Abstract
An electrical contact having transmission-coil sections with at least two tightly wound turns. Active-coil sections are integral with, and positioned between the transmission-coil sections so as to provide electrical signal communication between the two transmission-coil sections, and spring characteristics. The transmission-coil sections are over coated with a conductive noble metal so as to fuse each of the tightly wound turns together to thereby provide for a shortened electrical transmission pathway through the electrical contact. An LGA interposer for providing data communication between a first and a second array of contact pads is also provided having a dielectric housing with an array of cavities; and a plurality of electrical contacts positioned within the cavities.
