The object of this system i
21、s to define quality assessment procedures in such a manner that electronic 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
22、detail specification is one of a series of blank detail specifications for semiconductor devices and shall be used with the following publications: IEC 747-10/QC 700000, Semiconductor devices Discrete devices and integrated circuits Part10:Generic specification for discrete devices and integrated ci
