Gertbot Heatsink Thermal Glue/Paste

duanewhitney33
duanewhitney33 over 8 years ago

I just purchased a Gertbot board.  On inspection, I noticed quite a bit of excess thermal glue/paste on the heatsinks.   Do I need to worry about shorts, or is the paste insulating?  I also noticed that one of the heatsinks is only a hair away from one of the onboard caps solder joint.  I'm wondering if it might be best to remove the heatsink and re-attach it in a better position.  Not sure what to use to remove it and what to use as a paste/glue so I don't create more problems.  I haven't tried the board yet to avoid shorts.  Thanks!

    Hi Duane. The paste itself is thermally conductive, but not electrically, so you'd be fine in that respect.

     

    But the heat sink itself will be metal, of course, so I might be tempted to try and re-position that a little bit, if you can?

    How strong is the glue on these? Some glues are fine and come away with carefully applied force to try to ease one side up, but I have had heatsinks glued on with stuff that is impossible to break and in these cases it's possible to accidentally pull the top off the IC or the IC off the board and ruin your day..... Give it a go but be careful!
