This specification provides the engineering and performance requirements for a family of high density blade-and-tuning fork contact printed wiring board (PWB) connectors of assessed quality designed for use in electronic and electrical equipment. It shall be used in conjunction with the basic specification EIA-3 64 Electrical Connector Test Procedures@ which documents test procedures and test sequences. These connectors are not intended for applications at frequencies exceeding 3 MHz@ except in applications such as high speed digital logic. The special requirements and tests for these high speed applications and other required test procedures not provided in EIA-364 are specified in 4 of this specification. Both the male (module) connectors and the mating female (backplane) connector are included in this specification.
