Abstract: Collagen casings having a final moisture content of between about 18.5% to 21.5% by weight may be produced by controlling the drying process for a collagen casing ready for drying. The collagen casing is treated with a suspension of polysorbate in vegetable oil following the drying process. The resulting collagen casing does not require treatment in a humidification chamber to increase the moisture content of the casing prior to shirring.

Abstract: Conformal-coated devices packaged to be compatible with automated handling equipment. In one arrangement, open-sided, injection-molded shells are mounted around conformal-coated devices to provide dimensionally stable packaging that is compatible with device carriers and automated packaging tool heads that are indexed to select and place the devices. In another arrangement, the coating is heated and additional material is added and re-flowed to define unique surface regions compatible with automated handling equipment.

Abstract: Discrete circuit devices constructed on a component substrate thermally matched to the supporting substrate of a higher level circuit assembly. Upon securing each component to the supporting substrate of a higher level circuit assembly, a connection subject to reduced thermal stress is obtained. In the construction of an exemplary surface mount, hybrid component containing resistors and capacitors, a component substrate of a polyimide impregnated material is populated with a repeating matrix of chip capacitors and chip resistors, which are adhesively bound and soldered to selected termination pads containing high temperature solder filled through vias. The substrate is epoxy encapsulated and then diced at selected ones of the through vias into multiple components. Each thermally matched component is resoldered at the separated vias to obtain surface mount terminations. Portions of the vias may be exposed through the component sidewall to permit circuit test.
