Abstract:
Process for producing an electrical or electronic component with sealed encapsulation comprising:placing, around a support (1) having an electrical or electronic component (5) provided with first electrically conducting tracks (6) radiating towards a periphery of said support, a continuous sealing bead (7) made of at least one metal having a low melting point, at least some of said first electrically conducting tracks (6) stopping short of said bead (7); placing microballs at an end of at least some of the first electrically conducting tracks, said microballs being made of said at least one metal having a low melting point, and having a diameter smaller than a diameter of said bead; positioning, on the support (1) a casing of suitable dimensions, having a main part, said main part having an internal face placeable opposite said support, and provided with hollow conducting elements (3) passing through a thickness of said main part and located vertically above said microballs (8), said casing being provided with second electrically conducting metal tracks (9) extending from an upper end of said hollow conducting elements towards a periphery of said casing, the periphery of said casing resting on said bead (7); positioning and enclosure around said casing and said support; and raising the temperature within the enclosure (10); wherein said at least one metal is melted, said casing (2) is lowered towards the support (1) and hermetically sealed to said support defining an internal volume (4) sealed with respect to the outside and said microballs (8) are soldered to a lower end of the hollow conducting elements (3) in such a way as to ensure that there is electrical continuity between the first electrically conducting tracks (6) and the second electrically conducting tracks.
