Webmetallization at substantially reduced rates when compared to 63/37. Solderability is impacted at both the speed of wetting and the degree of spread. Pure tin finishes are the easiest to solder with SAC alloys. While bare copper OSP usually gives the poorest results especially on assemblies that have seen a previous thermal process. Silver Imm. and Web8. jan 2024 · Two key variables in reflow soldering are peak reflow temperature and the time above liquidus (TAL) [ 2 ]. During the reflow process, solder alloys are exposed to peak temperatures that extend 25–50 °C above their melting point to ensure that components are properly fused to the PCB [ 3 ].
