Counterfeit Detection

The History:

Prior to the COTs directive, the Defense Supply Center Columbus (DSCC) required hermetically sealed ceramic or metal packaged semiconductors to be qualified only for the defense industry. All parts used in defense and space contracts were required to be qualified to a “mil-spec” and the manufactures were controlled and audited by the agency periodically with traceability throughout life cycle of the product. In June 1994, Defense Secretary William Perry, under President Clinton, signed a directive ordering the armed forces to buy products and components to the extent possible from Commercial off-the-shelf (COTS) sources rather than from defense contractors, signaling a major departure from the traditional "mil-spec" system of over 30,000 military specifications and standards. Although the intent was to save cost and progressively improve the defense industry, the Perry directive initiated the elimination of DSCC QPL (Qualified Product List) for semiconductor components and led the way for the incorporation of COTS in defense contracts. The high reliability semiconductor industry lost parts traceability for testing, certification, source control and pedigree for the aerospace, military and space industry supply system.”
