I/O Controller for Semiconductor Wafer Processing Tool

Project description:

A major customer was building very large semiconductor wafer processing equipment with embedded controls. The equipment had multiple controllers that were cabled to large printed circuit board assemblies that provided interlock protection throughout the equipment. Assembly of the equipment required several man-weeks to run cables from the controllers to the interlock printed circuit board assembly (PCA) and then on to the various points to be controlled. The assembly was complex and prone to error. Bare boards on the equipment were often damaged in assembly.

Digital Dynamics® merged the entire control system into a single custom I/O controller. The unit included the master processing unit, controller field connect assemblies and the interlock PCA and added an on-board power supply in one integrated unit with all components enclosed in sheet metal modules. The modules were removable without tools for easy upgrade in the field. The customer cut their cabling time by 40% and hardware cost by 50% in addition to reducing scrap due to assembly issues and improving reliability of the total system.
