Urs Langenegger | Full test | exchanged adapter for DTB_WXC03A |

So I exchanged the module adapter with the one from the blue box, and all issues with r/o were gone (with both modules)
Of course, the apparently flaky adapter from WXC03A seems to be working again/now in the blue box.
Just fyi. |
Today I have to reconnect a few times modules to the module adapter in the blue box.
It looks like the Molex connector is a bit damaged. One should be very careful while connecting a cable to this Molex connector. |

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. |

Urs Langenegger | Full test | M1637 |
Maybe M1637 has an issue: It got stuck twice at the same place with
[09:53:16.043] <TB0> INFO: PixTestReadback::CalibrateIa()
[09:53:16.043] <TB0> INFO: ----------------------------------------------------------------------
[09:53:17.924] <TB0> ERROR: <datapipe.cc/CheckEventID:L486> Channel 6 Event ID mismatch: local ID (22) != TBM ID (23)

After that, the DTB is unresponsive and elCommandante loses it. (The printout above is from the second testrun. I had restarted the complete fullqualification after realizing that DTB0 was 'missing' and checking manually that M1637 was properly connected).
I hope elCommandante manages this gracefully. |

I did not manage to get any r/o from the module connected to that adapter, also after exchanging the module.
So I exchanged the module adapter with the one from the blue box, and all issues with r/o were gone (with both modules)
Of course, the apparently flaky adapter from WXC03A seems to be working again/now in the blue box.

Andrey Starodumov | Full test | FT of 1558, 1606, 1634, 1636 on Mar 30 |
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
M1636: A |

danek kotlinski | Module grading | M1542 |
I have tested M1542.
It looks not bad but there is a group of pixels in the lower/left corner of ROC6 which behave different.
One can also see that something is not right in some PH optimisation plots.
See the attached plot.
We should probably leave this module as grade C+.
D. |

2 HDIs: 1026, 5022 were tested. Both OK.
All 5 HDIs will be used in module assembly. |

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. |

Urs | Full test | FT of M1629, M1630, M1631, M1632 |
M1630 is interesting because (I am using my terminology in the following) for the test at T=+10C ROC1 fails the PH optimization test and by consequence the gain/pedestal test is also failed.
The PH optimization test is failed because the minimum pixel on which the test is based is a 'dead' pixel (according to the PixelAlive test), but unfortunately has hits in the initial PH map. As a result the phscale and phoffset for this ROC are not optimal and this is seen in the gain/pedestal fits.
Please find the plots attached from the T=+10 tests. |

Danek Kotlinski | Full test | FT of M1629, M1630, M1631, M1632 |
I have tested M1630.
I see not problem with ROC1. See the attached plot.
There is one dcol in ROC12 which shoes the "pattern" problem seen in a few other ROCs.
I think this module is fine, should be B. Could be retested. |

Andrey Starodumov | Full test | FT of M1629, M1630, M1631, M1632 |
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 |

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. |

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. |
