To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Conduction cooling is usually the dominant mode of heat transfer. Thermal Testing Setup The following figure shows the testing setup in which the power mudule is mounted on an Al plate and was cooled by cooling liquid. Figure 12: Thermal test setup DS_PACSR24021_07142020 E-mail: dcdc@deltaww.com http://www.deltaww.com/dcdc P7 THERMAL DERATING CURVE The following figure shows the location to monitor the temperature of the module’s baseplate. The baseplate temperature in thermal curve is a reference for customer to make thermal evaluation and make sure the module is operated under allowable temperature. (Thermal curves shown in Figure14 are based on different input voltage).

Delta recommended soldering methods and process parameters are provided in this document for solder attachment of power modules onto system board. SAC305 is the suggested lead-free solder alloy for all soldering methods. The soldering temperature profile presented in this document is based on SAC305 solder alloy. Reflow soldering is not a suggested method for through-hole power modules due to many process and reliability concerns. If you have this kind of application requirement, please contact Delta sales or FAE for further confirmation. Wave Soldering (Lead-free) Delta’s power modules are designed to be compatible with single-wave or dual wave soldering. The suggested soldering process must keep the power module’s internal temperature below the critical temperature of 217℃ continuously. The recommended wave-soldering profile is shown below: Note: The temperature is measured on solder joint of pins of power module. The typical recommended (for double-side circuit board) preheat temperature is 115+/-10℃ on the top side (component side) of the circuit board. The circuit-board bottom-side preheat temperature is typically recommended to be greater than 135℃ and preferably within 100℃ of the solder-wave temperature. A maximum recommended preheat up rate is 3℃ /s. A maximum recommended solder pot temperature is 255+/-5℃ with solder-wave dwell time of 3~6 seconds. The cooling down rate is typically recommended to be 6℃/s maximum. DS_PACSR24021_07142020 E-mail: dcdc@deltaww.com http://www.deltaww.com/dcdc P10 Hand Soldering (Lead Free) Hand soldering is the least preferred method because the amount of solder applied, the time the soldering iron is held on the joint, the temperature of the iron, and the temperature of the solder joint are variable. The recommended hand soldering guideline is listed in Table below. The suggested soldering process must keep the power module’s internal temperature below the critical temperature of 217℃ continuously.
