ABSTRACT:
Problems resulting from contamination of electronic apparatus used with silicone keypads can be eliminated or substantially reduced by soaking such keypads prior to assembly in a low molecular weight liquid hydrocarbon, particularly n-hexane. Such soaking removes low molecular weight unreactive cyclics from the keypad which might otherwise contaminate the electronic apparatus.
