Adapter frame for testing printed circuits of high density

Abstract

Abstract The invention relates to an adaptor frame for bare printed circuits. This adaptor frame is used to make an electrical connection intended to test the electrical continuity and insulation of the chips and of the conducting tracks of the printed circuit. This adaptor frame comprises two faces, one supporting contacts (12) at the same pitch as the contact surfaces of the printed circuit element to be tested, and the other supporting chips (14) at the same pitch as the points of the probe tester (1) on which the pitch adaptor (8) rests. The face supporting the contacts, at the same pitch as that of the printed circuit to be tested, possesses a radiused part (18) which, when a pressure force is exerted on the printed circuit to be tested, and by virtue of the flexibility and elasticity of the material used to make this pitch adaptor, ensures the electrical connection between the points situated at a pitch of 2.54 mm and the contact surfaces of the bare printed circuit element. <IMAGE>
