Panel Procurement Inspection (Giorgio slides)

• Panel Procurement Status
• Received and Inspected 600 5x12 Panels (out of
  1500)
• Received and Inspected 200 4x12 Panels (out of
  500)
• After some initial definition of tests we
  converged on the following QC steps
• Make Laser flatness measurements on 3 of the
  panels
• Screen 100 of the panels with a Pin Gauge

TD database - Alignment marks -Summary
For 40 of ME234/2 panels (already made at
LAB8), overall quality of Panels (based on
alignment marks analysis) is very good.
