Thanks Jim

Did you do this extra plating selectively. Or did you just overplate the
whole PCB.  Someone else mentioned the dupont product we are trying to
get our vendor to look at it.
Thanks
John Foster

John, We've looked into the sand thing a while ago, and found that just by
increasing the copper plating in the hole to 2 mils will give you far better
thermal performance than any thermally conductive epoxy for hole fill.

        Hello, I am new to this listserver. I must say that it is very
        informative. I wish I had known of it long ago.

        I have a question about via plugging.  Right now
        our board vendor is doing our via plugs with
        I guess with a standard epoxy. We are trying
        to find a solution that would give us a much
        better thermal performance.

        We are looking at silver epoxy and this
        material from Dupont.  Does anyone know of
        some material that would give us a really good
        thermal performance. We are in a commercial
        environment. So the material does not have to
        meet industrial specs.

        Any input on this matter would be greatly '
        appreciated.

        Thank You

        John Foster
