Seeking advice on Pill/Heat Sink to be constructed from 1/8" x 40mm dia. copper plate

Thanks for your post, wight. I started another thread because I felt my original thread was getting close to running its course. I figured a new thread about the pill assembly alone would allow a “fresh start” and possibly attract other opinions.

Can you (anyone else, feel free to chime in) recommend a particular brand of solder paste with high thermal conductivity?

I will address your questions about the “stock switch” assembly soon, back on my previous thread.
