Abstract
An interposer for a land grid array includes a dielectric grid having an array of holes and a resilient, conductive button disposed in one or more of the holes. The button includes an insulating core, a conducting element wound around the insulating core, and an outer shell surrounding the conducting element. The characteristics of the conducting element and the buttons may be chosen such that the contact force and resistance, and compressibility or relaxability of the conductive buttons can be selected within wide limits. Contact areas between the shell and the conducting element urge a substantially corresponding displacement in both the conducting element and the shell when the button is under compression or relaxation. The interposer alternatively can include an insulating sheet and rather than conductive buttons contain conducting elements disposed therein having contact areas with the block. The interposer when positioned between a land grid array and an electrical circuit component can accommodate relatively large nonplanarity between respective mating surfaces of the two interconnected components while establishing and maintaining contact between each conducting element and…
