- A Printed Circuit Board is the backbone of all the modern day electronic devices. Let’s explore what a PCB is and how these tiny circuits are manufactured. This video explains how a PCB is made with help of Gerber file, chemical etching and UV process all starting from a copper plate using THT technology.

I have experience working for a pcb manufacturing company in South Korea.
We made the product at the request of Intel, Samsung, and SK Hynix.
Most of the processes are automated. However, it is necessary to always monitor whether the automated facility is operating properly and change the data according to the conditions of the product.
I had to constantly doubt and check the results of the machine.
For example, in the plating process, whether it is gold or copper, what is the thickness of the plating, whether the plated surface is smooth, or if nothing is plated other than the design... I had to check one by one using a magnifying glass.
Even when working in the painting and marking parts, I always had to check all the results one by one.
The reason why people have to check and control each and every one of them is because...
It's because PCB is 3D!
The plane of the pcb is not a complete plane. Plated and circuit-injected areas protrude, and holes are in.
Production drawings and films are paid on the assumption of 2D without considering 3D.
Especially during the ultraviolet exposure process, the film adheres to the pcb product.
Because of the difference between 2D and 3D,
Fine differences occur.
If the size ratio between the film with the drawing and the actual pcb is perfect 1:1, the film becomes almost unconditionally small due to the 3D of the pcb.
Therefore, a slightly larger film is provided than the actual product.
When production workers actually make it, some parts of the film are small or large.
In some cases, the drawing film may be modified several times.
These tasks should be checked one by one using a magnifying glass.
It takes a long time, my eyes are stiff, and I'm stressed out.
The higher the density of the circuit, the higher the production difficulty.
This is because there is a high probability of interfering with circuit imprinting, plating, painting, and marking.
Damn underrated comment
You have a wonderful job, mate, not everyone had your expertise.
At least some places have a manual step of aligning a transparency with black lines on it.
For green boards not a problem.
Some customers order black PCBs.
Some customers get cursed at when they can't hear.
_In todays technological advances it still boggles me in the fact that we’re still using copper instead of silver, The most electrically conductive element is silver, followed by copper and gold. Silver also has the highest thermal conductivity of any element and the highest light reflectance. ... As to why silver is the best conductor, the answer is that its electrons are freer to move than those of the other elements_
_I’m guessing that we have to request a custom design motherboard using pure silver over copper_
@@TacticalTrucker
And what do you do with it a couple weeks later when the silver is tarnished?
I've read hundred time about single multiple layer PCB each with different etching Technic but animation makes is look even more easy to understand
I remember working with my first multilayer boards doing component level troubleshooting, in the 1980s, what a pain. I worked in electronics and telecommunications for a time spanning 51 years. I first worked in a tv repair shop at the age of 16 in 1970.

I am waiting for your next video on SMD PCB.
Same here and Im still waiting.
A printed circuit board.
Thanks
Thx
Great explanation 🔥🔥🔥
Mind blown. My university was a waste
Take my tuition money 💰
Thanks for placing PCB order on us! This video is amazing, learned a lot! Feel free to let me know if you need more PCB in your next projects.

Thank you so much for the information how PCBs are designed from bare board to designed one.
PCB or Perfect Cherry Blossom is a seventh official game of Touhou Project franchise. It is a vertical scroll-shooter, also referred as Bullet Hell or Danmaku shooter, where danmaku means "barrage". Games of this genre are famous for a great amount of bullets and some other projectiles being shot into the player's character. This game is considered one of the easiest in the franchise and thus one of the best starting points to start playing Touhou. Touhou Project is also famous for it's great music. Game presents three playable characters with two shot type each. The unique features of the game in the series is the Cherry points, which can multiply your score or launch a Barrier that can protect you from enemy bullets or give you a lot of score for not losing it until it's time runs out. Also after the so-called Extra stage which is common for other Touhou games and is unlocked after beating the game on good ending with any character, there is additional stage, the Phantasm, that can be accessed after beating Extra.
The game introduces several characters which are still very popular up until today, such as Alice Margatroid, Youmu Konpaku, Yuyuko Saigyouji, Chen, Ran Yakumo and Yukari Yakumo.
The game tells the story of so-called "Spring Snow Incident". By some unknown means, the spring didn't come to Gensokyo, the fantasy land where all of the games take place, resulting in winter continuing all the way untill may. Follow the heroine on her way to investigate the incident, defeat powerful enemies and bring the Spring back to the Gensokyo!
You're the best

Sooo thankfull to all of you
Sending my love from egypt ❤️
PCB... Printed. Circuit. Board.... it all makes sense now 🤯
Really a masterpiece thumbs up
thankyou for giving us knowledge through the 3D view, it is very hard to do this animation and I am really thankful that you do all this for us
This is brilliant....hope to see televised production soon
It's a good thing that it's already in my recommendation since I've been curious about it, but always forget to look it up.
I been wanting to know how these are made ever since I was a kid. Thank You so much 😀
Touhou YouyoumuGhostly Dream[1]~ Perfect Cherry Blossom (東方妖々夢 ～ Perfect Cherry Blossom) is a vertical-scrolling shooter, and is the seventh official game in the Touhou Project.
Simple but perfectly explained The PCB manufacturing! Keep it up Team :)
This came from my recommended after watching a bunch of touhou videos, and I get the feeling TH-cam fully believes the answer is "Perfect Cherry Blossom"
How conveniently you have explained the introduction of PCB....Greatfull
Thx man,you don't know how it helps me to start my way to mechatronics
Clearly explained. An excellent video with beautiful animations
Superb. Thank you so much for all your video. It's all are very important and useful. And it's important for growing the knowledge. 💓
Very informative! Thanks for putting this out. I'll be keeping an eye out for the surface mount version
Clearly explained. Thanks for the effort.
very clear and concise explanation with the animation on point . thanks
Ur awesome. I've been watching your channel since the last 5 years.
Thank you for this excellent explanation, keep going strong with this, kind regards.
Sir you are making great vedios , i really like the way you teach ,you are the best teacher i had ever find on youtube
Amazing, never knew those things. If you can post a video how to fix moderm PCBs yourself it would be the most useful information in my life.
Y'all's video and animation quality has gotten so good! This may be my favorite you've done. Keep up the great work!
Hands down one of the best 👌 videos
very good video for people to know printed circuit board .
Great content as always, thank you
Thank you for the excellent video.
This is hate about youtube and Audience...Informative videos remain With less views while Nonsense and time wasting memes are trending...
This channel is Gold
they have over 4 million subs lol they're doing very well
@@HamedAdefuwa subs always not equal to views... only some video trend and get popular randomly
Thank you very much sir for this wonderful video
Thank you this was very informative since I had no idea what TTM Technologies did here in Ohio literally just left an interview for an entry level position and I’d be making circuit boards for Air Force defense missiles this was the exact process I just saw during my orientation
you are not funny, get some help
Im gonna wait for the SMT video. Very good job.
Just amazing explanation
Most PCBs are green because most PCBs are green. You can get red, white, or black.
But the tanks have to be emptied and refilled so you either have to wait until they a lot of orders for other colors or pay extra.
And the military was the first to pick a color.
very very helpful, I was looking asking this question for years. this video was wonderful
MY DOG DIED
I learned making crude ones with just a pen this copper sheet and that alkaline solution.
This is a weird way to describe Perfect Cherry Blossom but good video regardless 👍
Thank you , it is very easy to understand now. ❤
Been using autodesk eagle. Mostly because you dont really need the paid version to do simple PCB's. It's also easy to use as long as you get how it works.
I've never thought of it like that.
Really brilliant!
This seems fun!
Amazing video...it couldn't be explained better than that.
IT COULD
This is the fancy version.
The broke version involved a piece of paper, a flat iron for clothes, and some luck your circuits were good. Put the paper with your circuit board traces on it which you iron onto the copper board, use acid to etch it in, put a silkscreen and laminate it and boom. Nowadays it's a lot more automated and precise.
Thanks for your videos I learn a alot
"Perfect Cherry Blossom"
IN FACT simply awesome...very very understandable..similarly like all your videos bro..
Isse simple or nahi ho sakta
Thankyou sir
👍👍👍👍👍
can you explain more about Electronics, DFM DFA, multilayer boards, need to understand more about circuit design, component spacing etc.. interesting channel, you guys have excellent future.
Your voice is amazing on whole you tube ❤️.
I learned a lot From This Videos. Appreciate Your Hard Work On Such Simple Explanation And This Amazing Animations . 😃
One of the best science Videos on TH-cam, amazing Animation, super simpel and understandable and very good Voice, absolutly amazing work guys👍
Great explanation 👍 Please upload a video about Wafer electronics and IC chips
Thanks for sharing
It is explained in details
Thanks, Sir! Appreciate it
Very nicely explained. Impressive.
UITS TERRIBLE
Well done!
thank you!
Damn, I never was curious enough to learn this and I'm enjoying it
The explaination was clean and you had my attention from start to finish
Thanks for the video!
very nice 3d video with good explanation.
This video was very well explained and I learned a lot. Thanks
Best explanation!!
Amazing video. Thank you.
Excellent video, thank you very much
Amazing!
I love the information
Well I love all of the three most basic engineering disciplines viz Chemical, Electrical and Mechanical engineering but I feel overwhelmed by Electrical engineering more than the other two.... just about 150 years of history but pioneering in almost every part and form of our artificial physical world.
You love making this with things are benefit for your life..
Well explained, cool information,thanks :)
Printed Circuit Board ( PCB) Chip board All Electronic components have this board wow Awesome Animation explaination how PCB manufacturing & Soldering Components using liquid Tin ( THT ) (SHT) Hole technology 👍👍👍👍👍👍
Gerber files do not contain 3D model information. Gerber files contain the information on each 2D layer in a board. There’s a drill file for the entire board and a layer file for each layer in the circuit board.
Gerber data is photo plotting data from the 80's for the textile industry(AFAIK).
With a couple updates over the decades.
It is amazingly primitive.
And the drill data is usually included in a layer now.
@@stephenolan5539 drill data is not included in the layer. Drill data has an nc drill file. There are voids in the copper where a drill will pass through but this is not drill data. The copper would be removed in an etch but there would be no hole in the core.
@@RedHaloManiac95
Then how was I looking at drill data in gerbera this morning?
I was looking at drill holes vs masking.
Some holes that were masked on the customer's gerbers were not masked on the board shop gerbers.
And the board shop was not given a separate file for the drill locations.
Clearly explained
Thanks for such great quality contents 👏👏👏
ITS SHOCKING
Informative topic
Thank you
amazing technology 👍
Great Information sir.... Excellent ...More valuble..... 👌👌👌👌👌
Thanks a lot! nice one
Wonderful sir🙏🔥🔥
Thank you so much for the information😁 keep it up sir 😁
They are like boards where you can have separate inputs and outputs like connect a battery then add electronics
That's a beautifully made video
Loved the video and I learned a lot but it was fun
Loved it!.
FANTASTIC!!!
Very informative!
Thank you so much
Amazing
cant wait for the smt video!
