Through high-magnification microscopic scanning and real-time monitoring of chemical solution parameters, this system precisely identifies micro-defects such as trace burrs, undercut, hole wall anomalies, and chemical concentration deviations. It rigorously controls product quality from both microstructural and chemical process dimensions. Specifically designed for end-of-line inspection and quality traceability in high-precision circuit board manufacturing, it serves as a core quality assurance system for safeguarding the long-term reliability and market competitiveness of premium PCB and FPC products.
