WAIVERS

• One waiver was submitted to fly a commercial, unqualified thermistor, which is used only during ground test and integration.

• The waiver was withdrawn when a suitable part mounting was not available


FORMAL INSPECTIONS

• ALL HYBRID MICROCIRCUITS (100%) USED IN FLIGHT HARDWARE WERE PRE-SEAL VISUALLY EXAMINED AT THE

MANUFACTURER'S FACILITY.

• ALL ASSEMBLY AND TEST OPERATIONS ON THE DETECTORS (100%) WERE WITTNESSED BY MIT


QUALIFICATION

• TWO (2) EEE PART TYPES WERE SUBJECTED TO QUALIFICATION TESTS, IN ACCORDANCE

• WITH EEE-INST-002

• INTERFET P/N SNJ90347(IF9030) PASSED EEE-INST-002 QUALIFICATION TESTS ON 4/5/07

• KEMET 1000V, 0.022UF CERAMIC CHIP CAPACITOR FAILED QUALIFICATION LIFE TEST. THE PART WAS DESIGNED OUT

OF THE SYSTEM IN FAVOR OF A QUALIFIED CALRAMIC CAPACITOR
