Patent ID: 8890071

Claim:
A method for assembling and hermetically sealing a package consisting of a side wall mounted on, or integral with, a substrate, with the space thus defined accommodating at least one component that operates in an environment of one of a vacuum, reduced pressure and a controlled atmosphere, said space being closed off by a hermetic sealing cover sealed on said side wall, with this method comprising: depositing a metallic connector element, also referred to as a brazing preform, onto the upper face of side wall; depositing the upper cover on, and in contact with, said brazing preform; subjecting the assembly thus obtained to the desired environment in terms of a kind of gas and operating pressure of the component; increasing the temperature to a value that is at least in excess of the melting temperature of the material that constitutes the brazing preform; then lowering said temperature in order to cause solidification of said brazing material and, consequently, sealing of the cover on the side wall, wherein at least one recess is provided in the side wall capable of accommodating a functional element mounted so that said functional element overhangs said at least one recess, said functional element being shaped accordingly; and then, after fitting said functional element, the brazing preform is deposited and then the cover is also deposited in said recess, thereby causing cooperation of said functional element with the preform and, consequently, positioning said functional element in accordance with its operating mode.
