Wave Soldering Process*
......Recommended solder temp. at 260°C
(500°F) max., 5 sec.
Hand Soldering Process*
................Use a soldering iron of 30 watts
or less, controlled at 320°C (608°F) for
approx. 2 sec. while applying solder
Cleaning Process*
..............Flux clean using force rinse, high
agitation or triple bath cleaning method.
Freon TF or TE give excellent results.
When vapor methods are used, do not
subject the switch to solvents at
temperatures above 51°C (125°F).
Standard Packaging
......IC tubes/all poles in the “off” position
