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'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 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.

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

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... Printed. Circuit. Board.... it all makes sense now 🤯

A printed circuit board.

Thank you so much for the information how PCBs are designed from bare board to designed one.

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

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

Really a masterpiece thumbs up

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

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

Y'all's video and animation quality has gotten so good! This may be my favorite you've done. Keep up the great work!

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

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!

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.

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

Very informative! Thanks for putting this out. I'll be keeping an eye out for the surface mount version

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

"Perfect Cherry Blossom"

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

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. 💓

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

Thx man,you don't know how it helps me to start my way to mechatronics

Clearly explained. Thanks for the effort.

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.

Clearly explained. An excellent video with beautiful animations

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

How conveniently you have explained the introduction of PCB....Greatfull

I learned a lot From This Videos. Appreciate Your Hard Work On Such Simple Explanation And This Amazing Animations . 😃

Great content as always, thank you

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

I learned making crude ones with just a pen this copper sheet and that alkaline solution.

very very helpful, I was looking asking this question for years. this video was wonderful

Hands down one of the best 👌 videos

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.

Sir you are making great vedios , i really like the way you teach ,you are the best teacher i had ever find on youtube

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!

Your voice is amazing on whole you tube ❤️.

Just amazing explanation

This video was very well explained and I learned a lot. Thanks

One of the best science Videos on KZfaq, amazing Animation, super simpel and understandable and very good Voice, absolutly amazing work guys👍

Thank you very much sir for this wonderful video

very good video for people to know printed circuit board .

Of course PCB is the 7th installment of the Touhou Project

Thank you for the excellent video.

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.

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.

Im gonna wait for the SMT video. Very good job.

I've never thought of it like that.

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 👍👍👍👍👍👍

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.

Thank you , it is very easy to understand now. ❤

Amazing video...it couldn't be explained better than that.

IN FACT simply awesome...very very understandable..similarly like all your videos bro..

Thanks for your videos I learn a alot

Love from india 🇮🇳🇮🇳🇮🇳

Isse simple or nahi ho sakta Thankyou sir 👍👍👍👍👍

Perfect Cherry Blossom obviously

Thanks for such great quality contents 👏👏👏

Great explanation 👍 Please upload a video about Wafer electronics and IC chips

A great explanation ever I seen😊😘

Its a perfect cherry blossom

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.

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.

pcb--> physics , chemistry, biology for neet

Very nicely explained. Impressive.

Please make video on how the light bulb works

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

Perfect Cherry Blossom

Informative topic Thank you

Perfect cherry blossom

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 KZfaq recommendations

Well explained, cool information,thanks :)

PCB= Perfect Cherry Blossom

I learn more pcb through the video

This seems fun!

Thank you so much

Loved the video and I learned a lot but it was fun

That's the best explanation of PCB ever I watched, Thank you so much sir❤️

Best explanation!!

Perfect Cherry Blossom...

Really brilliant!

勉強なりました、子供の頃から 不思議な回路に興味深く見てましたね ありがとうございます

That's a beautifully made video

very nice 3d video with good explanation.

Please make one series of electricity detail course

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.

Excellent video, thank you very much

Thanks, Sir! Appreciate it

Really clear and fantastic video. Thank you for this!

I got good knowledge through this vdo

thank you!

Great Information sir.... Excellent ...More valuble..... 👌👌👌👌👌
