I was considering making a copper heat spreader to mate say a P7 with an aluminum heatsink. I get the impression that P7 thermal board is not as low as it could be because it's electrically insulating and it doesn't even need to be electrically insulating.
I do have some electroless Bright Tin plate used for PCBs. Would this be helpful? If moisture does get in it will prevent corrosion. I don't expect it'd have any effect on the thermal resistance? Is there going to be galvanic corrosion from the tin-to-aluminum surface? Would it be better than the copper-to-aluminum situation?
