Hi to all, I am forwarding this question from one of my customers. Thanks in advance. need a good way to plug vias for a cavity design. the plugged vias have to hold up to desmear and PTH chemistries. the vias are small.....about 4 mils....and we can't have any bleed on one side because the wire bond pads are about 3 mils from the vias. been a struggle here....someone must have a better way.
