Vision System 9-1

9 Vision System

Overview

The Century C-721 dispensing system is equipped with Asymtek’s Pattern Recognition System (PRS),

incorporating a vision processor card, for detection of die edges and local and global fiducials. Aided by

lighting appropriate to your application, the system provides increased process reliability, accuracy, and

yield, and is fully compatible with Asymtek’s Fluidmove for Windows NT (FmNT) dispensing software.

This section describes how the vision system works and how to operate it. For information on how to

program your vision system using FmNT software, see the Fluidmove for Windows NT User Guide.

The vision system for your Asymtek dispensing system is installed at the factory. If you upgrade to a new

dispensing system or need to remove any components, consult the appropriate dispensing system

installation manual or contact Asymtek Technical Support.

Two light source options are available for accurate location of fiducials on printed circuit boards and

components: standard NER Diffuse On-Axis Light, or optional Light-Emitting Diode (LED) Light Ring.
