I have been installing parts on my NTI Newton board and I just put on the LM323K. I haven't powered it up yet, because I am unsure how to know if the thermal grease or the heatsink will cause a short. Should I put some type of insulation around the pins on the regular? Is this just one of those things where it works or you fry it? The holes in the lm323k are smaller than the heatsink, so trusting those to take up the slack and center it seems risky too. Maybe this isnt a big deal, but I have poured a considerable amount of time and money into this board and it seems like I should ask if anyone else has had a problem at this point.
