Bare module probing tests visual inspection? FE probing (subset of standard test routines ATL-IP-QC-xxxx): ● global- & pixel register functionality ● column pairs affected by pixel defects ● pixels not answering to digital injection ● pixels with low noise (without HV to sensor) ● analogue and digital current consumption at power up, after global registry test, after digital injection scan & after noise scan ● MonLeak ? ● CrossTalk ? sensor probing: ● standard I-V measurement (ATL-IP-QP-0006)

Glue bare module to flex hybrid equip. ● 10 sets of module mounting tools (doesn't exist - construction drawings ready) ● stereo microscope (exists - maybe new or additional light source needed) ● Dow Corning SE4445 silicon and Dow Corning 3140/3145 ● glue rotator (doesn't exist - easy to build) ● glue and vacuum apparatus with accessories (exists - Paggen LABSET M- Dispenser & M- VAC-PIN) ● 3 different glue methods used (discussion last pixel week - wait for decision) ● heater (exists - Heraeus) Bond FEs to flex hybrid at Bonn ● automatic bonder at Bonn ● trip to Bonn when all module mounting tools are filled or we need a extra chuck at Bonn and some flex holder protection tools
