Production of UFE (FM) Integration + 358VA Chips Tests Select 202 Chips 101Production of 4 Types PCB Series of Space Qualification Tests Functional Tests TVT 3D Vibration Coating TVT
Space Qualification Tests Random Vibration X,Y and Z-Direction aRMS = 6.8g, 20-2000 Hz for 120 sec Functional test without failure 1st TVT Temperature : -40oC … +80oC Pressure : 110-5 mbar Functional test without failure 2nd TVT Same as 1st TVT condition Conformal Coating
Thermal Profile in TVT Operating Temperature (-20 ~ +50 oC) : Gain Calibration Points
Noise after SQT Noise = 1.5 ADC == ENC = 4000 e- Common mode noise corrected Pedestal RMS
Gain Calibration +50 oC -20 oC
Gain vs. Temperature All 6464 channels are calibrated over full Temperature range
Flight UFE Selection ALL 101 produced UFEs within specificationsSelect “better“ UFEs as flight modules
TRD-UFE (FM) Pedestal Distribution : ~ 10% of full range
TRD-UFE (FM) Noise RMS Spread : ~ 4%
TRD-UFE (FM) Gain RMS Spread : ~ 3% 25oC
TRD UFE Summary UFE(FM) Production : Finished (Jul. 2005) Total = 101 UFEs (FM = 82, FS = 19) Functional Tests : Finished (20.07.05) UFE Space Qualification Tests (Mar.05 ~ Mar. 06) 1st Thermal Vacuum Test = 101 (Done w/o failure) Random Vibration Test = 101 (Done w/o failure) Conformal Coating = 101 (Done w/o failure) 2nd Thermal Vacuum Test = 101 (Done w/o failure) Best 82 FMselected (Mar. 2006) UFE Integration : Finished (Apr. 2006)
TRD Gas Manifolds • Distribute TRD gasflow into 41 segments • Measure gastightness of individual segments • Allow isolation of a segment when leaky • Introduce no additional risk of gas leakage
