During the first fulltest@-20 of the full qualification procedure for modules: 1539, 1541, 1542 and 1543; an error message popped up "psi Agente: self.Testboards[0]
failed - the following boards are busy: TB1(DTB...:M1541), TB2(DTB...:M1542), TB3(DTB...:M1543). This means that the first fulltest for module 1539 was
not executed.

|
There is an additional test that will be used from 11.03. on all HDIs. It involves measuring the voltage between ground and the HV pin of the needle card
with the goal of checking whether proper voltage is delivered to the HDI. The HDI testing script has been updated and it now prompts the user to set the
voltage to -800 V, measure the voltage on the pin and write this into the test results. After this, another instruction has been added which tells the |

Wed Mar 11 17:22:57 2020, Matej Roguljic, HDI test, 8 HDI tests on 11.3.
|
I tested 8 HDIs today: 5029,5030,5031,6034,6036,6035,1031 and 1032
All of them tested fine. |

Thu Mar 12 12:19:43 2020, Matej Roguljic, HDI test, 5 HDI tests on 12.3.
|
I tested 5 HDIs on 12.3. 1030,1029,1040,1039 and 1038. 1039 failed all the electrical tests. All the others passed the tests. HDI 1038 has one wirebond
which is connected to the pad on the HDI and then it extends back up (like this: TBM./\.HDI/). The connection is good, but I just want to check with Silvan
later if this is a problem. |

Mon Mar 16 10:05:23 2020, Matej Roguljic, Software, PhQualification change
|
Urs made a change in pXar, in the PhOptimization algorithm. One of the changes is in the testParameters.dat where vcalhigh is set to 100 instead of 255.
This was implemented on the PC used to run full qualification. A separate procedure for elComandante was created, "PhQualification.ini", which runs pretest,
pixelalive, trimming, ph and gainpedestal. This procedure will need to be run on all the modules qualified before this change was made and later merged |

|
Some of the DAC parameters plots were empty in the total production overview page. All the empty plots had the number "35" in them (e.g. DAC distribution
m20_1 vana 35). The problem was tracked down to the trimming configuration. Moreweb was expecting us to trim to Vcal 35, while we decided to trim to Vcal
50. I "grepped" where this was hardcoded and changed 35->50.

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. |

[quote="Andrey Starodumov"]It was discovered that these modules were stored in Zagreb in the climatic lab where T was about +22C. These modules have been
transported from Co60 irradiation facility to the lab on open air with T>30C and RH>70%. Water in the air under the cap condensated on the surface of HDIs
and diluted residuals (from soldering, passivation etc), that after remains liquid or crystallised.

Today I performed my first cap gluing. As an exercise it was first done on two dummy modules and later on a pre-production module M1522. Before the cap
gluing the module M1522 was visually inspected and a Reception test was run. Before the cap gluing everything looked fine. After the cap gluing the module
M15222 was again visually inspected and it looked like wire bonds in one of the corners might have been slightly bent and some glue got deposited on some |

[*] Today Silvan wire bonded TBMs to the first batch of 8 new HDIs which were then tested. 5 out of 8 HDIs received a passing grade. Of the 3 failing HDIs,
2 had a spark occurring. The final testing results can be found in [URL=https://github.com/mroguljic/HDI_L1/blob/bb78cddaacc7488910aa26bbf609fcff3618c597/HDIresults.csv]https://github.com/mroguljic/HDI_L1/blob/bb78cddaacc7488910aa26bbf609fcff3618c597/HDIresults.csv[/URL]. |

First production modules (M1530, M1531, M1532) were built on Monday, Sep. 30 2019.
There was a problem with wire bonding of ROC5 on M1530. There is a small crater on one of the ROC pads which appears to had been created by the BareModule |
