SOLDERING CONSIDERATIONS

The AEO and ALO series 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 92 for

the recommended reflow profile.
