You taught me in 11 mins what my Design teacher did not for entire year.. There is a lot of hard work behind your videos...Thank you very much..God bless you.

Step 0: Know wtf you're doing to begin with.

This is officially my favorite video on UKposts. I've always wanted to make my own PCB happen but never had it felt more approachable or attainable than after watching this.

Couple other tips that I've picked up in my time in industry so far is include testpoint vias (and local ground points) on almost all major nets/connections! This will help debugging PCBs by making it easier to pop in scope probes. Another thing to keep in mind is power domains and signal domains. You usually want to keep these separate as much as possible to prevent interference (Along with some nice ground floods to help isolate fringing fields). In terms of routing, it always helps to route your major signals first (i.e. RF paths > High Bandwidth Serial Paths > Low Speed Serial Paths > HF Power Paths > LF Power Paths > GPIO Lines > Power) as this will help signal integrity and generally make it easier to route.

0:24 I love how you actually demonstrated soldering SMD parts to a perf board :D

So THAT'S how it's done! I'd been muddling through this process making all kinds of mistakes and wondering how so many people with a lot less time in electronics than I were able to do it so easily. Nice to finally be able to connect the dots, literally. Thank you for this!

"trust me, I'm an engineer" 0:25

I have not any experience with ICs; the most I've messed with circuits is soldering some LEDs, BUT you always get to keep me through the video and I actually think I understand most of it. Well done and thank you truly! You're an example of a content creator!

I am loving JLCPCB! From part picking, to schematic, to layout, to ordering the PCB and BOM.. all super seamless and easy! I'm not even getting paid for this, but I am really digging it. Glad I saw this.

I was just looking for a video like this, not going into too much detail but showing the overall process, but just enough so i got a better understanding and the main pointers needed. Thank you for this, it's a gem among the many electronics videos on YT, you information and production level is always spot on!

An easy rule of thumb you can use for trace widths is 10 mils (0.01") per amp. Then you only need to bust out a calculator for the really high current traces.

I'm an electrical engineer and i love your videos. never stop

Seriously, this is one of the best videos on PCB design. I am proud to be your patreon. Keep it up!

I love watching your videos. Honestly, your voice makes whatever your talking about seem interesting. It makes me want to learn. So thanks.

As commercial as this video is (in a tasteful and subtle way), I personally still love it. You share the best things on this channel and it’s always a joy to watch. :)

Time for GreaScott to change the intro to a PCB then !

90 degrees bends... It's an issue of EMI and wave propagation problem, as well as manufacturing hazard. Electrical wave passing through the copper prefers a straight line, as almost everything in physics. 90 deg bend causes the wave not to propagate properly, some of the signal might be lost or reflected. It may also interfere with other signals in the circuit. This is essential for high speed signaling where you have to keep the trace of the said width to set it to proper impedance so it can match the rest of the circuit. For the manufacturing, the more acute the bend the more risk of resulting track being "over-etched", which means being thinner than expected. With thin tracks it could lead to bad signal integrity best case and an open circuit worst case. The other thing is that a good practice is to make the supply voltage traces as thick as possible for low inductance and low voltage drop across the trace, especially with currents closing to 1 amp and above.

This tutorial is just perfect. Well explained, not boring with details and straight to the point. Keep it up!!

Fantastic video! I followed your instructions and PCBed my latest creation. Your instructions worked perfectly, and my creation works beautifully. Thank you!

As an electrical engineering student I love you channel. I am just leaning about designing circuits and... Your channel gives me lots of informations and new ideas.

My eyes hurt when you soldered that SMB IC to the perfboard :'D

I have actually made my very own PCB with this tutorial, and it has worked the first time off. Not too complicated but it is great to see your design worked first shot. I have since made revisions 2 and 3 to improve on my design. And bonus, it looks professional.

This video helped me out SOOOOOOO much! I've been designing electronics for years, but I'm very new to this software! Thanks to this video, I've figured out how to design PCBs very quickly! Love this channel!!!

Un millón de gracias por todos tus videos! Yo soy Ingeniero en Energías, pero siempre fuí un apasionado de la electrónica y he hecho algunos PCB's que la verdad, da mucho gusto verlos funcionando.

Excellent tutorial.

greatscott is really great for his public service to spread his own wisdom to others. best wishes to continue you work. thank you for your video.

Will be studying videos of working on pcb designing for motherboards. I just actually today got a job working for a company I am excited. This is my first time ever doing this and all the help I can get is highly appreciated. Got this weekend to do this test thanks for the video and creating this.

Great work brother

GreatScott new video - heatbeat over 9000

i watch hundreds of tutorials but non of them was as good as yours! keep like that! thanks

Wow, what an inspiring video!! !I've been meaning to make my own PCBs for years, now I'm going to start...one something really simple! Awesome channel!!!!

Dhanyavaad Sirji

You really passed from idea to PCB, nice video. I see the bottom layer doesn't have copper fill. Did you had a reason for that? Keep up!

I have recently got into electronics as a hobby. I had a class on electronics in high school 31 years ago. It's amazing how much easier it is to design and produce your own PCBs now. Computers and the internet have changed how we do almost everything in our lives.

Thank you,you should get a Nobel prize. I’ll be doing their tutorial soon, and starting simple with some boards for ws2812 arrays. Keep up the outstanding work you’re a legend my son.

Where are your clearance settings? Also did you do DRC checks? What can't you set power net to a specific width beforehand? I think you should talk about these "safety issues" before drawing your PCB.

Pretty neat tutorial!. Once you shoot for more advanced projects, I would always suggest to go for 4 layers, so you can have two signal layers (front/bottom), a dedicated ground layer and a power layer inbetween (if single supply - for dual supply, use the back for the secondary voltage). This also gives you more freedom while routing. One thing I have missed was an extra note about bypass caps for active components. I have already seen people designing PCBs either not thinking about bypass caps or if they did, they "grouped" them together in a single block, far away from the active component. Rule of thumb: Put 100n as close as possible to the power pin of an active component.

A really good video on the whole design process including ground plane. Loved it. Thanks!

In deinem Videos habe ich mehr gelernt manchmal als wie in den Vorlesungen. Danke für die Videos!

3:58 - that darn greedy LED.

This is a great video on the general process of PCB design. I really like that you have included the step of creating a plan in the form of a block diagram. Though I'm disappointed that you've left out the importance of design rule checking. Every beginner will benefit from the use of DRC! It can point out some blatant mistakes likes shorts, unrouted nets, holes that are too close to each other, etc... This will save you time and money. The design itself could be improved in several ways. For example: C3 is placed in a way that beats its purpose. The die pad of U2 should connect to GND and have a bunch of vias connecting to the bottom plane to help with heat dissipation. The RF module should be placed so that the antenna is somewhere near the edge of the PCB pointing away with no copper near it. If you place it right above other components and metal objects it will shorten the range and degrade the signal. If you haven't, go watch some Robert Feranec's videos. He has a ton of tips on good PCB design practices and techniques. This can save you some money and headaches in the future if you know what to pay attention to.

Another excellent tutorial!!!!! Probably the best electronics tutorials, by far!!!! Thank you for sharing your knowledge!!!

I must say Great Scott this is the BEST PCB video I have ever watch on UKposts. Am your biggest fans I Love You

idk why this is so interesting when I dont know anything about everything you talked about lel

"You cannot solder an SMD component to a perf board" - "Hold my beer" 0:24

This is a very useful video. One that I anticipated to come from you. Thanks again. I'll try LCSC for parts, been a big issue all this while to source parts.

i've studied electronics, i practiced at a company which repaired TVs (among other things) - the beginning of the plasma screen era, the first SMDs appeared back then - and I was never taught that I could solder SMDs with hot screwdriver (only the hot air gun, - they said - method was possible! which...i never advanced enough to be tought that..) impressive & informative video!! thank you 👏

I just laughed my butt off at the part where you put the SMD onto a perfboard and made a globular mess of the pins :P

Been here since 200k🙂👌

Excellent tutorial. Most complete and systematic video on idea to pcb. Thanks

I'm a fan of GreatScott coz I learned a lot from his video, keep up the good work dude, share knowledge for a better world

Your soldering needs work, but I like your attitude and results. Thank you :) But.. what does your thingy do? (I missed that)

Great Scott Fans like here!

I don't really know much about electronics but I'm still learning. Great video & I'll have to watch this over a few times

Excellent explanation. I wish all tutorial videos were this clear.

I decided to give JLCPCB a shot. They charged me 16$ on my otherwise 2$ order for color.. I needed black for light reflection properties..

You don't need to go full SMD when you only want to use a few SMD ICs. There are little adapter pcbs on ebay for very cheap to fit an SMD IC into a through hole world.

Best hardware video for an aspiring electrical designer

This was perfect. It told me everything i needed to know and also clarified trace width for me.

I want to see all the papers on which you drew all those schematics.

I want to do this for a robot module that I designed and then sell it on ebay, but is it legal to do that? At what point do you need CE or UL certification?

Hello Scott! Great video and love the way you articulate. I have been viewing your videos on you tube and find you to be a real professional. Good information on developing the design from conception to finish product with the aid of free on line software. Most of all having the pc board perfected for the low price of $2. I had been considering purchasing a small three axis CNC mill and drill designed for the purpose of plotting, milling and drilling pc boards. The process you present here is a great cost savings. Happy to have found your channel and have subscribed.

I watched this video about two months ago. Since then I've tried out EasyEDA und JLCPCB. EasyEDA turned out to be a bit cumbersome to work with because slow page loads often interrupt the process and it is also too constrained for what I wanted to do. I've since then switched to KiCad. Great program. Also works nicely on my 12'' MacBook with the touchpad. The PCBs that I ordered from JLCPCB were of excellent quality. Every board worked perfectly.

Noob question: Isn't t the voltage divider for measuring the battery voltage draining the battery?

Yeah, the PCBs cost $2, but shipping to the USA costs $18 over DHL, which is conveniently hidden until well into the order process...

Thank you so much for this video! I have been struggling to get a PCB gerber file made with other programs, but EasyEDA looks like it's exactly what I need.

This is what I am looking for GREAT..... SCOTT....😘😘😘👏👏👏

Why noone of youtubers DOES NOT tell us about 10$ shpping costs, just the 2$ CHEAP PCB BOARDS. I know 12$ for 10 pcbs is not expensive, but everyone is allways talking about 2$.. deam

0:25 seems legit.

after a year away from EasyEDA s/w one is faced w/ many changes. frustrations being on the learning curve again. your vid' was just the cure to inspire me with can-do-ability . and has be back on track . hooyay for GS

Long time was waiting for this tutorial, Excellent

Not enough attention was paid to the GND... some of the GND connections would not handle 1amp current you could stitch GND near IC'S using via's

0:24 LOLOLOLOLOLOLOLOLOLOLOL

Fantastic vid! Love this channel. Excited about getting into this field

Thankyou for this. There needs to be more videos like this on youtube.

*hard laughting* 8:55

Actually, 90 degree corner is not a problem. The problem with 90 degree was that some older PCB EDA tools didn't support it, and it could crash it. For all other things, 90 degree corner is fine, as long as you don't run through it signal that has frequency of 9-10 GHz or more.

This video really helped me! Thanks so much! I used the auto router and it actually worked perfectly! Except for one tiny screw up that came upon me even before I used the auto router. But I just removed the trace and downloaded my gerber files. You just have to click a couple extra boxes that warn you there is a missing trace.

This was a great watch, concise and to the point, but descriptive enough to understand everything he’s doing… all while showing you good places to get the parts and website to design and order the boards. I have no experience with this and plan on doing a lot of trial and error designing a board to function exactly how I intend it to but I’ve been learning a lot online and on UKposts and I’m gaining confidence because of videos like this that I’ll be able to design something that will power and send something into a certain position from pressing different individual buttons and then wire the on and off to their own respective buttons. Any advice for things like this is appreciated, we want to wire up a wire stripper to run off elevator buttons so the button panel looks like the interior of the elevator using the 2,4,6,8 and so on floor buttons to strip that gauge wire and have the call buttons separate for on and off and have the top digital screen read on or off instead of the floor number it’s on. We didn’t get a digital screen from an elevator though we have to order one. We just got the even buttons from 2 up to 20 the door open close buttons and the up and down call buttons. We are trying to think of basic things we could build to design a board for to perform cool tasks in the little shop we are working on building. Again, any ideas are much appreciated lol.

It smells like advertisement

You have given me an answer for a question that I had for a long time, thank you very much.

This was really inspiring tutorial. I think I have to watch this video again when I design my next project :)

Just made my first PCB :) Thanks GreatScott you are awesome!!!

Thanks Scott, for yet another great video.

I don't know about anyone else but 'Let's get started!' for me means have a few deep breaths, stretch a little, chill, tune in and carry on watching and I'm not even majorly into electronics, I just like the art & craftiness of it all!

Really great tutorial, well presented and truly informative. GBU GreatScott!

You're approaching a million subscribers Haleluja Great job☺☺☺

Lol Scott your upload schedule is almost perfect. You upload ebike videos as I am building my own and now this PCB as I am designing one!

Very informative video! This has genuinely helped me as I was planning to get into using PCBs

Best intro video for PCB design

Great video! Very informative. Keep up the content I really enjoy watching.

Congratulations on 800,000 subscribers!

Yours vídeos are Amazing!!! Congratulations!!!

You are very thorough with your schematics!

Your paperwork (namely schematics) - is unbelievably professional and "neat"

You are GREAT, Scott.

they never taught me any prototyping in my mechatronics course, thank you for doing the work my school failed to do

I know nothing about pcbs, this was eye opening.

Excelent step by step how to start a production of a new product after development. I´m starting as a electronics product developper and it help me a lot thanks :)
