SOLDERING
TEMPERATURE:
Wave soldering temperature at 260+/-5 Celsius
degree for max. 5+/-1 sec. For hand soldering,
temperature is at 350+/-5 Celsius degree with a
60W iron head within 3sec. Please note do not
apply soldering iron directly on the terminals
when soldering.
RELIABILITY
COLD TEST: Switch for testing being kept in the conditions
at -40±2 Celsius degree in temperature for 96
hrs. Afterwards, the switch shall be left in a
normal ambient condition for 1 hr then to be
measured within 1 hr. Drop of water must be
taken away. There shall be no defect in
appearance or in the mechanical functions.
Contact resistance 20m-ohms max.
