"How to remove the oxide layer from Sn/Ag surface?"



2005

I tried 10% HCL, and noticed that some black dots created on the surface, and I am afraid there are some reaction there.
Could anybody recommend a way to clean the Sn/Ag surface to remove the oxide layer? or any place I can find the methods?
Thank you!

Not enough info to give you a good answer. What is the material you are working with. How big are the parts? How many?

Jane:

Do you use inhibited HCl (muriatic acid)? If not, HCl will be very aggressive on most metallic surfaces and will probably over-etch your parts.

Dear Jane,
I suppose you mean silver plating over tin, you can use a cyanide dip as a pretreatment to remove the sulfuric layer not oxide :).
