Abstract: A package for use in encapsulating an electronic device is disclosed. The package includes a dielectric frame having first and second sides with a pair of apertures extending through the dielectric frame. These apertures are separated by a raised shelf span extending inwardly from an internal perimeter of the dielectric frame. The raised shelf span defines a first thickness of the dielectric frame and a raised sidewall extending outwardly from the second side along an external perimeter of said dielectric frame defines a second thickness of said frame, with the second thickness being greater than the first thickness. Also provided is a metallic component having a flange and a pedestal that extends perpendicularly from the flange. The flange is bonded to the first side of the dielectric frame and extends across one of the pair of apertures with the pedestal extending into that aperture. A gap between the pedestal and the dielectric frame having a width of at least 0.015 inch.

Abstract: A package for use in encapsulating an electronic device is disclosed. In some embodiments, the package includes the following: a dielectric frame having first and second sides, an aperture, a raised shelf portion defined along an internal perimeter of the dielectric frame and extending outwardly from the second side, the raised shelf portion defining a first thickness of the dielectric frame, and a raised sidewall extending outwardly from the second side along an external perimeter of the dielectric frame, the raised sidewall defining a second thickness of the frame, the second thickness being greater than the first thickness; a metallic component bonded to the dielectric frame and extending across the aperture; and a seam weldable, low-profile metallic seal ring bonded to the raised sidewall of the dielectric frame.
