THE INSPECTION CRITERIA HAS BEEN EXTRACTED FROM: REFURBISHED COSMETIC STANDARD
1.0 Objective
1.1 The objective of this document is to define the visual standards for cosmetic refurbishment of wireless handsets.
2.0 Applications
2.1 This document applies to all wireless handsets being refurbished by Motech for the self-inspection program.
2.2 This document also applies to all suppliers refurbishing wireless handsets for Motech on the self-inspection program.
3.0 Definitions
3.1 Cosmetic failure: a failure that will not render the phone in-operable, but does not meet established Motech Quality Visual Inspection Requirements for Cosmetics Procedure.
3.2 Defect Definitions:
• Burr – raised plastic that feels rough to the touch, usually along molding edges and sharp corners.
• Crack – A physical fracture in the surface of the material; plastic that has broken or is starting to break.
• Dent – A recessed spot on the surface
• Discoloration – Any change from original color or unintended, inconsistent part color.
• Fingerprints – Skin oils or impressions from handling the lens and display during the repair/refurbishment process.
• Foreign Materials – Dust or other matter inside lens or on the display.
• Gaps – Gaps between surfaces closed by self locking latches and screws. No gap more than 0.5mm is allowed unless otherwise by design.
• Glue – Residue left after removing or peeling off labels or dots.
• Lint – Foreign objects found behind Lens in the form of hairs, fibers, any particulate.
• Mar – A flaw caused by impact.
• Nick – Indentation or dent that can be felt and may/may not have raised edges
• Scaling – Residue on the metal contacts (data connector, charging connector, battery contact, SIM connector and headset sockets).
• Scratch – Singular instance of narrow long deformation in surface texture or paint surface.
• Shiny Blemish – A smoothness in the texture of the plastic, usually wide and cannot be felt.
• Smudge – Any imperfection in the surface of the lens and display.
• Spot Marks – May be any color, from pens, paints, dyes, etc.
• Stains – Foreign colorant or material.
• Texture Flaw – variation or unevenness in texture of factory finish.
• Warp – Deformation of plastic housing by bowing across flat plane.
4.0 Viewing and Inspection Process
4.1 Visual inspection is performed at arm’s length with bend at elbow (18 inches from face to device) with normal 20/20 vision (or corrected to 20/20 vision). See example below containing preferred viewing condition:
4.2 The unit should be viewed straight on and without having to rotate the unit to determine a defect.
4.3 Inspection is performed in lighting typically found in a factory environment. The type and degree of lighting is technically described as a cool, white fluorescent light source.
4.4 Entire surface of part shall be scanned once without dwelling on any single surface (approximately 2-4 seconds for each surface). Magnification is allowed only for verification of defect size. Use of tools/gauges is encouraged to aid in acceptance decisions.
4.5 Maximum defects allowed is an aggregate across all appropriate surfaces (e.g. if there are 5 class ‘B’ surfaces on a device, there can be no more than 4 defects across all of these class ‘B’ surfaces).
4.6 Final inspection of device cannot exceed more than 5 total number of cosmetic defects on the entire unit.
5.0 Surface Classifications
5.1 Surface Classification
5.1.1 AA = LCD and/or Lens(es)
a) AA surface to be inspected with unit powered off.
b) If a device has more than one LCD (ex. Flip or slide device with internal and external LCD), both LCD’s are considered AA surfaces.
5.1.2 A = front housing, front flip or slide, front cover, bezels and key pad
5.1.3 B = Sides and back housing
5.1.4 C = Interior surfaces on the back housing that will be covered by the battery or battery cover
