Practical guidance on automated end-of-line inspection from the Eolvision team.
We walked through the books of three Ohio-area stamping suppliers. Here is what automated EOL inspection costs, what field escapes cost, and how the math works out over 18 months.
Three integration paths, three different tradeoffs. Which one is right depends on your MES, your PLC, and how much real-time feedback your line control system needs.
Rule-based inspection works well for dimensional checks and known defect geometries. Neural classifiers handle ambiguous surface anomalies better. The answer is rarely either/or.
Section 8.6 on control of nonconforming outputs. Section 8.7 on customer escapes. What automated vision inspection data you need to retain, and in what format, to satisfy an IATF audit.
Coaxial lighting for solder joint gloss. Area scan vs line scan selection. How many images you actually need to train a reliable joint classifier. Lessons from three electronics contract manufacturer deployments.
A 2% false reject rate on an 800-unit-per-minute line costs you 16 good units every minute. How to tune your vision model thresholds to hit <0.3% false reject without increasing escape rate.
