Soldering Condition
Example of Reflow Soldering Condition
1. Heating method:
Double heating method with infrared heater.
2. Temperature measurement:
Thermocouple 0.1 to 0.2 Φ CA (K) or CC (T) at solder joints (copper foil surface). A heat resisting tape
should be used to fix thermocouple.

(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 are common to this series/models.
1. This site catalog shows only outline specifications. When using the products, please obtain formal
specifications for supply.
2. 4-directional operating force and travel are measured at 4.3mm height from the bottom of the switch.
3. Please place purchase orders for taping products per minimum order unit (1 reel or a case).
