Work performed by NIST's Electronics and Electrical Engineering Laboratory has helped the Navy's ManTech program describe electronic circuit packages in a computer-sensible form. One such assembly, the hybrid microcircuit, has many characteristics that are typical of both printed-wiring boards and integrated circuits.
The NIST/Navy project has led to a new American National Standards Institute standard for the transfer of product data for these circuits. The standard, expected to be published in May 1997 by the U.S. Product Data Association as "ANS US PRO/UPO-111-1996" should facilitate error-free transfer of electronic product data between computer-aided design programs via the Initial Graphics Exchange Specification. It also will improve electronic product data transfer between CAD and computer-aided manufacturing programs.
The standard provides a means of data exchange that permits engineers to concurrently design electronic packages, including hybrid microcircuits, despite different, normally non-communicating CAD tools. In addition, the new standard reduces the chance of error between the design and manufacturing steps.
