Hello, I am wondering about a few mounting issues for transistors, resistors and heat spreader bars.
I am planning on mounting some filament regulator transistors (Coleman V9) to an aluminum bar 3/8" thick that will then bolt to an aluminum chassis. The transistors are plastic bodied. I will also be mounting an aluminum bodied chassis mount type resistor to the chassis.
Is there a need for thermal paste on these parts before bolting them down? They do not need to be electrically insulated I know.
Same question for the spreader bar to the aluminum chassis. Is a thermal past needed?
I am NOT planning on grinding the surfaces - just running the extrusions over some abrasive paper on a glass sheet. I also have enough Keratherm to use if needed. None of these parts are running over 100° F on a breadboarded amp with cobbled together thermal management techniques. (Bolted to some punched aluminum panels around 4 x 6 inches).
Thanks in advance.
