WebEpoxy/resin, soldermask ink) The conductive vias in BGA requires plugged vias. Because solder paste might wick away from the intended pad and flow down into the via, then creating poor or non-existent solder joints during assembly. The diameter of the plugged vias requires to be smaller than 0.5mm. soldermask ink: Epoxy/resin: WebRather than confuse designers and manufacturers by simply specifying that vias must be “plugged” or “filled,” we recommend specifying specific IPC-4761 via type. This helps to make it easier for designers and manufacturers to understand. IPC-4761 specifies only mechanically drilled via types, not laser-drilled micro vias.
