Technical Reference Notes
ALO25F24
(Single Output 8^th Brick)
SOLDERING CONSIDERATIONS
The ALO25F24 converter is 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 16 for
the recommended reflow profile.
