When wave soldering, the converter pins should be preheated for 20-30 sec at 110 °C and wave soldered at 260°C for less than 10 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. For SMT terminated modules, refer to Figure 92 for the recommended reflow profile.
