Most of all B grading and one C are due to badly trimmed pixels. The threshold after trimming usually has 3(!) separated peaks.
We should understand this feature. |
More modules have been re-analysed:

1603: C->B
1602: C->B
1601: B->A
1545: C->C (too many pixels on ROC14 are badly trimmed, to be retested tomorrow) |

M1599: B due to leakage current at +10 (2-3umA)
M1613: B due to a few pixels with bad trimmed threshold
M1624: B due to a few ROCs with mean noise>200electrons

HDIs: 6021, 3014, 2005, 2009, 2006 and 2010 are OK

Looks like lower than 800V measured effect relates to the cable.
After cable has been changed all measurements 790V |

Fri Mar 27 14:32:11 2020, Andrey Starodumov, HDI test, List of suspicious HDIs
|
Here are HDIs that the first time tested showed 500-600V measured on the pin or directly on the HDI pad instead of 800V:
5006, 5007, 2005
3014, 3017, 3019, 6021
I put them in the box called "For Wolfram ...." on the Wolfram's desk in the lab.
Nevertheless, I think this is an artificial issue that mmight be caused by a cable. I retested 5006, 5007 and 2005 with a new
cable and in all cases measured HV=790V what is normal. |

M1542 nothing on sdata3 (12-15), bad output or wire-bond
M1544 ROC15 timing off, can be made to work (roc 15 vdig 11, ..), but probably not usable for the detector
M1545 full readout, ok, upgraded to C*
M1546 TBM1 output alpha broken (sdata1) => replace TBM1
M1563 ROC 8 thinks he is roc 10 ==> check address wire bond on roc 8?
M1567 roc 11 missing, sdata2 (b-channel)
M1572 sticker says : both TBMs broken, no SDA => replace both TBMs?
M1575 no readout from rocs 0,1 (tbm0b, sdata4), all rocs programmable ==> TODO check CTR roc 0
M1593 tbm0, core B (roc 0-3), no decodable output, core/stack working ok, output beta+ high ~ 2V
M1594 roc 0 dead
M1615 nothing on sdata 3 (12-15), very bad cable (corrosion?) re-running with new cable
M1616 ROC 10 not programmable, no roc headers on sdata2 (b) ==> TODO check clock to roc 10
M1617 readout but no hits in ROC 8, mechanical damage on chip edge
M1621 ROC 8 not programmable, no roc headers or tbm trailers on sdata2a (tbm1b) ==> TODO check clock on ROC 8
M1623 probably no cal-trig-reset to roc 0-3
M1625 definitely not cal-trig-reset to roc 0-3 (CTR- at 0V), damaged when trying to pull wire-bonds |

M1542 is fully OK. It's graded C due to very broad relative Gain distribution of ROC6.
If we will have time it would be useful to take a close look at this module.
It remains graded C. |

ROC8-11 are affected (no data)

M1629: B due to mean noise at -20C
M1630: C due to ROC1 with all pixels failed of PH calibration (Gain). Both FT at -20C are A!
Should be understood and retested. Put in C* tray.
M1631: B due to mean noise in all 3 FT
M1632: A |

Mon Mar 30 16:46:59 2020, Andrey Starodumov, DB, Sensors missing in Advacam spreadsheet
|
Dinko noticed that several sensors are missing in Advacam spreadsheet:
- 381785-03-3 used for M1586
- 381783-02-1 used for M1617
- 381783-03-3 used for M1618
- 350853-16-1 used for M1619
It means that information about about ROCs used for these modules is missing in the Module_Assembly spreadsheet. |

For 3 HDIs: 3014, 3017, 6021, HV has been re-measured. In all cases 790V is measured with 800V supplied.
2 HDIs: 1026, 5022 were tested. Both OK.
All 5 HDIs will be used in module assembly. |

M1558: B
M1606: C again due to trimmed threshold for 189 pixels of ROC2 at -20C. Second time at -20C and at +10C the number of failed pixels is 90+, hence grading is B.
We could manually upgrade this module to B.
M1634: A

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. |

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 |
