SOLDERING CONSIDERATIONS
The ALQ50 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.
