After exchange of TBM1 the results is the same:

WAS:
1567: Grade C, no data from ROCs 8-11, looks like a problem with one TBM1 core

NOW:

Entry  Mon Apr 6 14:52:09 2020, Andrey Starodumov, Reception test, RT of M1657 failed 
No hits in ROC14 and ROC15.
Here is an error:
"ERROR: <datapipe.cc/CheckEventValidity:L524> Channel 5 Number of ROCs (1) != Token Chain Length (2)"
To module doctor!
Entry  Mon Apr 6 14:42:43 2020, Andrey Starodumov, Reception test, RT of M1575 failed 
Silvan has substituted the TBM0 of M1575.
Still no hits in ROC0-ROC3: "NO DATA" "IDLE DATA" warnings
The long cable has been attached.
To module doctor!
Entry  Mon Apr 6 14:27:31 2020, Andrey Starodumov, Reception test, M1593 
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.
Reception test grade: A

Correction:
in reality M1546 has been tested and NOT 1646. M1646 failed Reception due to not working ROC and graded C.
I hope we we will find a way to correct properly the module name and rerun MoreWeb analysis.

Folder with test results has been renamed from M1646 to M1546:
mv M1646_FullQualification_2020-04-02_08h41m_1585809682 M1546_FullQualification_2020-04-02_08h41m_1585809682

Dinko fixed logfiles and .tar file.

Results of M1646 has been removed with python Controller.py -d (remove all rows related to M1646).
Entry  Fri Apr 3 18:06:11 2020, Andrey Starodumov, HDI test, 2 HDIs tested 
HDIs 6018 and 6019 are passed tests.
Entry  Fri Apr 3 17:39:19 2020, Andrey Starodumov, Module doctor, M1654 
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.
It would be useful if Wolfram take a look and decide what to do. Silvan proposed to remove cap and repair wire-bonds.
I could test the procedure on a dummy module (I have one) with glued cap and, if successful, do the same with M1654.
For the moment the module is placed in Module doctor tray.
Entry  Fri Apr 3 17:29:51 2020, Andrey Starodumov, Full test, FT of M1557, M1591, M1649, M1651 
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
M1651: B due to mean noise > 200electrons for several ROCs

For both modules C grading is an artifact. Should decide how to proceed with such cases.

M1557 and M1649 will be placed for the moment in C* tray.

Retested M1545: C->B (to be correct on the MoreWeb summary page)
Retested 1557: C->C in one ROC >160 pixels failed to be trimmed Module placed in a tray C*
1627: B
1628: B

All B grades due to high (>200electons) mean noise.

Final grade in the MoreWeb summary page is corrected.
Module graded B.
Entry  Fri Apr 3 14:18:15 2020, Andrey Starodumov, Reception test, RT of M1651 on April 2 
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:
:~/L1_DATA/M1651_Reception_2020-04-02_16h09m_1585836596 (but the .tar file is still there), run python Controller.py -d (and remove raw with C grade from GlobalFinalResult) and rerun python Controller.py -m M1651

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
M1638: A
M1639: B Due to B at first -20C test. ROC8 mean noise >200electrons. Second -20C and at +10C both are graded A
M1640: B All three FT are B due to several ROCs mean noise >200electrons

Following procedure of regrading the first -20C test has been manually upgraded to B. The final grade is A since manual upgrade was not taken in to account. I do not know why. So, the module will be graded A.
Entry  Fri Apr 3 13:55:48 2020, Andrey Starodumov, Reception test, M1653 failed Reception 
Roc12-15 are not programmable.
Visual inspection is Ok, nothing found.
To module doctor!
Entry  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.
I think we do not need to repeat FT for this module.
I put it in a tray with good modules.

Entry  Thu Apr 2 17:06:19 2020, Andrey Starodumov, Reception test, M1652 failed Reception 
ROC1 of M1652 is not programmable.
Put in the "Bad" tray as C module.

M1641: B due to mean noise > 200electons for a few ROCs
M1642: B due to mean noise > 200electons for a few ROCs
M1643: B due to mean noise > 200electons for a few ROCs
M1644: B due to mean noise > 200electons for one ROCs at -20C
Entry  Tue Mar 31 17:33:37 2020, Andrey Starodumov, Reception test, RT of M1546 
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
to see whether we could substitute TBMs on another 6 modules with broken TBMs.

Cap has been glued to M1546. No damaged wire-bonds. Vthr-CalDel and PixelAlive are OK.
Module to be (FT) tested tomorrow.

M1646 showed Idig=1A, ROC6 is not programmable.
Visual inspection: scratch on a periphery (between bonding pads) of ROC6.
