Abstract
Abstract A sealing frame arrangement is disclosed for creating a hermetic seal between two components or bodies such as a connector and heat sink module of an integrated circuit package. The frame members are configured to fit together along facing surfaces and to be joined to the two bodies along the inner edge of their outside (non-facing) surfaces. The sealing arrangement is completed by a third seal formed along the outer facing edge of the frames. The frames extend a sufficient distance beyond the two components to permit severing the frames inside the third seal and resealing. Preferably, the frames are of sufficient width to provide a multiplicity of sealing regions so that the third seal can be broken and resealed a number of times. The seal frames may be of stepped or corrugated configuration in which the individual seals are formed along the mating steps.

Claim 1
Independent Claim
200 words
A sealed assembly, comprising: (a) a first body having a surface; (b) a second body having a surface for mating with the first body surface; (c) a sealing frame arrangement for sealing the first body surface to the mating second body surface, comprising first and second frames having outer surfaces of configuration matched to the configuration of, respectively, the first and second body surfaces, and having mating facing inner surfaces; said first frame being sealed to the first body surface at a first location defined along the outer surface of said first frame; the second frame being sealed to the second body surface at a second location defined along the outer surface thereof of said second frame; and the first and second frames being sealed at a third location defined along the facing inner surfaces thereof; said frames extending outside the first and second body surfaces such that the third seal is spaced from the first and second body surfaces thereby defining a first space for severing said frames inside the third seal and for resealing the frame inside said severed location; and wherein the frames are of stepped configuration and the third seal is formed in mating steps thereof.
Claim 2
Dependent Claim
200 words
A sealed assembly, comprising: (a) a first body having a surface; (b) a second body having a surface for mating with the first body surface; (c) a sealing frame arrangement for sealing the first body surface to the mating second body surface, comprising first and second frames having outer surfaces of configuration matched to the configuration of, respectively, the first and second body surfaces, and having mating facing inner surfaces; said first frame being sealed to the first body surface at a first location defined along the outer surface of said first frame; the second frame being sealed to the second body surface at a second location defined along the outer surface thereof of said second frame; and the first and second frames being sealed at a third location defined along the facing inner surfaces thereof; said frames extending outside the first and second body surfaces such that the third seal is spaced from the first and second body surfaces thereby defining a first space for severing said frames inside the third seal and for resealing the frame inside said severed location; and wherein the frames are of stepped configuration and the third seal is formed in mating steps thereof.
Claim 3
Dependent Claim

A sealed assembly, comprising: (a) a first body having a surface; (b) a second body having a surface for mating with the first body surface; (c) a sealing frame arrangement for sealing the first body surface to the mating second body surface, comprising first and second frames having outer surfaces of configuration matched to the configuration, of, respectively, the first and second body surfaces, and having mating facing inner surfaces; said first frame being sealed to the first body surface at a first location defined along the outer surface of said first frame; the second frame being sealed to the second body surface at a second location defined along the outer surface thereof of said second frame; and the first and second frames being sealed at a third location defined along the facing inner surfaces thereof; said frames extending outside the first and second body surfaces such that the third seal is spaced from the first and second body surfaces thereby defining a first space for severing said frames inside the third seal and for resealing the frames inside said severed location, said frames further comprising space inside the resealing space for severing and resealing the frames at least a second time; and wherein the frames are of stepped configuration and the third seal is formed in mating steps thereof.
Claim 4
Dependent Claim
220 words
A sealed assembly, comprising: (a) a first body having a surface; (b) a second body having a surface for mating with the first body surface; (c) a sealing frame arrangement for sealing the first body surface to the mating second body surface, comprising first and second frames having outer surfaces of configuration matched to the configuration, of, respectively, the first and second body surfaces, and having mating facing inner surfaces; said first frame being sealed to the first body surface at a first location defined along the outer surface of said first frame; the second frame being sealed to the second body surface at a second location defined along the outer surface thereof of said second frame; and the first and second frames being sealed at a third location defined along the facing inner surfaces thereof; said frames extending outside the first and second body surfaces such that the third seal is spaced from the first and second body surfaces thereby defining a first space for severing said frames inside the third seal and for resealing the frames inside said severed location, said frames further comprising space inside the resealing space for severing and resealing the frames at least a second time; and wherein the frames are of stepped configuration and the third seal is formed in mating steps thereof.
