Industrial solution

3C Electronics

Full inspection of phones, laptops, wearables and audio products.

3C Electronics — representative inspection subject

As 3C components shrink and assemblies grow more complex, visual and conventional AOI inspection can no longer meet the required quality. DSTEK combines 2D+2.5D+3D imaging with process-specific optics and deep-learning AI to inspect every unit across the 3C process chain.

Scope

What we inspect

  • Smartphone

    Cover glass, side frame and back cover appearance; buttons, seams, ports and card slots; internal module assembly

  • Camera module

    Lens contamination and decentring, decoration staining, flash black spots, lens mounting faults

  • Laptop

    A/B/C/D face scratches and loose screws, inspected before shipment

  • Audio

    Housing scratches and colour variation, sealing faults, mesh contamination and deformation, charging terminal defects

  • Wearables

    Smartwatch band and body colour variation, black spots, contamination, scratches

  • Cover glass

    2.5D curved glass edge cracks, polishing marks and fine defects

Applications

Representative inspection tasks

A selection of what we have actually run on the line — not the full list. New inspection targets are approached the same way.

  • Smartphone exterior inspection

    Scratches, foreign matter and dents on cover glass, side frame and back cover

  • Smartphone internal module

    Missing screws, wrong assembly, missing parts, unseated connectors

  • Camera module inspection

    Lens contamination and decentring, decoration staining, flash black spots, mounting faults

  • Battery cover and fingerprint module

    Indentation, deformation, adhered particles, logo print defects, contamination trapped in the fingerprint module

  • Earphones and headphones

    Housing scratches and colour variation, sealing faults, mesh contamination and deformation, charging terminal defects

    Global smartphone OEM

  • Earphone shell and base

    Moulded surface defects and assembly condition

  • 2.5D glass edge

    Edge cracks, polishing marks and fine surface defects on curved cover glass

    Global EMS provider

  • Keyboard

    Keycap printing and surface defects, assembly condition

  • Socket and motor assembly

    Presence and correctness of assembly

  • Iron core appearance

    Lamination appearance inspection line
