Wed Mar 11 17:12:05 2020, Matej Roguljic, HDI test, HDI testing procedure change
|
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 Sep 18 15:45:45 2019, Matej Roguljic, Module assembly, HDI sparking under HV test 7x
|
HDI [B]8010[/B] passed all test except the HV. Under the HV test, some sparks could be heard and even seen by eye on the right TBM (closer to the HV pad!).
Testing it again, showed that it was indeed damaged by the spark. Sparking craters could be seen with the microscope between pads 4 and 5 of the TBM.

Wed Aug 7 11:49:07 2019, Matej Roguljic, Module assembly, HDI glue irradiation tests 10x
|
Six different glues were used to glue the cap on six dummy modules. They were all irradiated to 120 MRad in Zagreb after which they were taken to PSI and
tested with the tweezers under the microscope.

|
Silvan has made additional grooves on the gluing stamp which now sits stably on top of the module without any rocking motion and also allows better glue
distribution to all the HDI components that are supposed to receive the glue. |

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.

|
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 |

|
Friday, 24.1., it was noticed that the modules are graded as 'C' in similar fashion. Module is graded A/B at +10 degrees and then graded C at -20. The reason
for grade C was that the trimming procedure was not successful on at least one of the ROCs on each module. This problem was further investigated on 27.1.
Wolfram suspected that the problem lies in zero suppression mode since the pixels with failed threshold comes in groups of four pixels. The corresponding |

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

|
M1662: Grade C due to failure of ROC4 in almost all tests: PixelAlive, PH calibration etc
Should be investigated and retested. At Reception PixelAlive etc was OK, only one double column showed problems
M1675: Grade B due to mean noise > 200e for several ROCs

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!
