Soldering Conditions
Condition for Reflow
Available for Surface Mount Type.
1. Heating method: Double heating method with infrared heater.
2. Temperature measurement: Thermocouple 0.1 to 0.2φ CA(K)or CC(T)at solder joints(copper foil surface). A heat resistive tape

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.

Consult with us for availability of TACT SwitchTM washing.
Prevent flux penetration from the top side of the TACT SwitchTM.
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.
