  69   Thu Feb 6 17:19:12 2020 Dinko FerencekReception testRT for 6 modules: 1551, 1552, 1553, 1554, 1555, 1556
Today reception test was run for 6 modules and looks OK for all module. The modules were graded as follows:

1551: A
1552: A
1553: B (Electrical grade B)
1554: A
1555: B (IV grade B)
1556: B (IV grade B)

Protective caps were glued to these modules.

  116   Thu Mar 19 17:17:27 2020 Andrey StarodumovReception testM1609-M16012
Reception test done and caps are glued to modules M1609-M1612.
M1611 graded B due to double column failure on ROC13. Others graded A.
  118   Fri Mar 20 14:46:31 2020 Andrey StarodumovReception testM1615 failed
M1615 is programmable but "no working phases found"
Visual inspection of wire bonds - OK.
To module doctor!
  119   Fri Mar 20 14:53:52 2020 Andrey StarodumovReception testM1616 failed
ROC10 of M1616 is not programmable, no readout from ROC10 and ROC11.
Visual inspection of wire bonds - OK
To module doctor!
  120   Fri Mar 20 17:05:58 2020 Andrey StarodumovReception testM1617 failed
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.

Interesting that the phase finding works fine, the width of the valid region is 4, so quite
good. ROC8 idneed does not give any hits but the token passed through it, so the overall
readout works fine. There re no readout errors.
The crack on the corner of this ROC is clearly visible.
I wonder how this module passed the tests in Helsinki?

For me ROC10 is programmable.
It looks like there is not token pass through ROC11.
This affects the readout of ROCs 11 & 10.
Findphases fails because of the missing ROC10&11 readout.

For me this module is working fine.
I could run phasefinding and obtained a perfect PixelAlive.
I left this module connected in the blue-box in order to run more advanced tests from home.
