Example of Reflow Soldering Condition
1. Heating method: Double heating method with infrared heater.
2. Temperature measurement: Thermocouple 0.1 to 0.2φCA（K）or CC（T）at soldering portion（copper foil surface）. A heat resisting tape
should be used for fixed measurement.

1. The condition mentioned above is the temperature 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 PC board's material, size,
thickness, etc. 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.
