Hi Francois,

As Joe put it lay the transistors flat on heat-sink and bend pins up . This will be an art. Attached is a sample. You need to watch the clearance of the bolt head from the PCB.

Have fun

1. Place unpopulated PCB on heat-sink.
2. Use ink to mark the lead positions on the heat-sink.
3. Place transistors on heat sink with the pins bent straight up
4. Align the transistors leads with the ink marks
5. Use ink to mark the mounting holes of each transistor
6. Drill mounting holes

The link to the BoM appears to have changed (due to thread moving?). Be grateful for another link as my mac seems to have lost (which is my fault) the original download!!

Can you perhaps point me in the right direction? Mainly interested in BoM for latest boards.

Many thanks,


EDIT: just found the latest revision in .pdf format, but it will not open (for me) on Mac 10.7.5.
