The introduction of the flat pack as a circuit element stimulated development of techniques for attaching flat packs to mother boards. The problems inherent to this development program are summarized and discussed. Design and operation of a flat pack welding system is presented. Various approaches to automated flat pack welding are reviewed, and the advantages and disadvantages of each are discussed. The final design for an automated flat pack welder is presented with a discussion on the operational functions of the major components of the system.
