The difference between electroplating plug hole and resin plug hole

1. Surface difference:

The electroplating plug hole is filled by copper plating, and the inner surface of the hole is full of metal. The resin plug hole is filled with epoxy resin after copper plating on the hole wall, and finally copper plating on the resin surface. The effect is that the hole can be conducted, and there is no dent on the surface, which does not affect the welding.

2. The process is different

Electroplating plug hole is to fill the through hole directly through electroplating, which has no gap and is good for welding, but it has high requirements for process capability, which can not be done by general manufacturers. Resin plug hole is filled with epoxy resin to fill the hole after copper plating on the hole wall, and finally copper plating on the surface. The effect is like no hole, which is good for welding.

3. Different prices:

The oxidation resistance of electroplating is good, but the process requirements are high and the price is expensive; the insulation of resin is good and the price is cheap.
