Example of Reflow Soldering Condition
1. Heating method: Double heating method with infrared heater.
2. Temperature measurement: Thermocouple φ0.1 to 0.2 CA （K） or CC （T） at soldering portion（copper foil surface）.
　 A heat resisting tape should be used for fixed measurement.

Pre-heating
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.
