Note
1. The above temperature shall be measured on the mounting surface of a PC board. There are cases where the PC
board's temperature greatly differs from that of the switch, depending on the material, size, thickness of PC boards
and others. The above-stated conditions shall also apply to switch surface temperatures.
2. Soldering conditions differ depending on reflow soldering machines. Prior verification of soldering condition is
highly recommended.

.
Switch terminals and a PC board should not be coated with flux prior to soldering.
The second soldering should be done after the switch is stable with normal temperature.
Use the flux with a specific gravity of min 0.81.
