1. Heating method: Double heating method with infrared heater.
2. Temperature measurement: Thermocouple 0.1 to 0.2φCA（K）or CC（T）at solder joints（copper foil surface）. A heat resistive tape
should be used to fix thermocouple.

Items
1. Consult with us for availability of TACT SwitchTM washing.
2. Prevent flux penetration from the top side of the TACT SwitchTM.
3. Switch terminals and a PC board should not be coated with flux prior to soldering.
4. The second soldering should be done after the switch is stable with normal temperature.
5. Use the flux with a specific gravity of min 0.81.
（EC-19S-8 by TAMURA Corporation, or equivalents.）
Notes
Conditions for Auto-dip
Available for Snap-in Type and Radial Type
（Except SKHJ, SKHL, SKQJ, SKQK, SKEG series）
1. The above temperature shall be measured of the top of switch. 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.
