DX48H Series SOLDERING CONDITIONS: Condition for Soldering MAX 260° 255° 230° 150° Room Temperature 120~150sec 5~10sec 60sec TIME(sec) The condition mentioned above is the temperature on the Cu foil of the PCB surface. There are cases where board's temperature greatly differs from switch's surface temperature depending on board's material, size, thickness, etc. Care, therefore, should be used not to allow switch's surface temperature to exceed 260ɗ. Manual Soldering Soldering Temperature Max,350ɗ Continuous Soldering Time Max,5 seconds Precautions in Handling 1. Care should be exercised so that flux from the upper part of the printed circuit board does not adhere to the switch. 2. Don’t clean the switch body except with top tape sealed type, which can only spray of cleaning method from top of s/w. 3. Slide the DX48 actuator from sec operation.
