Default PCB manufacturers with heavy copper

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.

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.

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
