| SOLDERING AND CLEANING PROCESSES |
| For best results, please follow these recommendations: Keep all switch contacts in their "OFF" position for all operations. |
| WAVE SOLDERING: Recommended solder temperature at 500 F (260 C) max. 5 seconds. |
| HAND SOLDERING:
|
Use a soldering iron of 30 watts, controlled at 608 F(320° C) approximately 2 seconds 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 125
F (51° C). |
