The object of this system is to define qu
14、ality 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 detail specifi
15、cation is one of a series of blank detail specifications for 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
