Dominion Electronics’ Digi technology for network integration of asynchronous devices

Digi technology for network integration of asynchronous device
In the semiconductor industry, accuracy is defined in microns. With such a microscopic margin for error, the automated production inspection of silicon wafers is a demanding machine vision application.
Semiconductor process control systems combine highly accurate optics, precision mechanics, sophisticated image/data analysis software and an array of other measurement controls to automatically identify, measure and classify defects on processed wafers.
The results are used to resolve underlying process or equipment issues, and to increase production output and quality.
A manufacturer of semiconductor process control systems was designing a new generation product based entirely on network communication.
All vital measurement and control components inside the complex system needed to be tied to the central processor through an internal Ethernet network. The challenge was the cost-efficient and reliable network integration of components that utilise asynchronous interfaces.
The Digi technology from Dominion Electronics was quickly and seamlessly integrated into the process control system. Advanced serial-to-Ethernet features applications to communicate transparently with serial devices over an IP network.
The Digi equipment allowed the manufacturer to deliver the new generation of reliable, network-enabled products, without impacting production time and cost.
