Abstract:
1. An interconnection device, referred to as a probe, adapted for mechanically and electrically engaging a first electrical or electronic device, a chip or IC Package or substrate, referred to generically as the first device, a) said first device having a generally flat surface and at least a first and a second active contact element, pads, bumps or balls, referred to as first device pads, b) said first device pads being arranged in a certain pattern, referred to as the first device pad pattern, c) having a certain distance between the center of said first device first pad and the center of said first device second pad, said distance referred to as the first device pad pitch, d) said probe having at least a first and a second contact element, referred to as springs, e) each of said springs having a generally elongated slender curvilinear body, f) said spring body having a spring middle portion, and a spring first end portion ending with a spring first tip, which in turn is ending with a spring first contact point, g) each of said first and second spring being fixedly mounted at about its spring middle portion, on or in a first carrier, at a fixation spot in said first carrier, said spring first end portion exiting from said fixation spot of said first carrier at a point facing towards the first spring tip, said point being referred to as the spring first anchor point, h) said first carrier together with said number of springs mounted on or in it being referred to as a first carrying module; and i) said probe having a second module similar to said first module, disposed adjacent to said first module, said second module carrying a number of springs, similar to said first and second springs, j) said probe having also a first guide, referred to as the first comb, located generally adjacent and parallel to said first device, k) said first comb having at least a first and a second first comb aperture, l) said first comb apertures being arranged in a certain pattern, referred to as the first comb apertures pattern, m) having a certain distance between the center of said first aperture and the center of said second aperture of said first comb, said distance referred to as the first comb apertures pitch, n) said first comb apertures pattern corresponding to said first device pad pattern, o) said first comb apertures pitch corresponding to said first device pad pitch; p) said probe having also a housing, q) said housing having means to contain said first and second modules and said first comb, and to fixate them all in certain positions relative to each other and to said first device, r) each one of said spring first tip of said first and second spring passing through a corresponding aperture of said first comb, referred to as the spring first aperture, and said first contact points of said first and second springs protruding beyond the first comb, the amount of protrusion being large enough to allow the spring contact points to touch and make contact with their corresponding pads of said first device, s) each one of said first and second springs being arranged so as to have an interaction between its spring body and said first device, so as to create a normal force between its first contact point and its corresponding pad of said first device, in a direction generally perpendicular to the general surface of said first device; t) wherein
