ROC8 of M1617 is programmable but no readout from it.
Silvan noticed that a corner of one ROC of this module is broken,
this is exactly ROC8. |

ROC10 of M1616 is not programmable, no readout from ROC10 and ROC11.
Visual inspection of wire bonds - OK
To module doctor! |

M1615: one pixel in ROC10 unmaskable hence should be graded C. Otherwise the module is of grade A
To be checked! |

|
FT of this modules has been done twice: March 23 and March 25, in both cases with the final test SW. On March 23 module was graded C due to many trim bit
failures. That is why it was retested. But after failure in trimbits were excluded from the grading, FT of Mar 23 looks better then later FT of Mar25.
That is why FT of Mar 23 is kept. |

Reception test done and caps are glued to modules M1609-M1612.
M1611 graded B due to double column failure on ROC13. Others graded A. |

|
I have looked more closely at M1606.
Trimming show problems in ROC2, 8 pixels have 0 threshold and for 61 pixels thr=-1.
Strange because from Scurves the 61 have a high ~62 threshold but no failure.

On Friday I have tested M1606 at room temperature in the red cold box.
Previously it was reported that trimming does not work for ROC2.

Andrey and I assembled modules 1601 and 1602 on Friday, 13.3. On Monday, 16.3. I ran reception on them (both graded A) and then glued protection caps on
them. |

|
| ROC5 has eff=93.65% and should be graded C. Somehow efficiency was not taken into account for HR test grading??? |
|
Wed Sep 2 16:09:24 2020, Matej Roguljic, Modules for P, M1595 switch with M1558
|
Module 1595 was foreseen to go on the inner ladder 5, position -2 (negative two). During the pre-installation test, we saw it had a high leakage current,
~8 microAmps at room temperature. Therefore, we decided to place module 1558 in its place instead of it. |

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.

Wed Mar 11 15:34:57 2020, Urs Langenegger, Other, M1586: issues with MOLEX?
|
Module M1586 had passed the full qualification on 20/02/27. I had had to re-insert the cable in the Molex connector for it to become programmable.
On 2020/03/09, I tried to re-test M1586, but it was not programmable. Visual inspection revealed nothing to me. I did re-insert the cable once again, but |

M1582 was classified as C because of 167 pixels failing trimming in ROC1.
I have tested this module.
The attached plots show the 1d & 2d threshold distributions.
