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 Detector Push should be used to fix thermocouple. 3. Temperature profile Temperature (˚C ) Slide 260˚C max. 3 sec max. Rotary 230˚C 180 Encoders 150 Power Time Dual-in-line Package Type 120 sec max.（ pre-heating ） 40s max. TACT SwitchTM 3 to 4min. CustomProducts Time inside soldering equipment 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.

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. （EC-19S-8 by TAMURA Corporation, or equivalents.） 3s max. 60W max.
