Final Product Inspection (FQC)

Final Product Inspection (FQC)

You run QA at an electronics contract manufacturer. QC inspectors use paper checklists and red-pen annotations on printed reference photos. A data-entry clerk types defect data into the QMS at shift end. Lag between inspection and data entry: six to eight hours.

Paper-based QC creates latency that masks real-time quality trends. A defect pattern at 8 AM doesn't appear in the QMS until 4 PM — hours of potentially affected production. Handwritten annotations are inconsistent — one inspector's "scratch, minor" is another's "surface abrasion, acceptable." Checklists get lost or coffee-stained. When an auditor requests last month's records, someone digs through filing cabinets for 45 minutes. Red-pen annotations can't show visual defect trends over time.

LonTon Solution

Deploy a Lonton 65-inch or 75-inch 4K UHD panel at each QC station. Replace printed photos and paper with a digital inspection interface on Android 13 or Windows 11 via the OPS slot. The LG IPS panel at 3840×2160 renders reference images, CAD overlays, and inspection criteria at grain-level detail. Anti-glare tempered glass (MOHS 7) stays readable under bright task lighting. 40-point IR touch lets inspectors annotate directly — circle defects, classify from a palette, add notes. Data writes to the QMS in real time — no lag, no transcription errors. 350 cd/m² brightness for inspection-booth conditions. Anti-dust enclosure protects against flux residue and shop dust. Multi-source input switches between a digital microscope feed and reference panel with a tap. RS-232 control wakes the panel when the station is occupied.
