Abstract:
1. A method for soldering or hybridizing first and second components together using a solder material, wherein at least the first component comprises one or more electrically conducting metal tracks, connected to an equal number of outer connection dots, said method comprising: preparing, on each opposing surface of the components to be welded or hybridized, a wettability surface, said surface prepared on said first component being in electrical contact with said conducting metal track; depositing on one of said wettability suffices an appropriate quantity of solder material, suitable for constituting an inner soldering or hybridization dot between the components; depositing a soldering flux on the outer connection dots and the inner soldering or hybridization dots; contacting the wettability surface of the second component with the solder material thereby deposited; then raising a temperature of a chamber in which the components to be welded or hybridized are positioned, to at least a melting point of the solder material in order to ensure effective soldering or hybridizing of the two components together by a remelt effect, and depositing on said first component and in contact with said conducting metal track, another quantity of said solder material, constituting a sacrificial dot placed in series on said conducting metal track between the outer connection dot and the inner soldering or hybridization dot, said sacrificial dot having a contact area with said first component that is higher than that of said first quantity intended to constitute the inner soldering or hybridization dot.
