(Single Output 8^th Brick)
SOLDERING CONSIDERATIONS
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.
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 64 for
the recommended reflow profile.
