The PCB Automated Visual Inspection (AVI) System is an advanced optical inspection solution designed for pre-shipment final quality control in printed circuit board manufacturing. Integrating cutting-edge image processing, artificial intelligence, and real-time computing technologies, the AVI system automatically detects surface defects and cosmetic imperfections on PCBs with high speed and precision.
As an intelligent vision-based inspection system, AVI replaces traditional manual visual inspection—which is prone to human error and fatigue—with automated, non-contact inspection that is faster, more consistent, and more accurate. The system is widely used in high-volume, continuous automated production lines for online, non-contact inspection and monitoring.
The AVI system can detect a comprehensive range of surface defects across various PCB surface finishes and board types:
| Category | Defects Detected |
|---|---|
| Solder Mask | Ink buildup, contamination, scratches, missing print, exposure shift, exposed copper |
| Legend / Character | Blurred printing, missing characters, wrong characters, extra printing, wrong color, misalignment |
| PAD (Land Pattern) | Scratches, oxidation, solder mask contamination, nicks, residual copper, contamination, uneven surface |
| Hole / Outline | Missing drill holes, plugged holes, missing routing |
| Gold/Copper Surface | Protrusions, dents, shorts, opens, foreign objects, contamination, missing plating, scratches, nicks, bumps, exposed copper, misalignment |
| Surface Finishes | Supports ENIG (Electroless Nickel Immersion Gold), OSP, Immersion Silver, Immersion Tin, and HASL (Hot Air Solder Leveling) boards |
| Special Features | Selective area inspection (e.g., BGA areas, gold finger seepage detection); customizable detection functions |
Supported board types include rigid PCB, flexible PCB (FPC), rigid-flex PCB, HDI, CSP, BOC, MMC, BGA, IC substrate, and automotive PCB.

The AVI system is specifically designed for final visual inspection of PCBs prior to packaging and shipment. Its core purpose is to identify and sort out defective boards before they leave the factory, thereby:
Reducing product scrap and rework costs
Minimizing customer returns and complaints
Ensuring consistent product quality
Lowering reliance on manual labor and reducing human inspection costs
