Abstract:
System of components for hybridisation including a first component (410) with a hybridisation side (411) with first hybridisation studs (414, 414a, 414b), and at least a second component (412) with a hybridisation side (413) with second hybridisation studs (450, 450a, 450b), the first and second hybridisation studs being respectively associated in pairs of studs and arranged in places such that, on the first and second components, each second stud of a pair of studs is located essentially facing the first stud of the pair of studs when the first and second components are assembled with the hybridisation sides facing, one of the first and second studs of at least one pair of studs being equipped with a convex bump (418, 418a, 418b) of meltable material and the other of the aforesaid first and second studs of the pair of studs, called the contact stud (450, 450a, 450b), having a surface made entirely of a material wettable by the meltable material, characterized in that at least one part of the contact stud (450, 450a, 450b) forms a protuberance (452, 452a, 452b) and in that the contact stud has no meltable material before hybridisation.
