Printed circuit assemblies (PCA) typically are designed on computer aided design (CAD) systems, checked, then released for manufacture. The released design description typically consists of a top assembly drawing and a series of data files which are used in various stages of manufacture. The Internet Commerce for Manufacturing Project proposed the development of a system to deliver design data in a form that could be viewed over the Internet. This paper describes the user interface developed for an Internet delivery system. Two ways to present a design using electronic hypertext media are described. The second set of electronic product data packages were validated for completeness and utility in the process of an actual procurement.
