[@kainblack5041]

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.

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.

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

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.

Yah. An practical pcb is very complex and the traces are so designed in cpmpact space so that minimum gets wasted.

I wouldn't say THT technology is obsolete, but rather less prominent. Since this board is so simple, it does not have vias, probably the most important part of modern day PCB's.

Is the "printed conducting coper circuit" right from 0:48 to 1:04 right? The copper forms a "short" circuit?

[@stephenolan5539]

A "short" circuit means an unintended connection. Although to be honest if I am checking for opens and the circuit is good, I will call it short. Although technically I should call it connected.

If copper foil is used initially, won't it cause short circuiting for through hole PCB

[@EssayWriting-du3pw]

I understand now, so we etch away the copper foil to remain with the traces

[@nhgjl9094]

it was good

[@ReadTheShrill]

You completely glossed over through-hole inserts. Every drilled hole has a ring inserted into it, to bridge the gap between each side of the PCB. Without them, the traces that run to holes would not be electrically connected from one side of the board to the other, and the board would be useless.

[@TTM77]

It wouldn't be useless and not needed if the board is only one side. And the technical term is "layer" because you can have more than just top and bottom layers.
