Ever wonder what is inside a multilayer PCB?

[iamdarkyoshi]

So I was watching the youtube channel mikeselectricstuff.

 

First, he tore down a very expensive server CPU board.

 

 

Then he wanted to see what was inside the insanely thick PCB. Many of you know that more complex PCBs (like motherboards, graphics cards, etc) have not only traces on the top and bottom layers, but also inside...

 

So he created a setup for milling the PCB away in very thin layers, and he made it so his camera with macro lens would take a photo after each layer was milled out.

 

 

And here was the result:

 

Obviously the tool was not 100% parallel with the PCB, which resulted in some sections being milled out sooner, but the result was really cool!

 

Just thought I would share!

I am not sure if I am sad or very happy to see such an expensive piece of hardware destroyed.

I don't think there is anything expensive.
