Development of the ability to automatically assemble surface mount devices on circuits is described, including the characterization of the assembly process and improvements made to the system to increase the accuracy and repeatability of this process. The accuracy and repeatability of the system were characterized by measurements of the individual system components as well as the actual placement of components on a specially designed gauge. The forces and stresses experienced by the components when handled by the system were analyzed. The ability to deliver surface mount components to the system was developed by the design and development of stick magazines, vibratory feeders, a feeder control system, and an automatic stick magazine loader
