  1. Hybrid & Module Testing Status Week of 6/6-6/10

  2. UCSB Hybrid Testing Status

  3. This Week: 1 shorts in PA Repairable 4 modules repaired Cumulative: 1 with Shorts in PA Repairable 1 Major Scratch in PA Repairable 2 noisy on edge channels Should be ok 1 Smashed APV-PA Bonds Repairable 6 Failed Inspection Never should have sent 1 Broken Ceramic 1 Bad Bond Feet 1 Weak Wirebonds 1 Too Many Opens 4 with unknown failure Effects entire chip(s) UCSB Hybrid Testing Failures

  4. FNAL Hybrid Testing Status

  5. This Week: Cumulative: 7 with Shorts in PA Repairable 1 Major Scratch in PA Repairable 1 Damaged during repair 5 Too Many Opens + Noisy 14 with unknown failure Effects entire chip(s) FNAL Hybrid Testing Failures

  6. US Hybrid Testing Status

  7. UCSB ARCS Testing Status

  8. This Week None Cumulative 2 with too much current 1 with >2% bad channels 1 with bad DCU Repairable 1 with CF frame shorted to HV Repairable 1 with bad Dec. Mode chip UCSB ARCS Testing Failures

  9. UCSB ARCS Testing Results • 945 Total Tested • 936 Grade A • 3 Grade B • 6 Grade F • This week: • 10 of 44032 channels bad (0.023%) • Total Production: • 304.5 of 643328 channels bad (0.047%)

  10. FNAL ARCS Testing Status

  11. This Week (8387-8446, 60 modules). 1 mod, real pinholes (8417, chs 1,4,6,7 PASi pulled), OK. 1 mod 30 mkA at 15V (8421, ch 289 PASi pulled), OK. no PHL- 3 SHT (8411, 8430, 8434). Cumulative (7835-8446) 2 grade “B” (mishandling; missing bonds on p/a) 7970 - breakdown current behavior @430V Total of 14 pinholes Grade F – problem with chip #2 (every 8th channel is identified as PHL-) Grade F-High current 8289 Cumulative (7702-8446, 745 modules, ARCSed 744) 2 grade “B” (mishandling; missing bonds on p/a) 2 grade “F” mishandling 1 grade “F” under study 7970 - breakdown current behavior @430V FNAL ARCS Testing Failures

  12. FNAL ARCS Testing Results • 747 Total Tested • 737 Grade A • 2 Grade B • 5 Grade F • This week: • Total Production:

  14. UCSB LT Testing Status Failed module has too much current

  15. FNAL LT Testing Status • Modules 30200020008325 – 8345, 8425-8434, 8413-8422 • were tested during June 9 – June 13. • We did 4 runs. • K-Mux errors were happening two times – only in the beginning of new run, program had to be restarted • Quick connect between hose and coldbox was damaged and leaking. Replaced quick connect and renewed the liquid – delay in one run. • Module 8348 had high leakage current (~2.8uA@450V) and steeper then usual. • Modules 8331, 8336-8345, 8431 had high noise in the cold record (~3.5ADC) -> all channels marked NOISY -> xml :-1: • Possible reason – no HV bias during cold cycle. Need more quiet time to investigate. • Backlog: 54 modules
