For interchangea
33、bility at the card level, multiple source availability exists if a card composed of MICS from one source is mechanically and electrically inter- changeable with another card composed of MICS from another source. Numerous aspects need be considered to arrive at the independence of sources; these invo
34、lve production inde- pendence, corporate (or firm) and financial independence, and geographical separation. The production independence of one Bource of another is determined by the extent to which the one source is independent of the other for manufacture; and by the lack of common original supplie
35、rs of raw or processed materials. Design, process information, technol- ogy, and iffusion masks may be derived from a common source. However, in such a case, each device source shail have a demonstrated capability of originating these items. The corporate (or firm) and financial independence of one
36、source of another is determined by Re absence of common directors, common officers, or holders of large common financial interests. Geographical separation is simply the distance between the locations where prin- cipal manufacture takes place by two sources. 6.13 Microelectronic interchangeability D
37、emonstration - interchangeability of microelectronic elements shall be demonstrated as follows: (3) For the interchangeability at the MIC level, it shali be demonstrated for each type of functional MIC from one source, as used in the system, that it is mechanically and electrically interchangeable w
38、ith that from another source (see 6.12). For the interchangeability at the maintenance module level, it shall be demonstrated that modules typical of those to be used in the sys- tem composed of MICS from one source are mechanically and elec- trically interchangeable with modules composed of MICS fr
39、om another source. For the completed equipment, it shall be demonstrated that modules composed of MICS from one source are interchangeable with cor- responding modules cornposed of MICS from another source. When interchange has been effected, no degradation shall take place in system and subsystem p
