The alloy that fit the melting temperature that I need is the Sn96.5Ag3.5 alloy(Tm=220C). I aware of the electrical migration phenomena correlate with the use of silver existence alloy. I would like to know if anyone had experience any problem of electrical migration when using this alloy or other alloy that consist silver and how it was recognized. Thanks In Advance, Tamir. >> Tamir, I am very familiar with this alloy and have used it extensively in many applications. I would not be concerned about migration with this alloy.
