Wire-wound Type Power Inductor SCWL252012XXXXQ Series Soldering and Mounting Soldering Mildly activated rosin fluxes are preferred. SOCAY 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. Solder re-flow Recommended temperature profiles for re-flow soldering in Figure 1. Solder Iron (Figure 2): Products attachment with a 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. u Preheat circuit and products to 150 ℃ u Never contact the ceramic with the iron tip u Use a 20 watt soldering iron with tip diam eter of 1.0mm u 355 ℃ tip temperature (max) u 1.0mm tip diameter (max) u Limit soldering time to 4~5 sec.
