• JEDEC

The JEDEC Solid State Technology Association (Once known as the Joint Electron Device Engineering Council) Is the semiconductor engineering standardisation body of the Electronic Industries Alliance (EIA), a trade association that represents all areas of the electronics industry. JEDEC was originally created in 1960 as a joint activity between EIA an NEMA, to cover the standardisation of discrete semiconductor devices and late expanded in 1970 to include integrated circuits. JEDEC does its work through its 48 committees/ subcommittees that are overseen by the JEDEC Board of Directors. Presently there are about 300 member companies in JEDEC including both manufacturers and users of semiconductor components and others allied to the field. JEDEC develops standards through its 48 Committees/Subcommittees overseen by the JEDEC Solid State Technology Association Board of Directors. About 300 member companies representing every segment of the industry actively participate on these committees to develop standards to meet the industry and user needs. Committees where ST maintains a recent active participation: JC-11 Committee: Mechanical (Package Outlines) Standardisation JC-14.1 Subcommittee: Reliability Test Methods for Packaged Devices.
