• Perhaps the most important current effort to develop neutral representations of product data is STEP (ISO 10303).

• Since its Initial Release in March of 1994, new STEP parts and numerous application protocols are being developed.

• Application Protocols (APs) are information models that specify the structure of the data for the exchange of information between applications of a specific domain.

• STEP and its textual conceptual schema language EXPRESS were selected for this research because they provide the neutral mechanisms for describing and exchanging product information and because there are several development tools commercially available to aide in the development of STEP applications.

• This slide shows the main groups of information contained in AP210 (“Printed Circuit Assembly Product Design Data”).

• AP210 defines the information shared between design and manufacturing process planning engineers for transforming a PCA detailed logical design into a manufacturable description.

• The detailed logical design identifies the PCA components and the connections between those components.

• The manufacturable description describes the physical realization of that logical design.

• This AP includes information about products that is sufficient to allow their use as components of a PCA, as well as information needed to support configuration management of the PCA product data.
