WI-6500 Automatic Wafer Defect Inspection System

WI-6500 Automatic Wafer Defect Inspection System
WI-6500 Automatic wafer defect inspection system is consisted of machine vision inspection system, automatic loading and unloading system, automatic inspection system and control software.

The system supports automatic defect inspection of 25 wafers (1 cassette). It can detect the number and position of wafers in the wafer cassette, quickly detect the defect position, extract the defect image, and fifinally generate the defect map. The results are stored in the system database of the production line for operators and engineers to analyze the defects of the products.

Compared with manual inspection, this system has obvious advantages. It can perform long-term high-precision and high-efficiency inspection with high accuracy, which can greatly improve produc tion efficiency and inspection accuracy, reduce costs and increase efficiency for customers.
