Phase 1 - Pre-Heat
During the Pre-Heat phase, the solder paste dries and its more volatile ingredients evaporate. The component body temperature should be brought at a controlled rate from room temperature (approximately 25℃) to 175±25℃. The maximum rate of change of temperature during the Pre-Heat phase should be less than +3℃/s to avoid component damage due to thermal stress.
Phase 2 - Flux Activation
During the Flux Activation phase the flux component of the solder paste has time to micro-each and clean the metallized pads and component leads in preparation for solder reflow. The component body temperature should be maintained at 175±25℃for 60~180s.
Phase 3 - Reflow
During the reflow phase the component lead temperature is brought to above the melting point of the solder alloy in use and held long enough to ensure complete wetting of all surfaces. For the industry norm solder alloy Sn96.5 Ag3.0 Cu0.5 this melting temperature is 219. The component
℃ lead temperature should be maintained above 219℃for 60 to 150s. The maximum rate of change of temperature during the reflow phase should be less than +3℃/s to avoid component damage due to thermal stress. The maximum component body lead temperature promised for SMT devices during the reflow phase is 245℃for less than 10s.
Phase 4 - Cooling
During the cooling phase the molten solder connections are allowed to slowly re-solidify into strong solder fillets. A fast cooling rate reduces the grain size of the inter-metallic compounds and strengthens the solder joints. However, due to the risk of thermal shock and solder joint brittleness, the maximum rate of change
℃
of temperature during the cooling phase should be less than -6/s.
