Abstract

Multilayer printed circuit boards 10 with drilled through holes 12 are subjected to a hydrophobic silane bath to seal the tears and cracks 14 in the walls of the drilled through holes to prevent the wicking of plating solution into the walls along these tears and cracks in the fiber of the board resulting from the drilling.
