Cleaning
⑴Solvent
: Fluorine or Alcohol type.
⑵The
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.
⑶Cleaning
after soldering should be done after the terminal
temperature falls to 90℃ or below, or after leaving the switch
