Shop floor control in ASIC assembly

The paperless integrated manufacturing system (PIMS), a tandem-based shop floor control system, and its implementation in ASIC (application-specific integrated circuit) final manufacturing are discussed. The lot tracking and data collection features of PIMS are reviewed. Production problem solving that utilizes a structured query language (SQL) to analyze the collected data is described. Two online SQL reports and their applications are presented to show the effectiveness of the ASIC shop floor control program.<
