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
