The AEO (baseplate) series converters are compatible
with standard wave soldering techniques. When wave
soldering, the converter pins should be preheated for
20-30 seconds at 110°C and wave soldered at 260°C
for less than 10 seconds.
REFLOW
ZONE
< 80 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.
