A high speed high precision laser based alignment sensor system for use on surface mount component placement machines. A laser system is utilized to correctly align and position component parts which range between 0.02 inches and 2.0 inches in size. The laser sensor system consists of a laser light source which is passed through a collimating lens and then through an aperture to create a stripe of collimated laser light which is focused past the component being aligned to strike a multi-element CCD sensor array. The sensor system is mounted directly on the carrying mechanism for the surface mount component placement machine. During transit of the component between the bin of components is to be placed, the component is rotated and the shadow which falls on the detector array is monitored. When the minimum width of shadow is detected, the correct angular orientation is determined, the average of the edges of the shadow when compared with the center of the quill determines the coordinate (X,Y) location of the component on the quill. Two alignments normally occur displayed by 90°. Thereafter, the sensor sends correcting signals to the component placement machine to assure the correct angular orientation and the correct X,Y position for the component to be placed on the circuit board by the component placement machine.

An improved electromechanical RF switch provides enhanced reliability and lifespan by incorporating a middle plate between the case and base elements for locating the guide pins, reed holders and reeds to increase accuracy in critical component alignment. The middle plate reduces required precision during assembly of the switch, thus increasing assembly accuracy while reducing labor cost. The guide pins are made of a hard insulator such as glass to generate less wear particles, and the reed holder has a groove filled with lubricant to trap any wear particles that result from sliding friction during switch operation. Optionally, a low-friction bushing is used within the case bore to further reduce sliding friction during reed holder travel. The reeds are made of thin, flexible metal and have ends shaped so that when the ends contact switching terminals, a wiping action removes any surface contamination from both the reed ends and the terminals.
