This seal ring (1) is made of a clad material in which a base material layer (10) and a brazing filler metal layer (11) arranged on a first surface (10b) of the base material layer are bonded to each other, and a side brazing filler metal portion (11f) of the brazing filler metal layer covering a side surface (10c) of the base material layer is removed.

An electronics housing includes a base body and a metal plating layer formed on a surface of the base body. The base body includes an upper cover, a lower cover and a metal ring. The upper cover and the lower cover are integrally fused by virtue of an ultra high frequency technology, and the metal ring is embedded between the upper cover and the lower cover. A nickel-deposited layer of the metal plating layer is electrolessly deposited on the surface of the base body. A copper layer of the metal plating layer is plated on the nickel-deposited layer. A nano-nickel layer of the metal plating layer is plated on the copper layer. A surface decoration layer of the metal plating layer is plated on the nano-nickel layer. The base body together with the metal plating layer defines at least one assembling hole.

A manufacturing method of an electronic device, that accommodates a gyro element as an electronic component in an inner space formed by a base and a lid as a lid body, includes: preparing the lid in which a groove is provided on the rear surface which is welded with the base, and an opening area of the groove on the inner space side which is greater than an opening area on the outer periphery side of the lid; welding, first, the base and the lid at a portion excluding an unwelded portion that includes at least apart of the groove, of a planned welding portion of the base and the lid; and welding, second, the base and the lid at the unwelded portion such that the groove is closed.

Various embodiments of a sealed package and a method of forming such package are disclosed. The package can include a non-conductive substrate that includes a cavity disposed in a first major surface. A cover layer can be disposed over the cavity and attached to the first major surface of the non-conductive substrate to form a sealed enclosure. The sealed package can also include a feedthrough that includes a via between a recessed surface of the cavity and a second major surface of the substrate, and a conductive material disposed in the via. An external contact can be disposed over the via on the second major surface of the non-conductive substrate, where the external contact is electrically connected to the conductive material disposed in the via. The sealed package can also include an electronic device disposed within the sealed enclosure that is electrically connected to the external contact.

A dielectric header sub-assembly includes a header body with opposed first and second surfaces and a side wall. The first and second surfaces define a header axis extending therebetween. The side wall extends from the first surface to the second surface. The second surface includes a tapered portion. A dielectric header sub-assembly includes a bore. The bore extends from the first surface to the second surface. A first bore opening of the bore proximate to the first surface is greater in area than a second bore opening of the bore proximate the second surface. A method of assembling a header sub-assembly includes inserting an electrical connector into a bore of a header body, applying an active braze filler material into the bore and applying heat to braze the active braze filler material to the header body and the electrical connector.
