9. SOLDERING AND MOUNTING :

c) Never contact the ceramic with the iron tip

e) Use a 20 watt soldering iron with tip diameter of 1.0mm

d) 1.0mm tip diameter (max)

f) Limit soldering time to 4-5 secs.

9-2.2 Soldering Iron (Figure 2) :

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

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

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

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

a) Preheat circuit and products to 150° C.
