Abstract: A method of optically inspecting a fastener to determine whether it meets two or more dimensional parameters is provided. The method includes using centrifugal force to place the fastener in a predetermined location. Two or more sets of image data of the fastener are generated from two or more corresponding different angles. Fastener pass/fail data is generated using a dimensional requirement associated with each set of image data.

Abstract: A system for inspecting components is provided. The system includes a CMOS imaging system generating image data, such as pixel data from a pixel array. An image analysis system is connected to the CMOS imaging system, the image analysis system receiving the image data and generating image analysis data. The CMOS imaging system generates the image data at a rate that allows the CMOS imaging device to be used for inspecting components.

Abstract: A system for inspecting a component is provided. The system includes an imaging system, such as a digital camera. A controller is connected to the digital camera. The controller receives the digital image data of a device that is generated by the camera. The controller processes the digital image data to generate control commands. A variable grid generation system is also connected to the controller. The variable grid generation system can receive commands from the controller, and can generate a grid in response to the commands that matches the component and that allows the component to be inspected.

Abstract: A variable intensity lighting system for use with a machine vision apparatus for capturing high contrast images of articles to be inspected, such as semiconductor packages, includes an LED or optical fiber element and flash lamp array configured in multiple segments which are operable to be controlled as to light output intensity by a programmable intensity control circuit operably connected to a microprocessor. The intensity control circuit includes multiple digital potentiometers operable to control selected segments of the lighting array. The control circuit is adapted to control up to 64 segments of the lighting array individually at 64 incremental intensity levels, respectively. The control circuit may include a light failure module to detect a segment failure or a reversed connection.
