ABSTRACT:
A method to produce a distortion-free asymmetrical low-temperature co-fired ceramic structure comprising at least one layer of glass-containing internal constraining tape and at least one layer of glass-containing primary tape wherein the internal constraining tape and the primary tape are laminated to form an asymmetrical laminate and wherein a release layer is deposited on at least one surface of the laminate forming an assembly, wherein the surface is opposite the position of greatest asymmetry of the laminated layers and wherein the assembly is thermally processed producing a structure exhibiting an interactive suppression of x,y shrinkage.
