 Wed Apr 1 14:36:37 2020, Andrey Starodumov, Reception test, M1646 failed Reception
|
M1646 showed Idig=1A, ROC6 is not programmable.
Visual inspection: scratch on a periphery (between bonding pads) of ROC6.
To module doctor! |

[quote="Andrey Starodumov"]This is a module with a broken TBM. Silvan put a new one on top of the broken TBM.
The module is graded A after reception test.
I'm still not sure that wire-bonds of the new TBM is lower than capacitors. I'll try to glue a cap tomorrow

M1641: B due to mean noise > 200electons for a few ROCs
M1642: B due to mean noise > 200electons for a few ROCs

ROC1 of M1652 is not programmable.
Put in the "Bad" tray as C module. |

Thu Apr 2 17:10:08 2020, Andrey Starodumov, Other, Cap glued to M1618
|
M1618 has been tested (FT ) on March 23 without a protection cap.
I have no idea how it's happened...
Today cap is glued and module passed Reception test again and it's A.

[quote="Andrey Starodumov"]M1637: C. Graded C due to not completed first test at -20C. Urs has reported issues. The second -20C after T-Cycle and test at
+10C are graded A.
Tomorrow I'll upgrade this module manually to A

Due to damaged module adapter the first Reception test failed and after MoreWeb analysis graded C.
After second Reception test (with proper connected cable) the grade is A.
To keep grade A instead of C in the MoreWeb summary table I removed the directory of the first Reception:

Correction:
in reality M1546 has been tested and NOT 1646. M1646 failed Reception due to not working ROC and graded C.

M1557: C due to 214 pixel threshold failure in ROC4 only at +10C (several previous FTs at +10C were graded B!)
M1591: B due to mean noise > 200electrons for several ROCs
M1649: C due to 270 pixel threshold failure in ROC11 only at +10C

After a protection cap glued to M1654, I observed a few strongly bent wire bonds and probably some shorts on ROC8. One (VD+) of them is even detached (on
HDI side). Pads from 25/26 till 35 are affected.
Nevertheless the Reception test gave the same results as before the cap gluing: grade A.

Silvan has substituted the TBM0 of M1593.
I had to substitute a cable that has residuals and with which the Reception test failed completely.
The long cable has been attached.
