How to fix a LDMOS MRFX1K80NR5 to copper heat spreader?

(1/1)

g3vbv:
This amplifier does not have flanges for screwing to the copper heat spreader like others of the LDMOS family.
It looks as if it has an adhesive back, not entirely sure.

langwadt:
you solder it, or clamp it with a strap over the top and deal with the problems of insuring a good connection to the tap
