Abstract:
In selecting squibs stored from the Viking Orbiter 1975 program for use in the Voyager 1977 mission, it was found that moisture sealed within the squibs at the time of manufacture had combined with the boron ignition mix to produce boric acid and corrosion. The manufacture of hermetically sealed squibs must preclude the presence of moisture prior to hermetic sealing. Flight quality squibs in bonded storage must receive periodic resistance checks to detect degradation.
