Phil,
        rather than plating the through holes, why not fill with a screen
print/ thermal cure conductive? The effectiveness of this method may depend
on hole diameter & panel thickness.....
just a thought.

Subject: [TN] Copper Plating Aluminum


All

Some designer has called out a plated-thru PC board that has copper layers
and aluminum cores joined by plated thru copper holes.  I am aware of two
lousy methods that have been used.  One is to use electroless nickle instead
of electroless copper to give a metallic coating in the holes prep the
holes.
 A zincate process precedes the electroess nickel.  The second is to use a
board that has been zincated and use pryo copper asa a plating solution.

Does anybody have any other less difficult magical solution(s)

Thanks
Phil Hinton
