Patent ID: 7524704

Claim:
A method for encapsulating a component, especially an electric or electronic component, comprising: firstly using a chamber in which there is a vacuum or controlled atmosphere; then positioning a continuous sealing seam made of a metal or a metal alloy that advantageously has a low melting temperature on a wettable surface previously placed on a substrate comprising at least one component and extending around the periphery of the component, positioning a package or cover of appropriate dimensions on the sealing seam; and finally raising the temperature inside said chamber in order to achieve fusion of the material that constitutes the sealing seam, thereby causing firstly the cover or package to drop onto the substrate and consequently and secondly leaktight, hermetic sealing of the cover or package on said substrate capable of providing leaktight isolation of an internal cavity thus defined from the external atmosphere; wherein the wettable surface placed on the substrate around the periphery of the component and on which the sealing seam is positioned has intervals of constrictions in one direction of a plane parallel to an upper surface of the substrate other than in the direction parallel to the main direction in which the sealing seam extends.
