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

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

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