As the mainstream universal interface standard, Type-C connectors are widely used in data transmission and charging, common in mobile phones and computers for their high speed, large current capacity, and reversible plug-in design. Their precision internal structure includes golden fingers, metal terminals, iron sheets, injection-molded parts, and rubber rings, working together for signal transmission and physical connection.
Automated cosmetic inspection of Type-C connectors faces challenges: Ultra-dense tiny golden fingers have coplanarity issues, scratches, or contamination. High reflectivity of metal shells/terminals and plastic tongue morphology causes optical interference. Micron-level identification of subtle defects (cracks, burrs, injection flaws) is needed on high-speed lines. Traditional methods lack efficiency, accuracy, and stability for strict yield control, requiring high-precision AI visual solutions.
