Spongy SMD regulator heat sink?

[luvdunhill]

Hey guys!

I have a small SMD regulator that needs a bit of heat sinking. It is about 1/8" away from the plastic housing, but at this point it is slightly curved. Is there some sort of spongy heat transfer material out there that might be appropriate in this situation?

Can you fashion a small piece of metal (preferably aluminum or copper) to the package with double sided tape or super glue? That would be better than any kind of spongy, non-metal material.

I guess I was wanting to couple it to the case, but it's plastic so maybe that won't do all that good, but in my head I was thinking it would work better than just a piece of metal... it's worth a try though.

Fujipoly has gap filler pads to transfer heat.

look for a low pressure material with a high W/mK rating and were possible try to use the thinnest material that will still conform to your component.

The plastic box however is you enemy, you could use the material only as a medium for coupling the heat to another more suitable heat spreader or heat sink.
