- 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_

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.

@@getartsywithyogita8291 That's a great attitude.
I always say to young people, "If you love the job you get, someday, you will get the job you love."
@@SALESENGLISH2020 😇 true sir.
I am waiting for your next video on SMD PCB.
Same here and Im still waiting.
25 years ago, as an engineering student, we designed our own pcb’s and “manufactured” our own self-made radios, and other electronic equipment

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

This came from my recommended after watching a bunch of touhou videos, and I get the feeling CZcams fully believes the answer is "Perfect Cherry Blossom"
This is a weird way to describe Perfect Cherry Blossom but good video regardless 👍
Sooo thankfull to all of you
Sending my love from egypt ❤️
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.
Thank you so much for the information how PCBs are designed from bare board to designed one.
This is brilliant....hope to see televised production soon
I learned making crude ones with just a pen this copper sheet and that alkaline solution.
Simple but perfectly explained The PCB manufacturing! Keep it up Team :)
Great content as always, thank you
Thank you for this excellent explanation
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.
Clearly explained. Thanks for the effort.
How conveniently you have explained the introduction of PCB....Greatfull
I been wanting to know how these are made ever since I was a kid. Thank You so much 😀
Just amazing explanation
Clearly explained. An excellent video with beautiful animations
A printed circuit board.
Thanks
Thx
Great explanation 🔥🔥🔥
Mind blown. My university was a waste
Take my tuition money 💰
very clear and concise explanation with the animation on point . thanks
Thank you for the excellent video.
Thx man,you don't know how it helps me to start my way to mechatronics
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. 💓
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
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.
Hands down one of the best 👌 videos
Thank you for this excellent explanation, keep going strong with this, kind regards.
Ur awesome. I've been watching your channel since the last 5 years.
thank you!
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
Really brilliant!
This seems fun!
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.
Im gonna wait for the SMT video. Very good job.
Thanks for your videos I learn a alot
I've never thought of it like that.
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.
Your voice is amazing on whole you tube ❤️.
Of course PCB is the 7th installment of the Touhou Project
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..
Best explanation!!
very good video for people to know printed circuit board .
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.

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
Sir you are making great vedios , i really like the way you teach ,you are the best teacher i had ever find on youtube
Well done!
They are like boards where you can have separate inputs and outputs like connect a battery then add electronics
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.
Amazing video. Thank you.
Very informative! Thanks for putting this out. I'll be keeping an eye out for the surface mount version
Thank you , it is very easy to understand now. ❤
Amazing!
Thank you so much
IN FACT simply awesome...very very understandable..similarly like all your videos bro..
Thanks, Sir! Appreciate it
Excellent video, thank you very much
Loved it!.
Wonderful sir🙏🔥🔥
Well explained, cool information,thanks :)

Thanks for such great quality contents 👏👏👏
ITS SHOCKING
Great Information sir.... Excellent ...More valuble..... 👌👌👌👌👌
Very informative!
cant wait for the smt video!
FANTASTIC!!!
Thanks a lot! nice one
perfect video
As an engineering graduate, I would have loved my course years ago if this was easy. I mean, back then, we were forced to drill, weld, and etch manually by hand to the board even though such software exists.

Isn't that the point? That's like a farmer complaining he had to learn that different plants take different water or that his animals have to be fed more than once you cant just type 101010101 and that fixes everything so you need to learn where it comes from what controls those 101010101s and why and how i wish that was a class i could have learned in school i am class of 2011 so I think I was the last class to have to do cursive in 3rd grade but that was in Montana I don know how oregon does it but dude my freshman classes 4 of them where senior classes in Oregon so I had to redo my freshman year cause technically I had no freshman credits just shop JR and SR
@@imfatkid420 simplicity on its application is superior and still the best.
I was crunching hard also on calculus on paper only to realize matlab and excel can do the job for you, like what the f. What sucks here is that I feel like I only am touching the surface of the water for both softwares I've mentioned.
My hand is hurting just reading this. I never designed a pcb, though a schoolmate did. Just thinking about having to etch those lines by hand is just painful, because mine twitches randomly whenever I try to exercise fine motor control.
amazing technology 👍
