Default Group Buy: Rectifier bridge with 4-layer pcb

I have made some rectifier bridge pcb's made with 4 layers, 70 um, 2 oz. copper and gold pads. The colour is yellow but this is only a test. I was curious how yellow solder mask looked like. The group buy order will be red.

As you can see I have five holes for the diodes, one footprint for TO218/247 and one for TO220. The connections is spade terminals or big holes for 6 sqmm, AWG9 which will satisfy most people I think. The board has also snubbers.

The wiki page is down at the moment so in the meantime I'll put up a temporarily at my personal website.

The price will be attractive but it all depends of how many pcb's I will order.

Excuse my perhaps dumb question, but: why do you need four layers for a bridge rectifier?

I chose four layers because I want the heatsink (at right) to be insulated and have enough of copper for hand 30 A diodes, making the pcb really heavy duty.

They should be OK but soon I will know for sure. I'll also hope that the wiki will be up soon.
