The automotive operating temperature range to be individually discussed upon request. 2. ● Indicates applicability to all products in the series, while ○ indicates applicability to some products in the series. 187 TACT SwitchTM Soldering Conditions TM 検 Switch 出 TACT Condition for Reflow Available for Surface Mount Type. 1. Temperature measurement: Thermocouple φ 0.1 to 0.2 CA（K）or CC（T）at solder joints （copper foil surface） . A heat resistive tape should be used to fix thermocouple. 2. Temperature profile Temperature (˚C ) 260˚C max. 3 sec max. Sharp Feeling 230˚C 180 150 Time Soft Feeling 120 sec max. （pre-heating） 40s max. 3 to 4min. Time inside soldering equipment Manual Soldering Condition Flux built-up Mounting surface should not be exposed to flux Preheating temperature Ambient temperature of the soldered surface of PC board. 100℃ max. Items Condition Soldering temperature 350℃ max. Duration of soldering 3s max. Capacity of soldering iron 60W max. Preheating time 60s max. Soldering temperature 260℃ max. Duration of immersion 5s max. Items Condition 2times max. Soldering temperature 360℃ max. Number of soldering SKHH, SKPD Series Radial Type Items Surface Mount Type Conditions for Auto-dip Available for Snap-in Type and Radial Type. Snap-in Type Notes 1. The above temperature shall be measured of the top of switch. 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. SKHH, SKHW, SKRG, SKPD Series Duration of soldering 3s max. Capacity of soldering iron 60W max. Items Condition Flux built-up Mounting surface should not be exposed to flux Preheating temperature Ambient temperature of the soldered surface of PC board. 110℃ max. Items Condition Preheating time 60s max. Soldering temperature 350℃ max. Soldering temperature 260℃ max. Duration of soldering 3s max. Duration of immersion 5s max. Capacity of soldering iron 20W max. Number of soldering 2times max. SKTD, SKTG, SKQJ, SKQK, SKEG Series SKQJ, SKQK, SKEG Series Items Condition Flux built-up Mounting surface should not be exposed to flux Preheating temperature Ambient temperature of the soldered surface of PC board. 100℃ max. Preheating time 45s max. Soldering temperature 255℃ max. Duration of immersion 5s max. Number of soldering 2times max. Notes 1. Prevent flux penetration from the top side of the TACT SwitchTM. 2. Switch terminals and a PC board should not be coated with flux prior to soldering. 3. The second soldering should be done after the switch is stable with normal temperature. 4. Use the flux with a specific gravity of min 0.81. （EC-19S-8 by TAMURA Corporation, or equivalents.） 259
