4 Soldering Conditions Condition for Reflow Available for Mount.. Heating method: Double heating method with infrared heater. 2. Temperature measurement: Thermocouple 0. to 0.2 CAKor CCTat solder jointscopper foil surface. A heat resistive tape should be used to fix thermocouple.. Temperature profile Temperature ( C ) C max. sec max. 20 C 40s max. Time Package to 4min. Time inside soldering equipment s. 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. Conditions for Auto-dip Available for and Except SKHJ, SKHL, SKQJ, SKQK, SKEG series Items Flux built-up Preheating temperature Condition Mounting surface should not be exposed to fluk Ambient temperature of the soldered surface of PC board. 00 max.
