Defect Inspection Basics

SUMMARY

This course teaches how to design and run a defect inspection station that consistently separates “good” from “defective” across shifts and production variation. It covers defect definitions and taxonomy, why defects get missed, and how to engineer reliable inspection through lighting, optics/cameras, guided projection-based workflows, and a digital “playbook” that standardizes steps, decisions, evidence, and continuous improvement.

Main points (bullets)

• Goal: design an inspection station that consistently separates good vs defective across shifts and variation.
• Use a clear defect taxonomy (surface, dimensional, structural, assembly, functional, cosmetic) tied to specs.
• Reduce misses by stabilizing fundamentals: lighting, viewing geometry, optics/resolution, fixtures, and procedures.
• Prioritize illumination design, then select cameras/optics/filters to make defects visible and measurable.
• Use guided projection + tracking to standardize where/how to inspect and capture evidence.
• Run everything via a digital “playbook” (recipes, ROIs, steps, decision rules, outputs) to enable traceability and continuous improvement.
