THERMAL CONSIDERATION
Thermal management is an important part of the system design. To ensure proper, reliable operation,
sufficient cooling of the power module is needed over the entire temperature range of the module. Natural
convection 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 a 250x300x5mm test Al
plate, under natural convection.

THERMAL DERATING CURVE
The following figure shows the location to monitor the temperature of base plate. Before customer decides to
use this, a thermal evaluation need to be done to make sure the temperature of base plate is lower than that
read from below thermal curves (Figure13 is based on different input voltage).

SOLDERING METHOD
Generally, as the most common mass soldering method for the solder attachment, wave soldering is used for
through-hole power modules and reflow soldering is used for surface-mount ones. 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.

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.
