JC-11 is responsible for the creation and update of the registered and standard outlines in JEDEC Publication 95.

The committee and its subcommittees generate design guidelines, standardized measuring methods for mechanical features, and standard- or registration-type mechanical outlines for microelectronic packages and assemblies, corresponding socket outlines, mechanical, environmental and ergonomic performance specifications, footprints and land patterns, and development of designators for semiconductor device packages. To accomplish these functions, the committee provides technical support and design recommendations to establish and define parameters that ensure mechanical interchangeability of parts.
