The minimum amount of solder can lead to damage from the stresses caused by the difference in coefficients of expansion between solder, chip and substrate. The terminations are suitable for all wave and re-flow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot air soldering tools. Recommended temperature profiles for re-flow soldering in Figure 1. Products attachment with a soldering iron is discouraged due to the inherent process control limitations.
