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 (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. http://www.alps.com/prod/info/E/HTML/Tact/SurfaceMount/SKRA/SKRAALE010.html 4/5 2017/6/19 SKRA Series - Basic information 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. 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. Please place purchase orders for taping products per minimum order unit (1 reel or a case). 3. For φ330mm diameter reel requirements, please contact us. 4. This products can be used in vehicles. Although these products are designed to perform over a wide operating temperature range, please ensure that you receive and read the formal delivery specifications before use. 5. Protective structure : Assumes the switch is left alone without being operated. Under the specified conditions, dust and water ingress with a significant impact on the switch's on-off function is prevented. IP67 dust and water resistance is guaranteed for the switch alone and performance may not be guaranteed depending on the mounting conditions and usage. http://www.alps.com/prod/info/E/HTML/Tact/SurfaceMount/SKRA/SKRAALE010.html 5/5
