Abstract:
1. A test device for testing an integrated circuit comprising a plurality of contacts, called a test circuit, intended to be tested with the aid of a test printed circuit, called a main circuit, the test device comprising: an insulating, non-conductive membrane of a soft material having two opposite surfaces; two conductive layers each covering a respective one of the two opposite surfaces of said non-conductive membrane; connection means for interconnecting said two conductive layers, said two conductive layers being adapted to come into contact with the test circuit and the main circuit respectively, under the influence of a pressing force exerted during the test between the test circuit and the main circuit deforming the test device; and protrusions arranged on at least one off said two conductive layers according to a predefined pattern as a function of said plurality of contacts of the test circuit, so as to ensure a contact quality between said at least one layer and the test circuit or the main circuit in contact with said at least one layer, under the influence of said pressing force.
