Soldering
Flow Soldering 260°C maximum for 5 seconds (2 wave solder method)
Infra-red 200°C for a maximum of 30 seconds. Peak of 240°C for a maximum of 5 seconds.
If the solder does not reflow simultaneously under each terminal, there may be a misalignment of the component on the
board. For this reason, it is recommended that the inductor be adhered to the board prior to reflow.
Vapor-phase 215°C for a maximum of 30 seconds.
