Using a Soldering Iron
A soldering iron of 18 W or less, using a ceramic heater is recommended. The soldering iron tip diameter
should be 3 mm maximum, and the tip temperature should be 350 C or less. The iron contact time at
each terminal should be limited to 3 seconds. The soldering iron should be applied to the land pattern
next to the module terminal, not directly on the module ceramic substrate.
Example Reflow Soldering Profile
Use rosin flux or a weakly active flux with a chlorine content of 0.2 wt% or less.
