Thanks. I may use JB Weld on my FeCl home etched
segments, just because right now the testing is going
on with no heat sinks at all (mainly because I can't
find any heat sink mounting hardware in my junk box
I have heat sink compound (designed for CPUs) in my
lab now, so all I need is the clips (I want to do it
right with the nice 4 segment board).
