the above discussion, it is crucial to pay attention to these properties when making your choices. Let us now look at other aspects of PCB material properties.

Chemical Properties

The following are the critical properties for consideration in this regard.
  • Flammability Specs (UL94)
  • Moisture Absorption**. This is the capacity of a dielectric substance to resist exposure to a liquid. The moisture absorption figure for many PCB materials ranges from 0.01% to 0.2%. In general, moisture absorption affects both the electrical and thermal characteristics of dielectrics.**
  • Methylene Chloride Resistance (MCR). This is the chemical resistance of any PCB substance. This measures the dielectric strength of methylene chloride absorption. The MCR often ranges from 0.01% to 0.20%.

Types of PCBs

As we stated at the outset, there are three main variants of PCB materials. Let us now review them in detail.

Single-layer PCBs

As the name suggests, this is a PCB made from one layer of the base substance. Usually, a tinny metal layer covers one side of the base substrate. Since copper is the most fantastic electrical conductor, it is always preferred as a coating. Upon applying the copper base platting, a protective solder mask is often applied. Finally, the last silk-screen is used to mark out all the essential units on the board.
Single-layer PCBs are quite easy to create and manufacture. This is due to the fact that they have different circuits and units soldered on a single side. For this reason, single layer PCBs can be acquired at relatively lower prices, especially where one makes a large volume purchase. They are used for different applications such as calculators, printers, and power supplies, among others.

Double layer PBCs

Unlike single-layer PBCs, double layer PBCs are characterized by base material having a slim layer of a conductor, such as copper on both sides. Holes are often drilled on the board to enable circuits on one section of the board to link to the circuits on the end.
In the double layer PCB board, the circuit and the components are often linked in two ways. The first one can be using a through-hole and a second one utilizing a surface-mount. In general, a through-hole connection simply means the minor wires, also referred to as leads are always fed via the holes. Afterward, the leads are soldered to the appropriate component.
In contrast, the wires are not used in the surface mount as connectors. In this case, a lot of soldered small leads are directly linked to the board. This implies that the board itself is a wiring surface for various components. This permits the completion of the circuit with limited space. A lot of space is freed, and as a result, the board can carry out more functions at a faster speed and a lightweight compared to when through-board holes are used.
Usually, double layer PCBs are utilized in the applications demanding an intermediate degree of circuit complexity, including the following:
  • Industrial controls
  • Power supplies
  • Instrumentations
  • LED lighting
  • Automotive dashboards
  • Amplifiers
  • Vending machines

Multilayer PCBs

Multilayer PBC is made up of a series of either triple or a number of double-layered PBCs. A specialized glue is often used to secure these layers before they are sandwiched between insulation units to make sure too much heat cannot melt or soften any of the individual components. Additionally, these PBCs are always in a variety of sizes. They can contain only four layers, or as many as ten or twelve. The biggest multilayer PBC ever to be designed was 50 layers in thickness.
If a PBC has a lot of layers, developers can come up with quite thick, complex structure appropriate for a wide range of intricate electrical functions. Multi-layer PBCs can be pivotal in the following applications:
  • File servers
  • Data storage
  • GPS technology
  • Satellite systems
  • Weather analysis
  • Medical equipment

The Common types of PCB Materials

There are three common materials crucial in the fabrication of the PBCs. The following is a brief overview of each of the three.

FR-4

This is the widely used material in the manufacture of PBCs. It is just a glass strengthened epoxy laminate sheet. The laminate that is utilized here flame retardant and also resistant to water. It also offers better strength when it comes to weight ratios. The material provides a very high tensile strength.

PTFE (Teflon)

This is basically a plastic substance with no resistance. For this reason, it is utilized for fast speed and frequency applications. This material has a lot of advantages. For instance, it is very flexible, making it priceless in applications having tight tolerances. Additionally, it is very lightweight, making it usable across different industries. Moreover, it is flame resistant, has great physical strength, temperature stability, and quite versatile in application.

Metal

This is a conventional material of copper and aluminum, among others utilized in PCBs. They permit the usage of Surface Mount Technology for the incorporation of components. They also have mechanical durability and, therefore, can be used for long.

The Future of PCB Material

The shrinking of the electronic devices will lead to the production of smaller and densely packed PCBs. These products will have significant electric potential. The development beyond the boards we just discussed here comprises of 3-dimensional molded plastic boards as well as the increased utilization of the integrated circuit chips. For this reason, the manufacture of PCBs is likely to be more dynamic in the years to come.

The Bottom Line

PCB materials have a lot of characteristics. It is essential to consider all these characteristics are essential, and you have to consider them when selecting the materials for use in this regard. Some characteristics, such as decomposition temperature and glass transition temperature, are significantly affected by temperature variations. For this reason, you are supposed to consider the temperature of your working environment when selecting PCB materials.

2020.02.09 22:55 LarBrd33 The Oscars use a ranked ballot to select Best Picture. Let's see who Reddit would select using that voting system.

Many people don't understand how they vote for the "Best Picture" in the Oscars. Explanation if you don't already know... Oscar voting uses a preferential ballot system. In short, voters rank their favorites from 1-9. If a movie doesn't have over 50% of the vote, they throw out the movie with the lowest #1 votes, and the #2 choice on those ballots becomes 1st place votes. They keep doing this until a movie has over 50%. That's how you end up with "Green Book" winning. It can end up being the least-divisive film instead of the one that got the most true 1st place votes. Here’s an article explaining it.
I'm curious who Reddit would select as the Best Picture Winner tonight. I figure we can do it like the actual Oscars and force voters to rank them 1-9 (winner needs over 50% of the vote).
Here's a quick ranked poll I set up: https://rankit.vote/vote/1a8o3SQVzZAAZugFmPbc
I’ll keep this poll open until mid-way through the show.
Edit: I figure 10,000 votes is a good place to end this.
Some quick notes before the results thoughts. Keep in mind the demographics of Reddit is going to be quite a bit different than the actual Academy voters. Someone did a survey a few years ago and found that roughly 15% of Redditors were under 17 years old, 57% age 18-25, and another 23% between the age of 26-35. 82% were white. 65% were male. So if true it's mostly young white dudes here and that could impact a movie like "Joker" being as high as it is.
Compare that to the actual Oscar voting body (8000 people), they claim it's around 31% female. 34% people of color. Haven't found any recent data, but supposedly the median age was around 62 years old...
So their choices might be pretty different.
That said, with 10,000 votes Parasite was the easy winner here:
Round 1:
  • 45.7% Parasite
  • 15.1% 1917
  • 10.4% Joker
  • 10.4% Once upon a Time... In Hollywood
  • 6.9% Jojo Rabbit
  • 4.6% Marriage Story
  • 2.8% The Irishman
  • 2.3% Little Women
  • 1.7% Ford v Ferrari
Round Summary: Parasite is leading but no choice has over 50% of the votes. So, the choice with the fewest votes, Ford v Ferrari, will be eliminated. Voters who chose Ford v Ferrari will have their votes redistributed to the remaining choices based on their next preferences.
Round 2:
  • 46.2% Parasite
  • 15.4% 1917
  • 10.8% Joker
  • 10.6% Once upon a Time... In Hollywood
  • 7% Jojo Rabbit
  • 4.7% Marriage Story
  • 2.9% The Irishman
  • 2.3% Little Women
Round Summary: Parasite is leading but no choice has over 50% of the votes. So, the choice with the fewest votes, Little Women, will be eliminated. Voters who chose Little Women will have their votes redistributed to the remaining choices based on their next preferences.
Round 3:
  • 47% Parasite
  • 15.7% 1917
  • 10.9% Joker
  • 10.9% Once upon a Time... In Hollywood
  • 7.4% Jojo Rabbit
  • 5.1% Marriage Story
  • 3% The Irishman
Round Summary: Parasite is leading but no choice has over 50% of the votes. So, the choice with the fewest votes, The Irishman, will be eliminated. Voters who chose The Irishman will have their votes redistributed to the remaining choices based on their next preferences.
Round 4:
  • 47.9% Parasite
  • 16.2% 1917
  • 11.8% Once upon a Time... In Hollywood
  • 11.3% Joker
  • 7.6% Jojo Rabbit
  • 5.3% Marriage Story
Round Summary: Parasite is leading but no choice has over 50% of the votes. So, the choice with the fewest votes, Marriage Story, will be eliminated. Voters who chose Marriage Story will have their votes redistributed to the remaining choices based on their next preferences.
Round 5:
  • 50.2% Parasite
  • 17.1% 1917
  • 12.7% Once upon a Time... In Hollywood
  • 11.9% Joker
  • 8.1% Jojo Rabbit
Round Summary: After 10237 votes, Parasite wins.
FWIW, I did two other polls like this. One in a private group I'm in dedicated to watching tv/film. The other in a private group I'm in made up of local film/video production professionals. In both those polls, Parasite and 1917 were the frontrunners, but 1917 ended up winning. Also in both of those groups, "Joker" was one of the first movies eliminated... so hard to say how reflective this will be of the actual voting body. Thanks!
