13、lankBSQC790303:1994 BSI 10-1999 1 Introduction The IEC Quality Assessment System for Electronic Components is operated in accordance with the statutes of the IEC and under the authority of the IEC. The object of this system is to define quality assessment procedures in such a manner that electronic

14、components released by one participating country as conforming with the requirements of an applicable specification are equally acceptable in all other participating countries without the need for further testing. This blank detail specification is one of a series of blank detail specifications for

15、semiconductor devices and shall be used with the following IEC publications: 747-10/QC700000, Semiconductor devices Discrete devices and integrated circuits Part10: Generic specification for discrete devices and integrated circuits. 748-11/QC790100, Semiconductor devices Integrated circuits Part11:
