Patent ID: 7695663

Claim:
A method of making a hermetic terminal assembly at room temperature comprising the steps of: inserting at least one of the group consisting of a temporary stop, a shim, a jig, or a combination thereof, on the bottom face of a terminal assembly thereby blocking assembly core open passageways, mounting the terminal assembly inside a vacuum chamber using a temporary assembly perimeter seal and flange or threaded assembly interfaces, mixing a seal admixture and hardener in a mixer conveyor to form a polymer seal material, conveying the polymer seal material into a polymer reservoir, feeding the polymer seal material from the reservoir through a polymer outlet valve and at least one polymer outlet tube into the terminal assembly core thereby filling interstitial spaces in the core adjacent to service conduits, temporary stop, and a terminal assembly casing, drying the polymer seal material at room temperature thereby hermetically sealing the core of the terminal assembly, removing the terminal assembly from the vacuum chamber, and removing the temporary stop, shim, jig, or combination thereof, wherein said seal admixture comprises a mixture of at least one polymer and at least one material selected from the group consisting of graphite fibers, ceramic powder, glass powder, and glass fibers, and at least one of the service conduits is configured with at least one of the group consisting of a taper and a bend for transferring a shear stress generated by a pressure difference across the polymer seal material into compression stress on the polymer seal material, wherein at least one of said service conduits passes from one side of said polymer seal material to another and wherein said hermetic terminal assembly is an electronic inverter/converter terminal assembly.
