Subject: [TN] Via in Pad: Filling of vias using silver epoxy!?!?
Guys,
I am dealing with high frequency board which is 25 mil thick and made of
Rogers material. The other side is totally exposed copper. How should I
handle as there via in pads (VIP)? I have heard about filling the vias
using silver epoxy and then plating it over. Can someone shed some more
light?
