DESCRIPTION
96.5% Tin / 3.5% Silver, 96% Tin / 4% Silver, and other Tin / Silver Alloys are used for high temperature/high
reliability interconnect applications. Tin/Silver Alloys typically are used in electronic assembly, die attach,
thick film, and applications in which the use of lead is prohibitive. CASTIN, which contains copper,
antimony, silver, and tin, has proven superior in the prevention of the tin intermetallics typically found in high
temp thermocycling. Tin/silver alloys are available in bar, cored wire, solid wire, foil, preforms, powder, and
no-clean, water soluble and rosin solder pastes. Tin/silver no-clean solder pastes pass all Bellcore and IPC
specifications.
