Soldering Specifications

  • Manual Soldering
    Device : Soldering iron
    380℃, Max.; 3 seconds, Max.
  • Auto Soldering
    Device : Jet wave type or dip type
    275℃, Max.; 3 seconds, Max.
  • Pre-heating should be done at temperatures below 100℃ and within 30 sec.
  • When soldering two or more terminals to the common land, use the solder resist to solder them independently.

Flux Cleaning

  • Solvent : Fluorine or Alcohol type.
  • The BT series are not washable. To wash the PC board,clean the soldering surface of PC board with a brush so that the switch is not exposed to the cleaning solution.
  • Cleaning after soldering should be done after the terminal temperature falls to 90℃ or below, or after leaving the switch for five minutes or longer at room temperature.

Mounting of Switch

  • Use PC boards with hole diameter of 0.8mm.
  • Do not bend the terminal pins before mounting the switch on the PC board.
  • After mounting the switch, do not place the device in such a way that the device weight will be applied on to the actuator of the switch.
  • Do not apply load exceeding 29.4N to the actuator.
