Surface-Mount Power Module Solder Reflow Recommendation
(continued)
There are several types of SMT reflow technologies currently used in the industry. These surface-mount power
modules can be adequately soldered using natural convection, IR (radiant infrared), convection/IR, or forced con-
vection technologies. The surface-mount power module solder reflow profile is established by accurately measur-
ing the module gull-wing lead surface temperature.
The maximum oven temperature and conveyor speed should prevent the lead temperature from exceeding the
maximum thermal profile limits as shown in Figure 11. The lead temperature during a typical reflow profile is shown
in Figure 12. Failure to observe these maximum lead temperatures and duration may result in permanent damage
to the power module.
Relative temperatures of the module gull-wing leads vary according to many factors, including surrounding compo-
nents, internal paths, and connecting paths. Typically, pin 1 is a good choice for a conservative measurement since
it is usually connected to heavy paths for current conduction which also tend to heat the lead faster. These vari-
ables make it difficult to compare various types of surface-mount modules; however, the unit has been found to be
more robust during temperature profiles compared with other SMT modules available in the industry.
