Standard Quality Control (QC) Process for Apple Spare Parts

1. IQC: Incoming Quality Control
Visual Inspection: Check the external packaging for damage. Inspect the glass for scratches, cracks, corner chips, or coating (anti-reflective) peeling.
Specification Matching: Verify Model Number, Resolution, and Connector type (e.g., EDP 30/40 pin) against the PO.
Backlight Inspection: Check the backlight sheets for creases, debris, or "white spots."

2. IPQC: In-Process Quality Control
ESD Protection: All technicians must wear anti-static wrist straps and gloves.
Cleanliness: Sorting and testing must be performed on a Dust-Free Workbench to prevent dust ingress.

3. FQC: Final Quality Control (100% Functional Test)
This is the most critical step. Every screen must undergo a full diagnostic.
Pixel & Color Test: Switch between solid colors (Red, Green, Blue, Black, White, Grey).
Check for: Dead pixels, bright spots, light leakage, or color tinting.
Brightness & Flicker: Adjust brightness from 0% to 100% to ensure stability.
Sensor & True Tone: For newer MacBooks (T2/M1/M2/M3), verify the sensor cable's integrity for True Tone and Auto-Brightness functionality.
Cosmetic Grade: Categorize as Grade A++ (Perfect), Grade A (Minor flaws), or Grade B.

4. OQC: Outgoing Quality Control
Warranty Sealing: Apply a tamper-evident Warranty Sticker with the production date.
Secure Packaging: Use specialized bubble bags, anti-static bags, and high-strength foam boxes.
Final Verification: Cross-check the Serial Number (SN) on the part with the shipping invoice.
