PCB manufacturers with heavy copper

Stefanoo · 2nd June 2008, 11:01 PM

Does anyone know of a PCB manufacturer that offers heavy copper (i.e. 3 oz. or heavier) as an option for PCB boards? It seems that most only offer 1oz. copper (or lighter) these days.

Hi Stefano- Around here most board houses will plate the copper to any reasonable thickness. It's a special request and extra cost, and they may complain about going over 2 oz, but it should be possible. I don't know if any of the quick-turn proto houses will do this, so you just have to ask until you find somebody.

I would tell you who does our heavy copper,

but then I'd have to kill you.

My supplier does also 4 oz. copper but on the other hand: Which supplier doesn't do at lest 3 oz.? Non, I'd say.

May I ask what the application is? My was a 300 A device.... continuous

If your application is a regular power amp 2 oz. will do quite nicely.

What if I told him? Would you have to kill the both of us?

thank you guys.
The first link (PCBcart) seems to be very interesting (they just have this initial fee for the first prototype!!!!!)
i will try to quote now from the other ones as well

The application would be for a 100W Class A amplifier with a total bias of 18A.

Nelson......you can try to tell me and then......you can also try to kill me.....but first......please....the info.......eheheh.....the killing
