For further information please contact your local GE Technical Sales Representative. Reflow Soldering Information These power modules are large mass, low thermal resistance devices and typically heat up slower than other SMT components. It is recommended that the customer review data sheets in order to customize the solder reflow profile for each application board assembly. The following instructions must be observed when SMT soldering these units. Failure to observe these instructions may result in the failure of or cause damage to the modules, and can adversely affect long-term reliability. There are several types of SMT reflow technologies currently used in the industry. These surface mount power modules can be reliably soldered using natural forced convection, IR (radiant infrared), or a combination of convection/IR. The recommended linear reflow profile using Sn/Pb solder is shown in Figure 20 and 21. For reliable soldering the solder reflow profile should be established by accurately measuring the modules CP connector temperatures. REFLOW TIME (S) Figure 19. Recommended Reflow Profile for Sn/Pb solder. TIME LIMIT (S) Figure 20. Time Limit, Tlim, Curve Above 205oC Reflow . Lead Free Soldering The –Z version SMT modules of the SSTW series are lead-free (Pb-free) and RoHS compliant and are compatible in a Pb-free soldering process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability. Figure 21.
