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?
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
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 :)
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 KZhead 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'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 wish I could give thousands of like to these video
That would be convenient if people could give multiple likes.
:D hahaha
Can you please do a video on the "making of this video". Thanks.
The comment I was looking for
Me too
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.
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.
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!
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!!
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!
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!
Mind blowing. This video highlights just how impressive the engineering behind our devices is.
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.
The amp hour podcast (eevblog) pointed me to here. I'm glad it did. The amount of work and detail is amazing
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
Dude you are an inspiration to the new generation of Electrical Engineers, keep on with your good job!
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 absolutely love taking electronics apart and learning how circuit boards work! Thanks for this video, it explains a lot!
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!
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.
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 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.
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?
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.
You can explain it well enough, so you know the stuff. I enjoyed every bit of it....thanks
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!
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.
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 channel is a gold. Beautiful 3D animations, tons of knowledge, everything explained very clear. I can't wait for future videos. Thanks for your hard work!
Hands down one of the best educational videos I have seen. This is pretty much Discovery 2.0. Thank you kindly
The intellectual stimulation I needed.
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 👍
This is just so darn EPIC man! Thanks a ton for existing hahah, keep up the good work!😄💎💎💎
I was looking for a cool video to help update my knowledge of circuit boards ... and have come away blown away by the quality and level of detail that's in this video. It's incredible to see how the technology for PCBs has rapidly been updated and even better to see the cool things we can now do just to explain that tech. Thanks for putting this out there!
As usual, this is an absolutely amazing video!
Thanks!! It's much appreciated!
I really love it Tnx so much for explaining. God bless us.
Thanks! Glad you enjoyed the video.
That was mind-blowing. You really work so hard to creat this animation and you also took care of every single small detail.
4 years after, I still love what you do . Thank you!
Very detailed animations and best explanation. Thank you for this interesting video
Thanks a ton!
It's so informative and well-explained about PCB. Good job !👍
Supported by a famous PCB manufacturer 😉
Thank you for the amazing animation. This help me with visualizing PCBs internal constructions.
One of the best channels explaining working of electronic gadgets and technology in detail. Great work. Thank you.
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 learned from you more than even I could be learning in school for 10 years. Thanks, a lot man; your explanation is Immaculate.
This is just awesome, your footage and animations. Great job!
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!
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.
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.
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.
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.
The animation is so so so good. And the explanation is so so so clear. Truly great work.
omg! the graphics in this video, the way you explain everything!! congratulations, it's a great work! subscribed
"There is one football field..." And that, kids, is how i knew he was american
Hello
Top notch animations with simple explanations that don't misrepresent any technical detail. Awesome content!
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.
Frim Lucknow
Your passion for explaining things is what blew my mind
This is brilliant! I hope much more videos like these exist on this channel. Just started exploring it. Thank you so much
Absolutely amazing video🔥🔥🔥 Highly appreciate your work dude ❤️
Wow..the best animated educational vedio I have seen so far on youtube
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!
That is the best video I watched on the subject!
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
What a wholesome way to finish the video. Thank you, it was amazing :)
The animation work and the explanation is top notch in this channel. I can't imagine I am watching this free. Wow!
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.
That's a great presentation. I've learnt a lot today. I'll come back for more. Thanks
Such a simple yet intricate process! Very informative video.
Wow. This man is very knowledgeable and speaks with much clarity. I'm thankful for this video. I hope I can learn more about this soon.
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!
Thank you tons, especially for sharing it with your class.
all i can say is thank you for your hard work and attention to details that make learning the way it should its got all the right ingredients... every video is amazing iam just hoping you get the full the picture of how important and awesome your channel is please keep it up
i recognized the display of the LG V10 right away with it's small "second" screen at the top right, so it was awesome to see the V10's model with it's side rails
I just was curious about PCBs and this elaborated it perfectly. what an educational video. great animations...
Wow, such complex matters explained so well! This video is beautiful! 😭
May God bless your work, that was awesomely explained. Thank you
Great...!!! It was really helpful....just awesome description of a pcb through animation .... loved the video
The best education channel on youtube !!!! You deserve waay more subscribers !
i appreciate this animated video Branch Education. Keep up the great work! THANKS!
Will do!! Thanks for watching.
What took you (youtube)so long to recommend this channel ....😍😍 Quality content..future generation kids are so blessed to see such quality educational videos...love your work...thank you teddy ❤️
this is AWESOME. You explain it so clearly.
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.
10 minutes of pure knowledge , honestly learn alot
Wow that was superb. That made a lot of things I have been trying to understand, fall into place. Great work thank you and I can appreciate the effort you put into that.
Thank you for the hardwork you do. Much appreciated 👍🏽
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.
Love the graphical illustrations! Thank you
your video quality is insane liked for sure!
Brilliant animation, top class...💯👏👏 Simple Education that's beyond Varsity levels...
How amazing your videos are! detailed and complete! Keep going and make more amazing videos like this!
You have some amazing stuff and very detailed animation. Too much hard work is reflecting on your videos. keep it up.
This man is a living legend. Again, thanks for the great video.
