Heating method: Double heating method with infrared heater. 2. Temperature measurement: Thermocouple 0.1 to 0.2 Detector Push Slide Rotary Encoders Power CA K or CC T at solder joints copper foil surface . A heat resistive tape should be used to fix thermocouple. 3. Temperature profile Temperature (C ) 260C max. 3 sec max. 180 150 Time 230C Dual-in-line Package Type TACT SwitchTM 40s max. 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. Sharp Feeling Soft Feeling Snap-in Type Surface Mount Type Radial Type Conditions for Auto-dip Available for Snap-in Type and Radial Type Except SKHJ, SKHL, SKQJ, SKQK, SKEG series Items Flux built-up Condition Mounting surface should not be exposed to fluk Ambient temperature of the soldered surface of PC board. 100 max. 60s max. 260 max. Manual Soldering Except SKRT Series Items Soldering temperature Duration of soldering Capacity of soldering iron Condition 350 max. 3s max. 60W max. Preheating temperature Preheating time Soldering temperature Duration of immersion Number of soldering 5s max. 2times max. Notes 1. 2. 3. 4. 5. Consult with us for availability of TACT SwitchTM washing. 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. 306 |
