Precision Optoelectronics Assembly Consortium

Final Report of NCMS Project No. 160206 (September 1999)

Optoelectronics merges optics and electronics to fuel an exploding market segment of the U.S. electronics infrastructure, a segment that enables the production of devices such as flat panel displays for laptop computers and small laser transducers that extract sound from an audio CD. In global competition for the sale of these devices, the cost of assembly is a critical determinator of market share. This report describes the steps taken and the progress made in developing the enabling technologies to build low-cost, flexible, automated equipment to assemble optoelectronic devices. Among the technologies developed and described in the report for high-precision assembly are a virtually frictionless, magnetically supported positioning lead screw; low-cost, sensor-based assembly platforms; micro stages; active vibration control; and high-precision 3D machine vision for automated assembly. Examples are given that describe how these flexible technologies can be combined to address a variety of assembly requirements.
