Soldering Conditions
■
Condition for Reflow
Available for Surface Mount Type.
1. Temperature measurement: Thermocouple φ 0.1 to 0.2 CA（K）or CC（T）at solder joints
（copper foil surface）
.
A heat resistive tape should be used to fix thermocouple.

Notes
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.

4.
Prevent flux penetration from the top side of the TACT Switch
TM
.
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.
