Hi,
We have left our 60W Offline Flyback SMPS running for the weekend at 20W. I have just remembered that I forgot to solder the FET heatsink pin to the PCB. ..The TO220 FET hangs upside down in the enclosure, therefore, the heatsink will be weighing down on the legs of the TO220 FET which are soldered into the PCB…….do you think the FET legs may disconnect from the silicon inside the TO220 package, due to the weight of the heatsink? The heatsink is part number SK 469 35 STS BY Fischer.com…..
