Or www.digikey.com and search for BER161-ND.

I think the cheaper alternatives are thermally conductive adhesives or
compounds like thermal grease.
Well..maybe not.. One Loctite thermally conductive adhesive cost me
$125CAN in the smallest quantity available.
The BER161 4"x4" is @~$12.00CAD.

Depends on the application. if low thermal resistance is required, better
to go with the white stuff as think as possible. If its not so criticla but
you need some thermal contact to keep moderately warm components cooler and
you don't want the tight tolerance issued of chassis mounted components, it
is pretty good.

We use it on the opposite side of some D2PAC mosfets. Peppered the board
with thermal vias and put the pad under the board. 10 degrees C lower
temperature than without.

 

It all depends on what you want to use it for and what you want to
know... It's Berquist GAP-PAD 1500 thermally conductive material.

Tim Williams a écrit :

I used that to cool a low inductance 1mR PCB shunt (20x10mm) carrying up
to 150A and dissipating up to 22W!

Worked like a charm, but this reminds me something: don't make the same
mistake the prod guys did. When the board went to prod they forgot to
peel off the protective sheets on the first one: pzzzt, pofff... three
fully mounted 12 layers 20x15" ($3k each) going to dump at final test.

 

Comment in what way ?

What do you want to do with it ?

My brevity fails me...

To insulate two heat spreaders, 1.5 x 3" copper. Alternately, just
insulating a pair of TO-247's, but I get the feeling 4.5 in^2 is a somewhat
better footprint, besides which I already have it set up that way.

White goop would be fine, except that I need to stand off 360V minimum (the
transistors are rated for 600V, so more than that would be good).

P.S. Oops, looks like I CTRL+R'd this post a few days ago, instead of
CTRL+G...
