Snubber board for IXYS SOT-227B diodes

[coolnose]

Hi All,

I have built a couple of amps in the past using either the GPBC block type diodes or the PSU V3 diodes from the store.

I wanted something "fancier" than the block rectifier without going through the hassle (and cost of needed parts) to assemble the diode boards from the store.

So I cobbled together a small prototype board as attached mainly to confirm the footprint etc.

The SOT-227B should fit the perforated base plate of the shop chassis.

I have attached some pics that should be pretty self explanatory.

The boards are 26x39mm , 1,6mm thick and 1oz copper only on the test run and admittedly the resistor positionning is somewhat dodgy, I got lost in the 0,01mm grid in Kicad...

In someone is interested in a couple of boards for a built and willing to give me some feedback I'd happily send a couple of those out.

If this raises enough interest I could offer a group buy (of slighly modified boards in 2mm and 2oz) incl. the IXYS diodes for around 50% of the price at the major distributors (fellow DIYer has lifetime stash of those for whatever reason).

Looking forward to you thoughts.

EDIT: Pictures comming in 2nd post, forgot to crop them...

Great job, congratulations!

Thanks Mark for those kind words!

I mentionned your thread for the Quasimodo, I hope that's fine with you.

Sure. As far as I'm concerned, once something is posted to diyAudio, it has become public domain and anybody can do anything they want with it.
