This standard establishes the generic requirements for a document set describing electronic products and the methodology used for revision control and configuration management of the information. The generic descriptions apply to the entire document set and are used to define and maintain the electronic product. The methodology permits different grades of completeness of the documentation and identifies various products, packaging and interconnection techniques for which unambiguous documentation is required. The requirements pertain to both hard copy and electronic data descriptions.
This standard describes the guidelines for land pattern design for all types of passive and active components, including resistors, capacitors, MELFs, SSOPs, TSSOPs, QFPs, BGAs, QFNs and SONs. The standard also provides features, including an intelligent land pattern naming convention, zero component rotations for CAD systems, and a set of three separate land pattern geometries for each component that allows the user to select a land pattern based on desired component density.
