Abstract:
1. Process for making an electrical connection between a first component comprising a set of first pads and a set of hard conducting tips on one face, and a second component comprising a set of second pads and a set of ductile conducting bumps on the other face, in which the two faces are made to face each other and they are brought towards each other such that the tips can penetrate into these bumps, wherein a space between two tips is less than a width of a particular bump and less than a width of a first pad and wherein each tip has an angle of less than 30° at its vertex, and wherein there is a ratio of more than ten between a Young's modulus value of each tip and each bump, the first pads each having a first side and a second side, wherein the tips on at least one of the first pads are equally spaced with respect to one another across the first face from the first side to the second side.
