ABSTRACT:
A support for integrated circuit chips to be mounted on an interconnecting base provided with conductive areas. The support consists of a flexible strip made of an inextensible insulating material having equidistant openings towards the center of each of which extend overhanging interface conductors electrically independent of each other. The free inner ends of the conductors in each opening correspond to that of the contact areas on a chip placed at the center of the opening, and each of the conductors has at a point along its overhanging portion, a contact region which is intended to be soldered to a corresponding conductive area on the said interconnecting base. The overhanging portion of each interface conductor is composed of a main part of constant width which terminates, near the free inner end of the said conductor, in a straight terminal part two or three times narrower than the main part, and which is shaped so as to have, between its contact region and the portion of it which is attached to the support, an open-centered structure whose sides have a width substantially equal to half the width of the said main part.
