Revision A of IPC-2511 (GenCAM 1.5) identifies the generic requirements for implementation of product manufacturing description data and transfer. IPC-2511A helps users transfer design requirements and manufacturing expectations from computer-aided design systems to computer-aided manufacturing systems for printed board fabrication, assembly and test. IPC-2511A establishes the rules and protocol of describing data for electronic transfer in a neutral format. The format is frozen until January, 2002. The code reference is BNF. GenCAM&trade: is documented in a series of seven major sectional standards identified as IPC-2510. All seven documents, numbered IPC-2512A through IPC-2518A, were released in November 2000. More information on the standards is available at www.GenCAM.org. GenCAM is a standardized format that is user friendly, easy to read, machine independent, cost competitive and updateable. 199 pages.
