This standard establishes the procedures to characterize the capability of surface mount assembly equipment in specification documents@ as well as in documentation used to verify a specific machine's placement capability conformance to the specification@ while maintaining a placement accuracy to placement speed relationship. Purpose IPC-9850 has been developed to standardize the parameters@ measurement procedures@ and the methodologies used for the specification@ evaluation@ and continuing verification of assembly equipment characterization parameters. These standardized tools shall be used to develop and report the information called out in this standard.
