TE 8000 – Wafer Stencil Inspection System

This project is continue research and enhanced from ASIS PCB, Advance Stencil Inspection System in order to achieve new capabilities:
- System able to inspect 1 million apertures, with 1 time scan 8x8 inch wafer disk, by 3200dpi resolution and its accuracy achieve 7um
- System able to inspect 1 million apertures, with 1 time scan 12x12 inch wafer disk, by 2400dpi, resolution and its accuracy achieve 11um

* This project was awarded with entrepreneurship (CIP) grant by CRADLE in year 2008
Research & Developed Prototype In Inspecting Wafer Stencil (Die by Die Inspection) Demonstration:




Green color spot show dust / stain appear on wafer stencil, red color spot shows missing apeature detected.

Due to the wafer stencil surface is dirty, system detect a lot of stain from the image captured. Further research and implementation on hardware and software are required to reduce the errors detection.
