17. Functional Test & Inspection Criteria
17.1 Sample plan
Sample plan according to MIL-STD-105D level 2, and acceptance/rejection criteria is.
Base on :
Major defect : AQL 0.65
Minor defect : AQL 2.5
17.2 Inspection condition
Viewing distance for cosmetic inspection is 30cm with bare eyes, and under an environment of
800 lus (20W) light intensity. All direction for inspecting the sample should be within 45°
against perpendicular line.
17.3 Definition of Inspection Zone in LCD
C
A
Zone A :
Zone B :
Zone C :
Note :
B
Character / Digit area
Viewing area except Zone A ( Zone A + Zone B = minimum Viewing area )
Outside viewing area ( invisible area after assembly in customer’s product )
As a general rule, visual defects in Zone C are permissible, when it is no trouble for
quality and assembly of customer’s product.
17.4 Major Defect
All functional defects such as open ( or missing segment ), short, contrast differential, excess
power consumption, smearing, leakage, etc. and overall outline dimension beyond the drawing.
Are classified as major defects.
