Copper coined PCB

[nikhil2402]

Hi Everyone,

I am wondering someone here designed a copper coined pcb. I tried looking around and I dont really understand this technology. If someone has better overview of this, can you share the concept with images and so on. Additionally, how do I set it up in Altium designer?

Looking forward to your help

I didn't know something like this is possible. I can't really help as I have never used it, but it is interesting.

PS: For everyone who has never heard about copper coin in PCB, here is more info:
"The concept is based on getting a copper coin press fit into a premade cutout in the board right under an area that is identified as a hot spot – MOSFET pad for example."

Yes new thing for me as well. Apparently, such a thing is very useful heat dissipation when you are working with really high power designs.

The simplest design that I have thought about is to insert a hole below the IC where the thermal pad exists. This is plated through hole all the way down to bottom layers. We then ask the PCB manufacturer to insert a copper coin in this region. However, this is a simple copper coin arrangement but there exists many different flavors.

PS: Its good thing to first check whether the manufacturer has the capability to do this.
