Part Information
Dimensions:Sample parts are 32mm x 28mm.
Both dimensions have a tolerance of +/- 0.20mm.
Parts are 0.7mm thick on display grade glass substrate.
Transmission Orientation is parallel to the long side
Visual Inspection:
All sample parts will be inspected to Visual Quality Grade 2
Clear Aperture:
Parts are only inspected within the clear aperture. This is the useable area of the part. The
clear aperture is the part minus an edge exclusion on each side. Sample parts have an edge
exclusion of 2mm.
