PCB Automatic Visual Inspection Machine

AVI System for Bare Board Surface Defect Detection

Inline Visual Inspection System | CCD-Based Automatic Optical Inspector for Bare PCB Appearance Defect Detector

Key Features

S25 Inline PCB AVI Visual Inspection Equipment

This is a high-precision AVI (Automated Visual Inspection) system designed specifically for PCBs (Printed Circuit Boards). It is primarily utilized for the automated visual inspection of bare PCBs—examining the boards' surface appearance prior to the mounting of any components.

Inspection Objects: Bare PCBs (devoid of any components) | Suitable for integration into PCB manufacturing processes
Inspection Method: Supports importation of Gerber data | Performs comparative analysis between Gerber data and actual physical PCB product
Inspection Scope: Surface scratches | Silkscreen character verification (missing, blurred, contaminated, or misaligned characters) | Surface finish anomalies (oxidation, contamination, defective coatings)
Inspection Capabilities: Supports simultaneous inspection of both PCB sides | Automatically renders inspection verdicts and generates comprehensive reports

This equipment combines traditional image processing techniques with optional modern AI algorithms, addressing critical industry pain points such as difficulty detecting minute defects, high false-alarm rates, and inefficiency of manual re-inspection.

Core Functions and Applications

High-Precision Circuit Inspection: Suitable for detecting circuit defects—including short circuits, open circuits, burrs, and notches—across various PCB types such as gold-plated, OSP-finished, hot air solder leveled (HASL), and silver-plated boards. Optimized for boards ranging from 0.3mm to 5.0mm thickness and supports auxiliary inspection of flexible PCBs (FPCs).

Dual-Mode Defect Judgment: Employs "Image Comparison + Logic Calculation" algorithm as core foundation to ensure high detection rate for common defects. Optional "AI Intelligent Filtering" module utilizes artificial intelligence to filter out false calls caused by surface process artifacts. Official test data indicates false-call filtering rate exceeding 70%, significantly reducing operator verification workload.

Automated Inline Operation: Supports automatic board loading/unloading and dual-track/dual-panel inspection. Integrates into production line via horizontal conveyor belt system, automatically aligning and staggering boards for fully automated, unattended production.

Offline Re-inspection and Repair (VRS): Equipped with dedicated Verification and Repair Station (VRS). When defects are detected, system records coordinates; operators use re-inspection station to quickly verify defects via high-definition imagery and perform repairs directly on physical board, minimizing production line downtime.
