Introduction
Surface Mount Device (SMD) assembly lines are the backbone of modern electronics manufacturing. However, with increasing miniaturization and high-speed production, ensuring the accuracy of component placement and detecting defects in real-time has become a significant challenge. Intelgic addresses this challenge with a comprehensive AI-powered machine vision inspection system designed for SMD line verification. By integrating smart cameras, configurable AI models, and defect-tracking software, Intelgic’s solution ensures flawless assembly, boosts yield, and minimizes manual quality checks.
What Is SMD Line Verification?
SMD line verification involves confirming the correct placement, presence, orientation, and quality of surface-mount components on a PCB (Printed Circuit Board) during the SMT (Surface Mount Technology) assembly process. Verification is typically required after:
- Solder paste printing
- Component placement (Pick-and-Place)
- Reflow soldering
Intelgic’s vision system performs automated optical inspection (AOI) at key stages to ensure that each component is present, aligned, and free from visible defects.
Intelgic’s AI-Powered Vision System for SMD Line Verification
Intelgic’s platform combines machine vision cameras with custom-trained AI models to detect a wide range of issues in real-time. Key components of the system include:
Camera Selection Based on Use Case
Intelgic deploys the appropriate imaging system based on the production line’s needs:
- Industrial IP Cameras: Ideal for broader field-of-view applications or lower-speed lines.
- High-End Machine Vision Cameras: Used for high-resolution, high-speed imaging, capturing micro-level defects with superior clarity.
- Line Scan Cameras: For continuous imaging of moving PCBs.
- Color Cameras: For identifying incorrect component types or color-coded elements.
AI-Powered Defect Detection Software
Intelgic’s proprietary AI engine is trained to detect:
- Missing components
- Misaligned or skewed parts
- Tombstoning and lifted leads
- Solder bridges and insufficient solder
- Foreign material or visual inconsistencies
- Wrong component type or polarity
The AI software operates in real-time, analyzing image data at pixel-level accuracy and highlighting defects with bounding boxes, heatmaps, or coordinate tags for immediate review.
Flexible Deployment Options
- Edge Processing: For low-latency, on-site analysis using local GPU/CPU.
- Cloud-Based Processing: Centralized AI model management and remote inspection reports.
System Features and Capabilities
Region of Interest (ROI) Configuration
Operators can configure multiple ROIs within a camera’s field of view to focus inspection on high-risk areas or densely packed zones.
Pixel-Level Analysis
The AI conducts fine-grained, per-pixel evaluation to detect even the smallest anomalies or missing elements—ideal for microchip and capacitor verification.
Recipe Management
Intelgic’s software supports product-based recipe management, allowing rapid switching between board types or assembly layouts.
Real-Time Alerts and Reporting
When anomalies are detected, the system immediately sends alerts, records the defect location, and generates comprehensive inspection logs.
