Splay terminals allow for automatic insertion by IC insertion machine.
•
Insert moulding of terminals and ultrasonic welding improve flux proofness and enable
flux washing in whole by top tape sealing.
•
NDI series (raised actuator) available for different purposes.
•
Double contacts offers high reliability.
•
Vapour phase solderable, IR-reflow solderable.
•
Terminal plating by gold give excellent results when soldering.

Soldering and Cleaning Process:
For best results, please follow these recommendation:
Keep all switch contacts in their "OFF" position for all operations.
Wave soldering
Hand soldering
: Recommended solder temperature at 500°F (260°C) maximum, 5 seconds. For through hole type.
: Use a soldering iron of 30 watts, controlled at 608°F (320°C) approximately 2 seconds while applying solder.

Care should be exercised so that flux from the upper part of the printed circuit board
does not adhere to the switch.
Do not clean the switch body except with top tape sealed type, which can only spray
of cleaning method from top s/w.
