Small copper plate to replace thermal tape?

Problem: Too big, too thick by 1.5mm, and needs sanding (for which I do not have the resources)

I am looking for a plate that is about 1.5mm thick and 0.25"x0.25" to replace a piece of thermal tape on my lappy's chipset. :\

call a precision machine shop. Any shop worth their salt should be able to bang something like that out for a small fee with some tight tolerances

I'm assuming the copper plate is needed to reproduce the thickness of the thermal tape, and nothing else.

You'll still want a thermal interface material - a paste. That tape was serving 3 functions then: spacing, thermal interface, and adhesion.

Sorry for restating the obvious...

laptop has a peltier cooler? ok. if not, I don't get why you would use this. the top of the cpu is probably copper and the bottom of the heatsink is likely to be copper also. you would need to put 2 layers of paste. but maybe I don't know what I am talking about.

He needs a gap filler. Apparently OP is replacing a thermal pad with the much more thermally effecient "normal" thermal grease and needs to fill up the thickness. Yes he will need two layers of grease/paste but overall it will still be a lot better than the thermal pads which suck and are very expensive and hard to find.


OP. 1.5mm =~ .059inchs =~ .060 inches a very standard sheet metal thickness. This should not be hard to find from any sheetmetal source. Since you mentioned mm I assume you are not in USA ?

Try google "sheet copper" etc.

Brass would work well also and might be easier to find. Sheet brass widely available in a mulititude of thickness for use as shim stock.

Pick up copper sheetmetal of the appropriate size (or buy several thicknesses in the ballpark range and the test yourself) locally or online. Cut to size with snips, a jigsaw, whatever. Score whatever coating they put on it off with sandpaper (600 grit is good) and then apply your favorite TIM to each side. I did this on my old Dell 9300 and it works like a charm.

What resources are you missing that you can't do this?
