Q. What is the best way to strip immersion gold from electronic packages? A.G.

 

A. Your best bet is to use a proprietary formulation for stripping the gold. These products are designed to dissolve the gold and protect any copper and nickel that may be on the surface of the parts. You can find vendors of stripping solutions at Products Finishing Supplier Database.

You should be aware that immersion golds have different characteristics depending on what the base metal is and how it has been prepared. The porosity of the deposit, the thickness of the deposit and the amount of alloying material in the deposit all will affect the rate of removal.
