SN100C P602 is completely halogen-free, which means there are no intentional halogens of F, Cl, Br or even I hidden in the chemistry. The SN100C alloy delivers a Silver-free stable microstructure in an alloy that can accommodate the long-term cyclic strains and impact strains to which a solder joint can be subjected.
The lead-free paste has smooth bright fillets with few shrinkage defects and a stable microstructure with minimal growth of the interfacial intermetallic, resulting in highly reliable solder joints. SN100C provides excellent printing and reflow in fine-pitch circuitry, low hot and cold slump, and good coalescence and wetting with no solder balls.
