When micro-defect control matters in PCB defect inspection — what’s your approach?

Precision and accuracy in inspection are essential to ensure PCB quality.

With PCB patterns becoming increasingly fine and complex, visual inspection struggles to catch small defects like opens, shorts, or pinholes. But just one defect can cause overheating, short circuits, or performance loss — which is why quality assurance is critical.

SAIGE VISION Inspection Areas
in PCB Manufacturing

  • PCB Substrate Quality Inspection

    In PCB substrate manufacturing, this stage ensures the quality of structural elements such as circuit patterns, layer alignment, drill holes, solder mask, and overall appearance. SAIGE VISION identifies even the smallest defects — from micrometer-scale alignment errors to subtle pattern flaws — at high speed and with exceptional accuracy. For high-density PCB production, AI-driven inspection is now essential to boosting both quality and productivity.

    • 내층 회로 검사 (Inner Layer Inspection)

      Inner Layer Inspection

      • Detects defects like line breaks, shorts, and micro dust that can occur during copper layer formation via photoresist exposure and etching
      • AI identifies qualitative defects such as scratches, dents, and unplated areas that rule-based methods may miss
      • Compares etched inner layer patterns to design files (Gerber) to ensure accuracy
    • 드릴 검사 (Drill Inspection)

      Drill Inspection

      • Detects key PCB drill defects like misaligned holes, contamination, and incomplete plating
      • Uses AI classification to reduce misclassification common in rule-based systems
      • Enhances hole images for more accurate defect detection
    • 최종 외관 검사 (Final Visual Inspection)

      Final Visual Inspection

      • Checks overall PCB surface, foreign materials, contamination, and printed markings before packaging
      • AI-powered segmentation detects defects that rule-based systems may miss
      • AI-based detection algorithms accurately identify and classify defects such as dents, scratches, insufficient plating, and contamination.

  • PCB Assembly Inspection

    In PCB assembly inspection, SAIGE VISION ensures defect-free production by verifying precise component placement, detecting missing parts, and identifying soldering issues at every stage — from solder paste application to final connections. Powered by AI, it outperforms traditional methods even under reflective or changing lighting, delivering real-time feedback to fix errors instantly and cut defect-related costs.

    • 솔더 페이스트 검사 (SPI, Solder Paste Inspection)

      Solder Paste Inspection (SPI)

      • Inspect solder paste position and shape for closed-loop control in PCB screen printing
      • Real-time quality inspection to detect printing issues and provide early alerts on deviations
      • Measures solder paste height, area, and volume, and detects misalignment using 3D scanning and deep learning
      • Detects defects such as sunken or raised prints, bridging, and peaking
    • Capacitor Soldering Inspection

      Capacitor Soldering Inspection

      • Uses supervised learning to detect micro defects in soldering that could cause wire breakage, shorts, or other electrical issues
      • Identifies PCB resist positions and detects functional abnormalities such as bridging, peaking, and spacing variations
      • Inspects solder defects affected by light reflection that alter perceived size, shape, or form
      • Deep learning-based method quickly identifies solder resist on diodes under industrial lighting conditions
    • 부품 배치 검사 (Component Placement)

      H4 Component Placement Inspection

      • Detects and corrects component position, orientation, and missing parts in real time during SMT (Surface Mount Technology) processes
      • Checks alignment accuracy of fine-pitch components critical to PCB performance and longevity
      • Performs inspections under subtle lighting contrasts, perspective shifts, directional changes, and reflective metal surfaces
USP

SAIGE VISION — Specialized in PCB Quality and Assembly Inspection

  • Defect Generation Function That Enables Accurate Detection of Low-Frequency Defects

    • Various types of defects can occur during PCB manufacturing processes. For defects with low occurrence frequency, defect data collection is challenging, and detection performance may deteriorate due to insufficient training data
    • By utilizing the Defect Generation function, virtual defects similar to low-frequency defects can be created and used for training, thereby improving detection accuracy for these defects

  • Image Comparison Function That Detects Defects by Comparing with Design Data

    • Defects occurring in circuit patterns such as open circuits and short circuits can directly impact PCB performance, making accurate defect detection crucial
    • SAIGE VISION enables precise circuit pattern inspection through a feature that compares design data with vision images
