Patent ID: 7944028

Claim:
A set of at least two contacts, for connecting a first electronic device having a generally flat surface, a BGA or a chip, to a second electronic device having a generally flat surface and being generally parallel to said first device, a PCB or a substrate, both devices having corresponding contact pads, each contact being made out of a resilient electrically conductive material, such as copper, and comprising a tall, slim and slender column-like body, and a first end and a second end, said first end being capable of being attached to a BGA contact pad, and being referred to as the Contact BGA End, and said second end being capable of being attached to the PCB contact pad, and being referred to as the Contact PCB End, the column portions of the contacts being arranged to be generally perpendicular to the generally flat surface of the BGA and to the generally flat surface of the PCB, wherein the column portions of the contacts have a generally elongated cross-section, having a relatively small thickness compared to the width of the cross-section, and wherein the column portions of each one of said contacts is arranged to be oriented so that the contact would present the least resistance to bending in the general direction of the expected thermal deformation of the assembly of BGA and PCB, at the location of the respective contact.
