We are once again exploring the possibility of changing a few board designs
to Aluminum Cores instead of Copper Cores for weight savings.  The Aluminum
Core designs to date have non-active Cores.

I would like to know:

Does anyone have a current board design that requires via holes to be plated
to an aluminum core?

Is there a viable, repeatable process for plating through the holes
including the aluminum?
