First Electrical Hybrid Panel

The first hybrid panel for electrical prototypes came on Nov. 29th 2016 from USCS/SCIPP. It came with 8 hybrids ver 1.1, 4 left handed and 4 right handed hybrids. Digging through the Liverpool documentation this is likeley the Stevenage 5 hybrid panel (https://hep.ph.liv.ac.uk/twiki/bin/view/CleanroomTestStands/ABChcc)

The list of passive components for the hybrids is https://hep.ph.liv.ac.uk/twiki/pub/CleanroomTestStands/ABChcc/SMD-components_V2.pdf (Dec 1st 2016)

The official documentation page for this is under https://twiki.cern.ch/twiki/bin/viewauth/Atlas/ABC130ShortStripsHybridLiverpool

The wire bonding diagram used for this is https://twiki.cern.ch/twiki/pub/Atlas/ABC130ShortStripsHybridLiverpool/Hybrid-Wire-Bonding_V1.pdf (Dec 5th 2016)

Documentation

New Capacitors:

Liverpool_hybrid_end.jpg

All hybrids came with misplaced C7-C12, either none were placed or all had incorrect alignment. Similarly every hybrid had RP1 and RP2 with incorrect orientation.

NTC2 Orientation

Misplaced_NTC.jpg

On hybrid 0 and hybrid 1 the NTC2 is incorrectly soldered. Instead of connecting the pads on both sides it sits vertically on one pad
