ETS - Offline AOI
Overview
The Inspection System is a versatile, high-precision solution designed for PCB quality control across all stages, including after stencil printing, pre/post reflow oven, wave soldering, and FPC inspection. It supports manual and automatic programming with CAD data importing and features advanced defect detection for stencil printing, components, and soldering issues. Using template matching, color calculation, vector analysis, grayscale operation, and OCR/OCV, it ensures accurate inspection of even the smallest components, down to 01005 chips and 0.3 mm pitch ICs. The system combines high-speed cameras, customizable lens resolution, and multi-channel annular lighting with flexible PCB handling, servo-driven XY movement, and precise positioning. With full SPC data recording, array and bad-marking functionality, multi-language software, and optional features like maintenance stations and barcode systems, it delivers reliable, efficient, and fully traceable quality control for modern SMT production lines.
- Detects stencil printing defects, component misalignment, missing/excessive parts, soldering issues, and more.
- High-speed cameras (5MP standard, 20MP optional) with customizable lens resolution and multi-channel annular lighting.
- Servo-driven XY movement, automatic/manual PCB loading, adjustable board size, thickness, weight, and component height.
- Supports template matching, color calculation, vector analysis, grayscale processing, OCR/OCV, and other advanced inspection algorithms.
- Full PCB coverage, array, and bad-marking function, with full data recording and statistical analysis for production monitoring.
