Abstract
A packaged electrical component includes a tubular body having first and second ends and an opening at the first end for receiving an electrical component; an electrical component disposed within the tubular body; an end cap mounted on the first end of the tubular body, closing the opening; and a fluid-filled pressure-applying element disposed within the tubular body between the end cap and the electrical component, applying pressure to the electrical component within the tubular body. The fluid-filled pressure-applying element is preferably a variable volume container that contains a gas, a liquid, or a solid produced by curing of a liquid. A fluid is injected into the container after assembly of the package so that a uniform pressure is applied to the component compensating for thickness non-uniformities of the component. Assembly is simplified since the element is pressurized after assembly of the package rather than while the package is being manufactured.
