I'm still trying to figure out why epoxy was used to hold a SMD on the
board? thermal-conductive epoxy?

I also can't see epoxy having that tight a grip on the PCB,that it

wouldn't
break loose before the SMD package broke. must be some damn good

epoxy,wish
I knew who makes it and where to get it!


Belt and braces , to take the mechanical strain off the solder? To scrape
back the epoxy to a clean board , the action of a soldering iron tip on it,
was like the normal reaction of solder-iron heat to epoxy, goes powdery .
Perhaps its bright red as a warning


Red? Sounds like somebody used Loctite Red, (permanent liquid gasket
compund).
