Design-to-manufacturing information management for electronics assembly

This paper addresses design to manufacturing (DTM) for electronics assembly from several different perspectives. First, a working definition for DTM i s proposed, and the distinction is made between DTM and the more commonly k nown design for manufacturability. Following an overview of surface mount t echnology assembly processes, DTM information management is introduced in t erms of its data requirements and underlying decision and planning problems . Evaluation criteria are discussed, and specific requirements for a state- of-the-art DTM system are highlighted. The experiences of one Motorola fact ory are presented in a brief case study, which covers process mapping, syst em design and benchmarking, and installation and configuration activities. Benefits of an efficient DTM sytem are discussed in terms of the improvemen ts in production time, engineering time, and product or process quality. Fi nally, a summary of future trends for DTM is given.
