Figure 43B. Mechanical Outline – SMT (Solder Ball) Termination.
SOLDERING CONSIDERATIONS
The through hole terminated converters are
compatible with standard wave soldering techniques.
When wave soldering, the converter pins should be
preheated for 20-30 sec at 110
°
C and wave soldered
at 260
°
C for less than 10 sec.
When hand soldering, the iron temperature should be
maintained at 425
°
C and applied to the converter pins
for less than 5 seconds. Longer exposure can cause
internal damage to the converter. Cleaning can be
performed with cleaning solvent IPA or with water.
For SMT terminated modules, refer to Figure 44 for
the recommended reflow profile.
