RE: [TCML] Soldering SISG heat sinks
Thanks guys... Much appreciate the benefit of your experience!
Will epoxy them for mechanical stability and hopefully complete the
conversion over to SISG in time for first light tonight....;- )
Have a great Halloween!

I'm sure you had read the TCML before embarking on this project,
a reminder here's my post from February::
Here's my SISG tips:
1. "Maxclips" for mounting the IGBTs work fine. I mounted the heatsinks
the board, then put compound on the IGBTs and heatsinks, then dropped
into place on the board, then screwed on the clip, then went back and
soldered the IGBTs in. I figured this way, everything was in a happy
position before it got soldered solid.
4. I put everything together with a 140W soldering gun. I never
the "use a low-wattage iron with heat-sensitive components" theory. I
luck blasting it quickly, before the heat has time to spread up the
