What is meant by 10 micron glod plating? is it very good or just average?

Answer 1

Gold plating is when gold metal is deposited on top of a less expensive metal as the base. 10 microns refers to the thickness of this gold layer. A micron is 1 millionth of an inch, so you can judge yourself how much quality there is in a gold layer with 10 microns of thickness.
