WebThe relationship between reflow profile parameters (soak temperature and soak time, reflow temperature and reflow time, cooling rate) and shear performance of Sn3.0Ag0.5Cu/Cu solder joint was investigated. It was found that soak time, reflow temperature and cooling rate had significant influence on the shear performance of Sn3.0Ag0.5Cu/Cu. Adequately … WebThe soak temperature is controlled within a tight range (see Figure 2) for a specified time. This “plateau” in the reflow profile allows the thermal gradient across the PCB to … A high minimum reflow time also provides a margin of safety against oven temperature changes. The wetting time ideally stays below 60 seconds above liquidus. Additional time above liquidus may cause excessive intermetallic growth, which can lead to joint brittleness.
