Heating method: Double heating method with infrared heater. 2. Temperature measurement: Thermocouple 0.1 to 0.2φ CA（K）or CC（T）at soldering portion（copper foil surface）. A heat resisting tape should be used for fixed measurement. 3.

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. You are requested to verify the soldering conditions thoroughly beforehand.
