Failure to observe these instructions may result in the failure of or cause damage to the modules, and can adversely affect long-term reliability. In a conventional Tin/Lead (Sn/Pb) solder process peak reflow Figure 20. Cold Wall Mounting temperatures are limited to less than 235°C. Typically, the eutectic solder melts at 183°C, wets the land, and subsequently wicks the device connection. Sufficient time must be allowed to fuse the plating on the connection to ensure a reliable solder joint. For reliable soldering the solder reflow profile should be April 26, 2016 ©2016 General Electric Company. All rights reserved.

Lead Free Soldering The –Z version of the QHHD019A0B modules are lead-free (Pb-free) and RoHS compliant and are both forward and backward compatible in a Pb-free and a SnPb 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. REFLOW TIME (S) Figure 22. Reflow Profile for Tin/Lead (Sn/Pb) process. o Figure 23. Time Limit Curve Above 205 C for Tin/Lead (Sn/Pb) process Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to GE Board Mounted Power Modules: Soldering and Cleaning Application Note (AN04-001). Layout Considerations The QHHD_225W power module series are low profile in order to be used in fine pitch system card architectures. As such, component clearance between the bottom of the power module and the mounting board is limited. Avoid placing copper areas on the outer layer directly underneath the power module. Also avoid placing via interconnects underneath the power module. April 26, 2016 ©2016 General Electric Company. All rights reserved.
