This Sectional Specification relates to the sockets for chip carriers of assessed quality. The purpose of this Specification is to provide a means of assuring interchangeability between devices and compatibility between the board and the chip carrier and to provide standard socket test methods, gauges and performance requirements.

Object The object of this Specification is to define:

A unified numbering system to be used for chip carrier sockets standardized by the Electronic Industries Association (EIA) .

Functional levels and standard test methods and gauges for use in the examination of these sockets.

Appropriate reference dimensions of the mating devices and board layout to establish intermateability and interchangeability criteria.

Test severities and performance requirements prescribed in Detail Specifications referring to the Sectional Specification shall be equal to or greater than those specified herein: degradations are not permitted .
