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.
@@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.
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.
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
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 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.
hi sir I am a student who is inspired by your informative videos and on the path to become an electronics and communication engineer sir i am goig to start my journey in field of electronics next month i.e. start of my engineering journey. thanks alot for inspiring me and others.
Thank you for making these videos. Im from a poor country where information like these are very scarce. So having high quality education for free is helping me out greatly. Thank you so much
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!!
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.
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.
This video very well describes what PCBs are. I have only a couple of small little quibbles with the video: the video doesn‘t show the large scale end of networking PCBs and it doesn‘t explain how with the use of flex-rigid PCBs, the number of connectors in a device are greatly reduced and signal integrity is greatly enhanced. But again these are truly quibbles! This is an excellent overview of the humble PCB using the modern cellular phone as a “show-and-tell” vehicle. I have worked in the PCB industry for nearly 50 years now and can attest to the great and accurate job you have done here in making this video.
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!
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.
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!
Dude.. I am an engineer recently taking care of reworking PCB.. I was kinda lost on where to start my career.. But when I watch your video, now I have clear vision to carry out my task.. Lots of thanks from Malaysia 🇲🇾
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 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.
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 👍
Year 1992 I was a 16 year old boy I made a wireless transmitter and receiver myself, for that I got some awards, now i'm a professional machine tool designer. I really wonder the development's in this electronic industry especially in mobile phones technology. Your multi layer PCB animation was superb thank you.
This is an amazing video. My professor cannot even explain how PCB work in one quarter, but I find this video is very helpful. Recommend those EE students watch this video before then move onto designing the PCB. Thank you for the video!
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.
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!
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!
So glad to have stumbled upon this video. As a student currently studying computer engineering, I have yet to find a professor who, although brilliant, can convey a topic with such clarity. I'm sure this was a difficult and time-consuming video to make, but know that we appreciate each hour spend and it truly is inspiring to see the genius in this video. Will most definitely share with classes!
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.
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!
Thanks a ton! Yeah, the semiconductor industry was a ton of fun, but I believe that engineering education has a lot of potential and is in need of reinvigoration.
@@BranchEducation I have read the mission/vision page on your website and one line says: "The focus overall is to teach systems in their full complexity", your work itself is a reflection of your mission, Sir. I hope your videos get watched by everyone who needs to watch it.
This is one of the videos where you get glued to the screen with astonishment. I was like Wowwwwww ( literally with lots of w). This is beyond amazing. More power to you.
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.
I'm a Senior Electrical Engineer with expertise in ultra miniature electronics designs. Very nice presentation! Another important factor is high-speed signals require controlled impedance, which is determined by the material properties and geometries of the features on the board. Very complex physics principles at play (electromagnetism)!
That's a very good point that I should have added, if at least in a sentence or two. Thanks for the input, and for enjoying the video. What's an example of ultra miniatures electronics?
@@BranchEducation it was still an exceptional video. I've designed very small IR cameras (20mm x 20mm x 18mm), GaNFET laser pulsers, and many other electronics to interface to custom image sensors. Cell phones probably take the cake for some of the most complex, miniature electronics. Still, the pixel pitch of IR detectors (we have the world's smallest at 5um) is typically larger than visible detectors due to the physical materials (indium gallium arsenide, mercury cadmium telluride, ect.). The problem with Mid-Wave IR (MWIR), is that the materials have to be cooled down to 100 Kelvin or below to function properly due to thermally excited current carriers.
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.
I also have to say, I actually learned answers that I've been looking for... thankyou for your accuracy...the fact that knowledge can be precise and to the point is helpful and not boring!
Your videos are very informative animated ones! I downloaded 14 of them and this was 9th one. Technology is important and interesting, it is necessary there must be an explainer like you as well.
Hats of for your HardWork i am not a student Don't have much Qualifications But always wanted to Learn Technology what it takes behind these magical Devices A Hardworker Person like You DESERVE much more for making People understand The Complicated Engineering
Big thumbs up for the mid-video message, inspiring people to pursue a career in STEM. Great appreciation shown to those that make our smartphones a thing.
I am Msc Computer Engineer, the guy give the live of the devices. I am able to design pcb but thanks to hardware designers and their sub teams, they are developing way more complex pcbs than we can do.
Very instructive and informative video. The graphics are sophisticated and leave no room for doubt in the minds of the viewer. Never knew that every day I have been using such a complex device. I saw a video on touch screen. Another on SoC. Now, this one on PCB in a cell phone. I hope that one of you geniuses will make a single video explaining cell phones in its entirety. Awaiting with bated breath! I had a client who provided single layer PCBs for entertainment electronics. That was almost two decades. They went out of business because they could not master the technology of making of multi-layered PCBs! Technology ruthlessly discards anyone who cannot keep pace.
thanks for the great video... these things never taught in school nor never studied so much detail in my engineering. clear and excellent detailed informative video about PCB. Teddy you are awesome
Hello, this is the most amazing pcb presentation I have ever seen. I know just a little about pcb but I want to learn more about them and understand how they work so I can diagnose and fix them, being a computer or a cell phone. I would really really appreciate you or anyone here that can point me in the right direction or recommend any book that I can begin or completely learn from. Much regards, Thanks 🙏🏾
This things are so simple yet so complex that it amazes my mind how a bunch of genius people make invent this things. I'm a computer engineer student because i was always amazed how we can make so much amazing things

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.

I saw a video on touch screen. Another on SoC. Now, this one on PCB in a cell phone. I hope that one of you geniuses will make a single video explaining cell phones in its entirety. Awaiting with bated breath!
I had a client who provided single layer PCBs for entertainment electronics. That was almost two decades. They went out of business because they could not master the technology of making of multi-layered PCBs! Technology ruthlessly discards anyone who cannot keep pace.
thanks for the great video... these things never taught in school nor never studied so much detail in my engineering. clear and excellent detailed informative video about PCB. Teddy you are awesome
Whoever animated this seriously well done
Teddy You cleared my all doubts about motherboard its components and its working from ground level...thank you.. Love from india🇮🇳
Your hard work is appreciated 👏🏻👏🏻👏🏻
Thank you for taking the time to make this video. You explained everything well, and I learned a lot!
Hello, this is the most amazing pcb presentation I have ever seen.
I know just a little about pcb but I want to learn more about them and understand how they work so I can diagnose and fix them, being a computer or a cell phone. I would really really appreciate you or anyone here that can point me in the right direction or recommend any book that I can begin or completely learn from.
Much regards,
Thanks 🙏🏾
10 minutes of pure knowledge , honestly learn alot
You can explain it well enough, so you know the stuff. I enjoyed every bit of it....thanks
Your Videos are awesome! You let someone see what nobody has ever thought of!
That is the best video I watched on the subject!
That was mind-blowing. You really work so hard to creat this animation and you also took care of every single small detail.
Learned a new full form of SMD, thank you.🐒
Edit: In all seriousness, hands down "The Best" video about PCB on youtube.
your channel and videos deserve billions of likes and subscribers !! thank you so much
Wow. this is a no BS explanation on how a pcb works. thanks for this.
Brilliant animation, top class...💯👏👏 Simple Education that's beyond Varsity levels...
This things are so simple yet so complex that it amazes my mind how a bunch of genius people make invent this things. I'm a computer engineer student because i was always amazed how we can make so much amazing things
