(from room temperature to 150°C) Solder paste collapse -- ramp up too fast The solvent in flux cannot vapour thoroughly, so the viscosity of the solder paste will be decreased and cause the paste collapse Soldering ball -- ramp up

. The peak temperature is generally determined by the melting temperature of the solder paste and the heat resistance temperature of the PCB substrate and components

. In the reflow section, the peak soldering temperature varies depending on the solder paste used. Generally, the melting point temperature of the solder paste plus 20-40°C is recommended
