Abstract
A method of manufacturing hermetically sealed circuit assemblies (10) having circuit elements (74, 76, 78 and 80) to be compression bonded, a hermetically sealed circuit assembly having circuit elements to be compression bonded and a stack containing at least one hermetically sealed circuit assembly having circuit elements which are compression bonded is disclosed. Uniform thickness of individual hermetically sealed circuit assemblies measured across columns (22-30) is insured by positioning deformable spacers (124-132) in the columns containing the circuit elements to be compression bonded, and deforming the deformable spacers so that a surface of each of the deformed spacers lies within a single plane. Thereafter a compressive force is applied to a stack of one or more circuits through the columns which contain the circuit elements to be compression bonded. The individual hermetically sealed circuit assemblies have circular corrugations (32-40) in a flat surface (14) and circular corrugations (114-122) in a lid (20) which are disposed within the columns containing the individual circuit elements to be compression bonded to permit freedom of motion in all directions of the individ…
