Soldering Specifi cations
⑴ Manual Soldering Device ： Soldering iron 360℃, Max.; 3 seconds, Max.
⑵ Auto Soldering Device: Jet wave type or dip type 275℃, Max.; 6 seconds, Max.
・Pre-heating should be done at temperatures from 80 to 120℃ and within 120 seconds.
⑶ When soldering two or more terminals to the common land, use the solder resist to solder them independently.
Flux Cleaning
⑴ For the solvent, use the fl uorine-based or alcohol-based solvent. Solvent: Fluorine or Alcohol type.
⑵ Do not use the ultrasonic cleaning system.
Mounting of Switch
⑴ Use the PC boards of φ1 holes.
⑵ Do not bend the terminals before mounting the switch on the PC board.
⑶ After mounting the switch, do not place the device in such a way that the device weight will be applied on the knob, etc. of the switch.
⑷ Do not apply a load exceeding 29.4 N (3 kgf) to the knob.
