How much is the price of a gold-plated circuit board better than that of a copper plated one?
Because the minimum 0.05um gold plated thickness, in the case of other factors constant, gold plate prices in general than the expensive 200 yuan / square meters HASL around.
Therefore, the gold plated circuit board can only be compared with the surface treatment such as tin spraying or silver plating, and can not be compared with the copper plating.
Such a comparison is not appropriate, in addition to the negative circuit board production, positive production are usually copper, gold plated copper circuit board will be in production.
