wave and re-flow soldering systems. If hand soldering cannot be avoided, the preferred technique is the utilization of hot

by the difference in coefficients of expansion between solder, chip and substrate. Our terminations are suitable for all

Mildly activated rosin fluxes are preferred. The minimum amount of solder can lead to damage from the stresses caused

Recommended temperature profiles for re-flow soldering in Figure 1.

Products attachment with soldering iron is discouraged due to the inherent process control limitations. In the event that

a soldering iron must be employed the following precautions are recommended.
