Completely break the shop-floor habit of "mass-producing while the first article fails." Production starts only after the first article passes, patrol-inspection failures auto-stop the line, and final-inspection data binds to shipping orders; inspection items are configurable, results leave an audit trail, and defective items are traceable — the three-check system truly lands on the floor.
From the first article at start-up to final inspection at line-off, every inspection action has a digital closed loop
After every start-up / changeover / material change, a first article is mandatory; mass production proceeds only when OK, while NG auto-blocks the start button
Patrol reminders by time or count frequency, with inspection tasks pushed to the PDA; overdue tasks auto-alert the supervisor
Sampling before line-off, with the sample size auto-calculated per the AQL sampling plan, and results bound to the shipping order
Appearance, dimension, performance and reliability item categories, with three data types: variable / attribute / option
A patrol NG triggers a line-stop signal and pushes an Andon call; production cannot continue until it's handled
Take photos during inspection and read values directly from gauges, avoiding manual transcription errors, with traceable results
"Keep running even though the first article fails" is a common shop-floor hazard — often it means a whole batch of scrap. The system enforces it: until the first article is submitted and IPQC judges it OK, the "Start" button on the worker's PDA is unavailable, eliminating this risk by design.
The biggest problem with patrol inspection is "forgot today," "too busy tomorrow." The system proactively pushes patrol tasks to IPQC at the frequency the process requires (every 2 hours / every 100 pieces); overdue tasks auto-alert the supervisor, ensuring no patrol is missed.
Final inspection isn't just a pass/fail judgment — it samples per the customer's AQL (acceptable quality limit) plan. The system auto-calculates the sample size and acceptance limits per the customer's standard; after OQC enters data, it auto-judges pass / fail / re-inspect.
A first article + retained sample is mandatory at every die start / die change; an NG first article auto-locks the batch for later traceability
5 boards sampled for X-Ray every hour, with solder-joint defect data fed back to SPC to prevent batch cold joints
High appearance requirements mean 100% visual inspection after line-off + AI vision assistance, with defect codes auto-classified
Scheduled patrol of temperature/humidity, pH and cleanliness per HACCP critical control points, with records archived for reference
Inspection data drives SPC, the defect workflow and quality traceability
