Is there a real reason to solder heatsink pins onto your PCB other than stability? As the heatsink heats up, would this potentially heat up a small area on the PCB surrounding the soldered heatsink pins?
I've been using a small heatsink on a TO-220 device that I just use a 4-40 screw and nut, but I will be using a larger heatsink now that comes in 2 models- one with solderable pins and one without.
I'm trying to figure out if there is a reason why I should choose the model with the solderable pins.
