        Via plugged with resin can solve the problems that green oil plug holes can't solve, but the characteristics of the resin used in this process need to overcome many difficulties in production in order to obtain good quality resin products. So why do PCB   vias plugged with resin ?   Traditional BGA may make vias between pads to the back for routing.  If the BGA is too dense, it is impossible to route from the  vias   to the back, but you can drill directly from the pad to   other layers   for routing , then plug the  via s with resin, and plate copper to form the pad.   If only holes are made on the pads without resin plug holes,  it will easily lead to short circuit on the back and virtual   soldering   on the front.     The PCB vias plugged with resin process includes drilling, electroplating, plugging, baking, and grinding. The holes are drilled and copper plated, then the resin is plug...
