Circuit Board Scanning


Application Description
An Original Equipment Manufacturer (OEM) manufacturer's X-Ray Scanning equipment is used in the quality control of printed circuit boards and wafer chips.
The OEM wants to replace the DC motors, mechanics and analog controls with an automated PC-based system to increase throughput and eliminate operator error. The host computer will interact with the motion control card using a "C" language program. The operator will have the option to manually override the system using a joystick.
An Original Equipment Manufacturer (OEM) manufacturer's X-Ray Scanning equipment is used in the quality control of printed circuit boards and wafer chips. In this application an automated PC based system replaces the existing system thereby increasing throughput and eliminating operator error. Moreover the operator has the option of manually overriding the system.
