Production Test Station Networking and Collection of Test Results

This thesis describes the installation of a network for all of the final test stations at the Industrial Systems Division of Texas Instruments in Johnson City, Tennessee. Once the network was installed, the project focused on the automatic collection of the test parameters for a centrallized database. The database was used to generate statistical data to determine if the manufacturing process were in control. If the process were not in control, then appropriate action was taken to prevent the particular unit from being tested. This provided a accurate and real-time analysis of how the manufacturing process was performing. Also, the automatic collection provided a means of studying how the manufacturing process performed over a period of time.
