I have PTH cross-section images which show a visible interface between inner
layer foils and the PTH plating. Earlier, similar, board cross-sections show
no discernable interface - the inner layer foil and the barrel plating
appear to be integral.

What should I see when I have an acceptable PWB?



Regards,

Tim Finks
