Abstract

Method of hermetically sealing a hole with a fuse material, comprising the following steps: applying a portion of wettable material onto a surface such that it completely surrounds the hole made through said surface and is located outside the hole, or completely surrounds a first part of said surface corresponding to a location of the hole; applying a portion of fuse material on the portion of wettable material and on a second part of said surface located around the portion of wettable material; reflowing the portion of fuse material to form a bump of fuse material which has a shape corresponding to a part of a sphere, which is fastened only to the portion of wettable material and which hermetically plugs the hole; wherein the hole is made in said surface before reflowing the portion of fuse material.
