Customers are now complaining that we don't have enough gold. What is the most normal gold content of IPG vacuum plating?

Nowadays, high-grade goods are all vacuum plated. IPG is actually tin+gold, but tin is very thick and pure gold is very thin.

In terms of adhesion and wear resistance, vacuum electroplating is superior to water electroplating.

At present, the thickness of high-grade IPG is also very thick, which must be 1 micron. The hardness of tin is very high, which is definitely better than that of water electroplating, no doubt.

Say you don't have enough gold, is your pure gold electroplating layer too thin?
