What is a PCB?

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've read hundred time about single multiple layer PCB each with different etching Technic but animation makes is look even more easy to understand

Clearly explained. An excellent video with beautiful animations.

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.

I am waiting for your next video on SMD PCB.

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.

25 years ago, as an engineering student, we designed our own pcb’s and “manufactured” our own self-made radios, and other electronic equipment

This came from my recommended after watching a bunch of touhou videos, and I get the feeling YouTube fully believes the answer is "Perfect Cherry Blossom"

[nagrajangadi]

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!

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

[hazemomar]

Sooo thankfull to all of you
Sending my love from egypt ❤️

[jfrank]

This is brilliant....hope to see televised production soon

[ikmax]

Simple but perfectly explained The PCB manufacturing! Keep it up Team :)

[jhatnik]

I been wanting to know how these are made ever since I was a kid. Thank You so much 😀

[sangram.methry]

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. 💓

[abgrafix]

very clear and concise explanation with the animation on point . thanks

[Angel_Gomez]

This is a weird way to describe Perfect Cherry Blossom but good video regardless 👍

[dy]

Ur awesome. I've been watching your channel since the last 5 years.

[saskiavanhoutert]

Thank you for this excellent explanation, keep going strong with this, kind regards.
