two of are fixed and can be re-tested
M1623 tbm bond
M1657 bond roc 15
the others need further investigation, maybe a new tbm, maybe closer wire-bond inspection
M1633 roc 0-3 programmable, but no readout, unclear
M1635 roc 12-15 programmable, but no readout (except for roc 12), no token passed
M1653 roc 12-15 not programmable, otherwise ok, sda? tbm?
M1671 some problem with roc 14/15, unclear |

Tue Apr 14 17:29:46 2020, Andrey Starodumov, General, ROC4 or ROC12 defects
|
Starting from M1650 almost every module has a cluster of dead pixels or broken bump bonds on
ROC4 or (more often) ROC12. The number of defects varied from 20 to 40.
It's almost excluded that such damage is made at PSI, since both of us: Silvan and me, first time connected the cable
to the module.
It would be interesting to check whether these bare modules arrived all together. |

|
M1668: Grade B due to mean noise >200e for several ROCs
M1669: Grade B due to ROC2 mean noise >200e
M1670: Grade B due to ROC1 mean noise >200e
M1672: Grade B due to mean noise >200e for several ROCs |

Tue Apr 14 16:54:31 2020, Andrey Starodumov, Other, M1633 cable disconnected
|
We do not have any more module holders.
M1633 was in "Module doctor" tray.
I took module off the holder and put it in a gel-pak. |

Tue Apr 14 15:49:05 2020, Andrey Starodumov, Reception test, RT of M1623, M1657, M1673, M1674
|
M1623: Grade A, should be B due to 71 bump defects in ROC4
M1657: Grade B, due to 51 dead pixels in ROC12
M1673: Grade A, again 31 dead bumps in ROC12
M1674: Grade A, again 39 dead bumps in ROC12 |

Thu Apr 9 17:43:54 2020, Andrey Starodumov, HDI test, 4 HDIa tested
|
| HDIs 3029, 3031, 3032, 4042 passed tests. All OK. |
|
Thu Apr 9 17:36:31 2020, Andrey Starodumov, Reception test, RT of M1671 failed
|
ROC12-ROC15 no hits.
A candidate to TBM0 substitution, hence Grade C*.
To Module doctor1 |

Thu Apr 9 17:24:49 2020, Andrey Starodumov, Full test, FT of M1654, M1665, M1666, M1667
|
M1654: Grade A
M1665: Grade B due to noisy pixels in ROC5. To be checked by module doctor!
M1666: Grade B due to mean noise of several chips > 200 electrons. Again on ROC12 there is a cluster of 31 dead bumps!
M1667: Grade B due to mean noise of several chips > 200 electrons. Again on ROC12 there is a cluster of 41 dead bumps!
M1665 goes to Module doctor! |

A few corrections to the list of bad modules:
- On April 7 M1593 has been (F)-tested with a grade B due to Rel.gain width and mean noise of a few ROCs.
- 1611 should be C* since ROC13 has not working double column (160pixels) + 27 trimbit failures but very good trimmed threshold distribution, so these 27 trimbit failures should be ignored. |

Thu Apr 9 14:49:07 2020, Andrey Starodumov, Reception test, RT of M1650 failed

Module has been tested on April 2nd.
Under Molex connector in ROC12 471 dead or noisy pixels.
Grade C. |

| Both modules graded A. |
|
Tue Apr 7 15:25:21 2020, Andrey Starodumov, Reception test, RT of M1662 failed
|
Address decoding of M1662 failed in one double column of ROC4.
To be decided what to do with this module.
Currently in C* tray. |

With CtrlReg=17 the grade of module is B. Still in one double column "noisy" pixels: with hits from other 3 pixels of a cluster.
Stay in C* tray. To come back later. |

M1572: Grade B due to mean noise of ROC4 211 electrons
M1661: Grade B due to mean noise of a few ROCs > 200 electrons and in ROC12 44 pixels failed threshold cut
M1663: Grade B due to mean noise of a few ROCs > 200 electrons
M1664: Grade B due to mean noise of a few ROCs > 200 electrons and in ROC12 44 pixels failed threshold cut |

Wed Apr 8 15:20:38 2020, Andrey Starodumov, Reception test, RT of M1665
|
With CtrlReg=9 RT grade was B due to 90 noisy pixels in ROC5.
Noisy in this case means that one pixel in a 2x2 cluster in a few column got 40 hits instead of 10.
With CtrlReg=17 this problem gone. RT grade is A. |
|
Wed Apr 8 15:02:37 2020, Andrey Starodumov, Software, Change of CrtlReg for RT
|
So far in a blue box for RT tbm10d_procv3 parameters were used.
This is wrong, since CtrlReg=9 is better for -20C while for +10 or higher T
CtrlReg=17 is better.
From now on for RT tbm10d_procv4 will be used. |

M1623: all ROCs are programmable but no readout from ROC8-ROC11.
Visual inspection is OK.
To module doctor. |

Silvan substituted TBM on this module.
Now ROC0 does not have hits.
Grade C, goes to "Bad" tray. |
|
Tue Apr 7 18:02:07 2020, Andrey Starodumov, Reception test, RT of 1654
|
After Silvan removed a cap and re-bonded broken and bent wires M1654 again has been tested.
RT grade is A.
Protection cap to be glued and to be (F)tested. |

Tue Apr 7 17:59:27 2020, Andrey Starodumov, HDI test, 6 HDIs tested

HDIs
2030, 2031, 1021, 1022, 1023, 1035
are tested. All OK. |

Tue Apr 7 16:57:01 2020, Andrey Starodumov, Full test, FT of M1593, M1658, M1659, M1660
|
M1593: B due to Rel.gain width and mean noise of a few ROCs
M1658: B due to threshold and mean noise of ROC15
M1659: B due to threshold and mean noise of a few ROCs
M1660: C due to 172 pixels failed Threshold (trimmed) on ROC7 only at second -20C, the first -20C and +10C trimming threshold is OK for this chip
M1660 to C* tray and retest with all other modules after production, |
