Ralph,
I have some info on a screenable polymer thick film paste for pluging vias
for thermal conductivity. I have never used the materilal. It is from
DuPont Electronoc Materials. Thermal conductivity is spec'd at 5.23W/m/K.
CB100 CONDUCTIVE VIA PLUG
If your interested send me your fax number.

Subject: [TN] Thermallly conductive PWB materials
Dear PWB fab guys,
Can you provide any news, good or bad, on material used in boards to
help move heat away from hot parts? We have tried the standard methods
of leaving unused copper in the board rather than etching it away, and
using thermal pads under the parts, but my designers think they need
more thermal conduction through the pwb. If anyone has any experience
with the thermally conductive pre-pregs, or any other similar material,
I would appreciate your thoughts.
thanks
