Setup for module production QA (last update 21/9/2016)

There are two tests:

1. quick electrical test ("20 seconds"), mainly to check that wirebonds are ok. This test should take place in the clean-room. For this we need:

• LV (incl. PC for controls?)
• DAQ
• fibres to connect to DAQ
• database to summarize results

2. burn-in test ("24 hours"). For this we need:

• LV
• HV (till 1000V; must have precise current control/monitor )
• PC with PVSS to control LV and HV
• DAQ
• fibres to connect to DAQ
• PC to run data analysis (needs to happen in real time as data volumes are very large)
• database to summarize results
• 19 inch rack
• CO2 cooling
• vacuum tank
• if not in the cleanroom, a 'tent' to protect setup

Rough schedule:

• Q4 2016: prepare vacuum tank, cooling
• Q1 2017: prepare DAQ
