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 for fix measurement. 3. Temperature profile https://www.alps.com/prod/info/E/HTML/Tact/SurfaceMount/SKTK/SKTKABE010.html 3/4 2018/5/7 SKTK Series - Basic information (1) The above temperature shall be measured of the top of switch. There are cases where PC board's temperature greatly differs from that of the switch, depending on the material, size, thickness of PC board's and others. Care, should be taken to prevent the switch's surface temperature from exceeding 260℃. (2) Soldering conditions differ depending on reflow soldering machines. Prior verification of soldering condition is highly recommended. Manual Soldering Items Condition Soldering temperature 350℃ max. Duration of soldering 3s max. Capacity of soldering iron 60W max. 1. Consult with us for availability of TACT switch™ washing. 2. Prevent flux penetration from the top side of the TACT switch™. 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 returns to normal temperature. https://www.alps.com/prod/info/E/HTML/Tact/SurfaceMount/SKTK/SKTKABE010.html 4/4
