which characteristics? An alloy with similar melting points, wetting, shear force, reliabilities, etc. Indium has an article about 77.2Sn/20.0In/2.8Ag, but was wondering is there any other out there.

Hi, I agree with everyone else talk to the Mfg and ask for their recommended profiles. They should know the heating and the cooling profiles. If you really want to do this yourself you are going to have to run several experiments to determine just

Check out the web sites of the major solder manufacturers. From a quick glance most of the pastes around that temperature range have problems with Zn content and may not be available as pastes???? Depending on your application, some of the lower melt

It probably depends on the Silver content. We are also using Sn62Pb36Ag2. The paste manufacturer told us that the reason for the small silver content was so that it could wet better to the lead-free component and board finishes bearing silver.
