Andrey Starodumov | General | ROC4 or ROC12 defects | Starting from M1650 almost every module has
a cluster of dead pixels or broken bump bonds

Andrey Starodumov | Full test | FT of M1623, M1657, M1673, M1674 | M1623: Grade B due to rel gain width, in ROC4
74 pixels failed trimming (Threshold) and
mean noise >200e

Andrey Starodumov | Change TBM | Change TBMs on M1635, M1653, M1671 | M1635: no data from ROC8-ROC11 => change TBM1
M1653: ROC12-ROC15 not programmable => change
TBM0

Andrey Starodumov | Full test | FT of M1662, M1675, M1676 | M1662: Grade C due to failure of ROC4 in almost
all tests: PixelAlive, PH calibration etc
Should be investigated and retested. At Reception |

Andrey Starodumov | Full test | FT of M1542, M1557, M1630, M1649 only at +10C | M1542 has grade C for relative gain width.
Was tested with early versions of test SW
with trim VCal=40 and not yet optimized PH |

Andrey Starodumov | HDI test | 4 HDIs tested | After staying in 90%+ RH 2 HDIs became flat.
The first one was easy to mount on an HDI
holder.

Andrey Starodumov | General | Retesting starts today | From today we will retest modules that have
been tested with pXar SW versions earlier
than March 18.

Andrey Starodumov | Full test | FT of M1542, M1554, M1555, M1653 | M1542: Grade C due to massive (>1000pixels
in total) trimming failures at -20C in ROC11,14,15.
There was no such problem at previous test |

Andrey Starodumov | HDI test | 11 HDIs tested | After keeping HDIs in a very high RH for a
dew hours (24 is fine) became flat and could
be fixed on HDI holder by vacuum.
