8. SOLDERING AND MOUNTING :

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

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.

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

Mildly activated rosin fluxes are preferred. 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 air soldering tools.

8-1.1 Solder Re-flow :

f) Limit soldering time to 4-5 secs.

d) 1.0mm tip diameter (max)

b) 355° C tip temperature (max)

c) Never contact the ceramic with the iron tip

8-1.2 Soldering Iron (Figure 2) :

a) Preheat circuit and products to 150° C.
