- What is inside of PCBs? Smartphones have dozens of components, and they are all connected thru a vast labyrinth of wires inside the PCB! So how exactly do PCBs work?
PCBs may be incredibly complex, however, they are rather easy to design and order. For a quick turnaround and inexpensive option for buying any variety of PCB, consider PCBWay: www.pcbway.com/

Which video topic do you want me to explore next*? I would like to know what you would like to learn more about and what I should prioritize. Potential Smartphone/Tech topics are: SSDs, LCDs, Wifi, Microchips / SoCs, RAM, GPS, wireless charging? Or I can jump into other topics like Quantum Computers or Satellites? Or would you like more conceptual engineering/physics topics such as 'What is temperature?' Note that next* means I'll work on it after the video I am already working on.
Ssd / memory management
microchip or SoCs
Rectifier
Oleds and other display technologies
The name of a transistor depends on which factor?
I am a PCB designer.. and every PCB designer should watch this animation before he start/choose this as career... Such an inspiring animation.
How do you go about designing a PCB? I feel like it’s more of a puzzle where you just try to fit the components you’ll be using onto the board
@@reyariass
According to what’s presented in the video, I’d assume you’d need a mission (what are you tryin to do?), a plan (what do I need?), and a design (how can I fit all this?). Then design the PCB. The components are subordinate to the design. You select the components to match the PCB, rather than designing the PCB to fit the components.
@@totallyfrozen There are tools that do autorouting of traces for you. They help find the optimal locations to fit everything.
Oh ok then i can ask you this because google has no answers and this guy dont find or read my now deleted comment: what type of steel and so on do you use to make this thing?
@@reyariass First we design a schematic with all component (eg- IC's, resistors, capacitors etc) which actually is an electrical circuit with its connections. then each component also have its landing pattern (footprint) associated with it. Then we start actual board design. PCB designing tools help us showing connections between pins of components from the schematic. then we place each component on some fixed board size such that there will be minimum overlap of signals. we route the tracks and send this design for manufacturing. hope you got at least bit picture.
Dude your videos are epically brilliant.
Thanks!! I'm glad you enjoyed the video!
Love your vids, can you review huawei nova 8 se? it seems great
Maybe photolithography in IC production has a similar way of doing it
You rightly said that....
See they don't break things :)
Teddy you took this video to the next level. I learned a ton! Keep it up
Thanks!! I'm glad you enjoyed the video!!
@@BranchEducation yes bro... Awesome content .... I am waiting for videos. Start about devices used in jet fighter and laptops
I am happy to see your comment here 🥰 I love your videos also 😍
Jared owen sir i want be your friend of Facebook or whatsapp.... My whatsapp number +8801768219001.
And Facebook link = m.facebook.com/profile.php?ref_component=mfreebasic_home_header&ref_page=%2Fwap%2Fhome.php&refid=8&ref=dbl
I will wait for you my lovely sir
This is what I call an educational animation, amazing graphics and great presentation
Thanks! I'm glad you liked it.
True!
Damn that's impressive, well done!
I can appreciate the work that went into that.
Now I know why RUclips recommended this video. Been watching you for nearly a decade, Dave!
I think I've watched at least 1000 full videos.
Now I now why I got this great video suggested.
The little break in the middle I was expecting a paid advertisement, was pleasantly surprised. I really appreciate that plug and agree 100% :)
It’s fascinating enough to picture this being made on a large scale, like the size of a table. It’s absolutely mind boggling that they shrunk this massive electronic city down to something that fits into your pocket.
I wish I could give thousands of like to these video
That would be convenient if people could give multiple likes.
:D hahaha
I'm a simple man. When people tell me what the distance is in both meters and feet, I'm happy.
Thumbs up and subscribed
I am an engineering student of ECE and these videos give me a lot of inspirations. Thanks a lot to Branch Education.
Lots of love from India.
Can you please do a video on the "making of this video". Thanks.
The comment I was looking for
Me too
Mind blowing. This video highlights just how impressive the engineering behind our devices is.
This is possible one of the best animations I've seen in this kind of a video. Hats off matie 🍻🍻
Thanks you tons!!
Still wondering how it was done.
@@brodriguez11000 same. I wonder too
I love your series. I worked on a main frame as a teen, making sure core memories were not compromised. We didn’t have home computers yet so I learned FORTRAN and cobol from a book, writing code with pen and paper, then pretending I was a computer and executing my code by hand. Back then, if code didn’t run from top to bottom cleanly, it was considered bad code. That made object oriented coding difficult for me to learn later. Things are so complex now, I feel like I’m starting over and your videos have helped tremendously. Whoever is doing your animation is doing a fantastic job. My career took me through post production and game animation so I appreciate the work displayed here.
how advanced is this? This technology is so vastly complicated and the necessity of precision (wire's not touching each other yet so close) makes my jaws drop.
Did you really take apart a cell phone, and de-solder all of the surface components to make these 3D models and graphics? Truly incredible work! I admire the work you do to make accurate, compelling, and clarifying visualizations for your videos!!
This channel is highly underrated. The animations are done very well, the audio is clear and easy to understand and everything ties in. Keep up the good work!
I remember when I used to be able to repair stuff with a soldering (not a silent "L" in the UK) iron and a few hand tools. After watching this video I don't feel so bad about not being able to do that anymore. Another wonderful video from you, and thanks for your efforts.
Superb job on this video! (It's the only in-depth one I could find on PCB's so far). One reason I really like smartphones is the embodiment of so many separate and complicated technologies, yet all working in harmony to deliver a good experience to its users. Please continue on!
Wow this was really amazing and thoughtfully well put!!
It is very clear that the amount of work put for just one video was beyond what most people do!!
Loved it!
The intellectual stimulation I needed.
Dude you are an inspiration to the new generation of Electrical Engineers, keep on with your good job!
Wow, such clarity in your presentation, excellent quality graphics. Keep them coming. Quantum computing and AI could be fun topics to hear about.
Thank you!! I have some really good visuals for quantum computing that I'll use once I get to that episode.
Hey Teddy! I just wanted to say thanks for making this video. Currently, I'm a college student studying to become a computer engineer. I 100% agree that more people should get exposed to these STEM-related fields. Technology will always grow; for example, when I experienced it in grade school, we transitioned from homework/lessons on paper to Chromebooks. Even during COVID, many schools use online resources to continue their education, thus influencing new ideas for how teaching in schools should be done. Overall, we would not be at this point in our lives with easy access to the WEB and other vital tools/resources if it wasn't for the thousands of STEM-related inspired students in the past. I also encourage others who are considering an education in a STEM-related field to give it a go as you never know what creative genius inventions you could produce to push the human race forward.
I knew that you must have done a lots of hard labour to present this beautiful knowledge infront of us.......
Thanks a lot ☺️
Keep it up
Thanks!! I'm glad you enjoyed it.
this is AWESOME. You explain it so clearly.
You can explain it well enough, so you know the stuff. I enjoyed every bit of it....thanks
The amp hour podcast (eevblog) pointed me to here. I'm glad it did.
The amount of work and detail is amazing
Wow, amazing job. I already knew pretty much everything in the video, as I'm a computer engineer, but I stuck around because the animations and production quality were beautiful.
Thanks tons! What type of computer engineering are you in?
That is the best video I watched on the subject!
4 years after, I still love what you do . Thank you!
As usual, this is an absolutely amazing video!
Thanks!! It's much appreciated!
Amazing explaination. This is the new way of learning. Reading it the concept will took a lot of time and processing, but you explained it in a very simple and understandable manner. Great job Teddy! Keep going and inspire the next generation!
Love the graphical illustrations! Thank you
I absolutely love taking electronics apart and learning how circuit boards work! Thanks for this video, it explains a lot!
This channel was an immediate subscription because of how organized and detailed your videos are. Your animations and research, it's wonderful and I really admire that effort. I'm excited to learn more and will happily share this!
I appreciate it! Tomorrow I'll upload an even more detailed video! Hope ya like it.
You are one of the best creator on youtube. I love to watch your videos and learn from your videos. Please continue making this kind of awesome videos and educating us. You deserve a great amount of subscribers. I appreciate your efforts. Thank you.
Thank you tons! I'm glad you enjoyed the video. I'll definitely keep it up.
This is just awesome, your footage and animations. Great job!
This is just so darn EPIC man! Thanks a ton for existing hahah, keep up the good work!😄💎💎💎
It's so informative and well-explained about PCB. Good job !👍
Supported by a famous PCB manufacturer 😉
The animation combined with the 3D models and real photographs is exceptional, this deserves to be a huge channel.
I work in electronics production and even I didn't know some of this!
I gotta say though, making these things is way, WAY easier than fixing them. I've seen some uh, interesting PCB designs too :P
Thanks for appreciating the video! It is SO much easier to make them than fix them. I've fixed traces on a 4 layer board with grinding and scratching out inner traces, but I have no clue how I would go about fixing a 10 or more layer board.
@@BranchEducation Honestly at my place we don't even get involved with trace repair, its components only and even then there's so much that can go wrong with board population!
@@BranchEducation I guess you're already aware of that :D, but no one fixes broken wires anymore. Most pcb's are modular, so you can easily swap out a broken pcb for a fresh one. The most you get is replacing a broken BGA, which is already a pain :D
@@Mike_droptv I'm familiar with that. I have in fact reworked PCBs in the past because of design errors. Cutting traces, rerouting, and reworks, in general, are a pain, but sometimes ya gotta do it to get design verification before respinning the boards.
@@BranchEducation Oof, that sounds like a hoot and a half. Fixing broken pcb's is one thing, but correcting design errors on the internal layers is just... these anxietys are kicking in again :D
Awesome video btw, love your work 👍
I learned from you more than even I could be learning in school for 10 years.
Thanks, a lot man; your explanation is Immaculate.
What a wholesome way to finish the video. Thank you, it was amazing :)
I really love it
Tnx so much for explaining. God bless us.
Thanks! Glad you enjoyed the video.
Very detailed animations and best explanation. Thank you for this interesting video
Thanks a ton!
Hands down one of the best educational videos I have seen. This is pretty much Discovery 2.0. Thank you kindly
Wow..the best animated educational vedio I have seen so far on youtube
Jay shree Mahakal, sir G ❤
8:51 those components are still called through hole components and they are still used today by hobbyists especially as they can be easier to solder.
I still have a ton of these components in a slew of plastic bins.
I am stunned not only by the content and presentation but also by the animations to help the understanding of this material. I have seen remarkable progress in engineering and science in my 70 years of life and cannot begin to imagine what the next 70 years will produce. How exciting to be young enough to be involved.
This is a masterpiece. This is just as beautiful as vintage IC chips. You know the ones I’m talking about… gorgeous chips with purple/white ceramic, Luscious gold pins and details, and visible traces on the surface of the ceramic.
This video is just as incredible! They are both amazing feats of engineering, and artwork!
For those who wonder how those intricate labyrinth of wires end up there so precisely, They are not put there, but formed from a sheet of copper over the FR4 or phenol board by removing the copper from the areas where it is not required. It is done by applying a protect pattern mask over the copper sheet where wires are to be, and then dissolving the unprotected areas of copper in a chemical acid or salt solution. It is called etching.
Sounds similar to how the chips are made!
i did shared and subscribed ..
anyone else ?
I did too!
Wow, such complex matters explained so well! This video is beautiful! 😭
Love this channel. Thanks for all the useful information.
It feels so mind-bending to realize I'm watching this video as the PCB in my smartphone is active in processing it... Kind of the same feeling I get when I watch a video about the human brain and realize my own brain is processing the information about itself. Woah.
Hello
You are great teacher... Kudos
How amazing your videos are! detailed and complete! Keep going and make more amazing videos like this!
"There is one football field..."
And that, kids, is how i knew he was american
Just amazing 😍😍😍can i know your qualifications ...if you want to share
Before dedicating my work to these videos, I was a Systems engineer for Ion implanters in the semiconductor industry. I got to see a lot of the microchip fabrication process. At university I got a degree in both Electrical Engineering and Mechanical Engineering.
Thank you for the amazing animation. This help me with visualizing PCBs internal constructions.
This kind of content is favorite on RUclips to watch.
