Tack, Bo and thanks you guys.

It takes actually quite some time to administrate approx. 70 letters but to recieve money takes weeks although for 90% it takes only 2-3 days.

I'm glad you like the boards and I'll hope you will use them also. I don't mind pictures :nod:

It was fun to make this board because I haven't made a board in two years privately and one year at work.... that board was rather cool, 475 A, 4 x 140 um copper.

It may be worth mentioning that the heatsinks should be mounted approx. 1 mm above the pcb surface because the are "live" and the groundplane may have an another potential.

Mount the diode at the heatsink

Put a cardboard or something between the heatsink and the pcb.

Solder the heatsink. It's enough to solder with only a tin drop for starter if you of some reason want the remove the heatsink.

Solder the diode.

Remove the cardboard.
