One defect model across every SMT line

AOI, SPI and test each hold part of the truth about a board. When those datasets stay separate, the same defect is investigated repeatedly on different lines. The platform unifies them into one board-level model, so a shared root cause is visible the first time it appears.

Where the cost sits

The problems we start from

These are the recurring findings from discovery workshops in this sector. If none of them describe your operation, a pilot is probably premature — and we will say so.

Operational problems

  • Repeat defects across lines go unnoticed

    Each line investigates its own AOI data, so a stencil or reflow issue affecting six lines is treated as six separate problems.

  • False calls consume operator time

    High AOI false-call rates train operators to override, which erodes confidence in the inspection system itself.

  • High mix makes trends invisible

    Hundreds of assemblies per month mean per-product volumes are too small to see a trend without normalising across products.

  • Customer-specific reporting overhead

    EMS customers each want their own quality reporting format, produced manually every month.

Engineering constraints

  • Very high mix, low volume

    Analysis has to normalise across assemblies and components rather than assume long production runs.

  • Multiple inspection vendors

    AOI, SPI and X-ray systems from different vendors expose incompatible data structures and defect taxonomies.

  • Component-level traceability

    Tracing a failure to a reel, feeder and placement head requires machine-level data most reporting tools discard.

  • Fast changeovers

    Several changeovers per shift mean setup-related defects dominate, and they only show up if changeover events are captured.

Platform capabilities

How the platform is configured for electronics & ems

Same architecture, same modules — configured against the characteristics, sampling logic and evidence expectations of this sector.

Unified defect taxonomy

Normalises AOI, SPI, X-ray and test outcomes into one board-level defect model so cross-line patterns become visible.

False-call reduction

Learns from operator verdicts to separate genuine defects from nuisance calls, and reports the false-call rate per station.

Process-window monitoring

Paste volume, placement offset and reflow profile monitored as a window rather than as isolated pass/fail checks.

Component and reel traceability

Links defects to reel, feeder, nozzle and placement head to expose equipment-specific causes.

Customer reporting packs

Scheduled per-customer quality reports generated from live data instead of assembled by hand each month.

Typical integrations
  • Koh Young AOI
  • Cognex
  • Siemens Opcenter
  • MQTT
  • Power BI
  • Jira

Expected ROI

A value case your controller can interrogate

Every line below is an assumption, not a promise. During a pilot each one is replaced with a measured figure from your own baseline, which is what makes the business case defensible in a capital review.
