Abstract (en)

[origin: FR2890067A1] The method involves producing wettability areas (10, 11) on opposing faces of protective cover and electronic components, where one area has a layer of gold and a surface area (S2) greater than a surface area (S1) of the other area. A quantity of sealing material comprising indium is deposited on one of the areas by evaporation. The wettability area (11) is brought into contact with the deposited material. Temperature of a chamber containing the elements is raised to 250 degree Celsius in a non-oxidizing atmosphere, in order to seal the cover and the components to one another by remelting.
