STANNOLOY alloys are soft solders according to an in-house specification with significantly lower impurities in comparison with alloys which are manufactured according to S-Sn60Pb40E or S-Sn63Pb37E (ISO 9453:2006). STANNOLOY alloys are manufactured from ultra pure metals. The non-metallic impurities are removed by an additional refining process.
- Better wetting characteristics even for solder bath temperatures which are somewhat below the usual operating temperature -> reduces the risk of damage to heat-sensitive components.
- STANNOLOY is particularly used for wave soldering of SMD populated PCBs because very low viscosity, large mounting density, reduced solder application, minimal metal impurities and oxide content are particularly important here.
- STANNOLOY achieves clean, well-formed solder joints. The number of soldering defects is minimised due to the excellent flow characteristics of STANNOLOY.
STANNOLOY alloys are preferably used in wave solder machines which are operated with protective gas.
