Electronics / Concept case study

Astra Precision Vision Line

An inspection concept for small electronic assemblies, combining controlled illumination, supported presentation and identity-linked results.

01 / The brief

A consistent image. A traceable decision.

Surface finishes and component variation made reliable acquisition as important as the inspection algorithm. The design needed to distinguish a valid pass from an image that could not support a decision.

02 / Engineering response

Prove acquisition before the decision.

  1. 01

    Presentation

    Support the assembly and confirm its position and identity before acquisition.

  2. 02

    Imaging

    Select optics and illumination around the features, then test representative surface variation.

  3. 03

    Disposition

    Keep the image status, decision and assembly identity together through review and reinspection.

03 / The system

The connections
make the sequence.

Conceptual system / Astra Precision Vision Line

Physical flow, coordinated states, recorded decisions.

  1. Present boardPosition confirmed
  2. Acquire imageLighting controlled
  3. Evaluate featuresImage valid
  4. Record / routeDecision linked

Unresolved state / Hold and recover

An invalid image is unresolved. Hold the assembly for reacquisition or review and preserve its identity and original record.

From study to acceptance.

  1. Feature review

    Define the features and acceptable variation with representative samples.

  2. Imaging trials

    Evaluate lighting, optics and presentation before finalising the station.

  3. Decision validation

    Test rejects, invalid acquisitions and reinspection history.

04 / Illustrative result

What the proposed system resolves.

  • Image validity is checked before acceptance is evaluated.
  • The inspection result remains tied to the assembly through rework.
  • Representative good and defective samples define the acceptance review.

Qualitative outcomes describe the concept engineering proposal. No measured production results are claimed.
