Mildly activated rosin fluxes are preferred. 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. Our 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
