Hybrid Seven (First Electrical Hybrid Panel)

Line: 35 to 35
  Suggestion from Ashley that only 2 of the padterm pads are needed (padterm being the additional bonds on the 3 ABC130 chips furthest from HCC). Apparently Chip ID is more stable with 2 of these bonds. Removed padterm bond on chip 18. Tests run concurrently with tests for HybridOne on March 2nd.
Results from QC for hybrid are included below:

  Hybrid 7 was moved to TM panel for storage on March 9th, 2017.
Results show multiple low gain and high offset channels, the hybrid was moved back onto the panel on __ for further testing. There is a further voltage drop in the panel itself, so to get 1.5 Volts on the hybrid the power supply needs to be run at 1.65 Volts. The further 3 Point Gain scan is included below:


These scans show no low gain channels, however the "wonky gain" still appears on chip #3 (indexed from 0). Talking with Craig about this it appears that there is a voltage drop in the hybrid for the connection of that specific chip.
