Abstract: With the high integration of electronic products, multi-factor of the electronic components are continuous updating and replacement, the old version of the Integrated Circuits are off production and the embargoes of foreign companies, etc. There are more and more Integrated Circuits of refurbishment, counterfeiting and shoddy, that makes great risks to the reliability of electronic products and military equipments. This paper introduced several methods to identify counterfeit and fake IC in accordance with fake and shoddy IC, from simple to complex, from external to interior, from non-destructive to destructive. By checking the external identification, leads, surface condition and internal technology of the IC, the environmental adaptability test and electrical performance test of the two sieves can be used to judge whether it is a fake and inferior IC effectively.

Key words: integrated circuit, identification, appearance, face-lifting
