SOLDERING CONSIDERATIONS

The ALQ25B50 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.
