Removing Solder Pins from Heatsinks

luvdunhill · 4th April 2008, 09:26 PM

is there any way to extract the pins from these heatsinks:

I'd like to tap the heat sinks so I can install a longer screw.. Digi-key lists these as "bolt-on" (part number HS380-ND), but I'm assuming it's a mistake and they have solder pins, or there is some way to remove them. The pins seem to be in there real good

They're in there real good so they don't come out! But, they were pressed in, so they should press out with enough force. Either grab the bottom with Vise-Grips(TM) and lever them out, or some of those extrusions have the pins in channels, and you can drive them out from the other side using a hard steel pin.

Hint : steel has 1/2 the thermal expansion factor of aluminum.

Yep. That works. I use an allen wrench.

hm, i tried heating them up with a heatgun for stripping paint, no luck. Once they were really hot, I hit them with hammer to if they would even move (albeit in the wrong direction) and they didn't. Same with driving them back through the other side with a pin. The pins are knurled in two places...

It is more simple to use them upside down and drill a new hole for the mounting of the component.
good luck, Loek

Or use (insert favorite metal cutting tool) to cut the things off.
