Re: Is instant glue safe for use in electronics?
I use a 2 part epoxy to hold heatsinks to chips. I prefer Pratley quickset steel, but you can use Araldite quickset white epoxy or pretty much any other 2 part epoxy as well. Clean both surfaces, then sand the heatsink and chip top lightly with 220 grit waterpaper and wipe both sides down afterwards with solvent ( acetone, IPA or even methylated spirits, then mix a little eopxy and apply a thin layer to one surface, then clamp the 2 together until cured. I tend to just mix a match head sized bead of each tube on the top of the chip in the middle with a paper clip, then place the heatsink on it and press down to spread it out to cover the chip. then place a small weight on top and leave for a half hour till cured past gel state. then you preferably leave for 24 hours or gently heat to 70c to hasten the cure. Generally you get a 30C drop in chip temperature, using a small heatsink with fins about 20mm tall covering the entire chip top. Common source of the heatsinks are old motherboards, taking the north bridge, south bridge and memory heatsinks.
