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. 3. Temperature profile 300 200 100 A max. B D E C Time (s) F max. Room temperature Temperature (˚C ) 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. Notes 300 200 100 A max. B C Time (s) 25s max.E max. D max.
