We do not use IPC 9850.
�The stated purpose of IPC 9850 is �to standardize the way machine vendors specify placement rates with specific accuracy requirements for different components�. It also provides a form to record the test results, which include reliability statistics. It was created by individuals with different agendas and is thus a document full of compromises, inconsistencies, and unclear intent. It remains to be seen how the standard will be adopted by the industry.� Said John Pompea, President, Contact Systems
According to IPC, 9850 is in interim final review. http://www.ipc.org/html/status.htm The contacts on this link may be able give you a more direct response about test board CAD data.
