  • Fabrication of LTCC T/R modules with multiple cavities and an integrated ceramic ring frame
    Patent number: 7416630
    Abstract: A method of fabricating a transmit/receive (T/R) module utilizing low temperature co-fired ceramic (LTCC) material in place of high temperature co-fired ceramic (HTCC) material and utilizing a combination of multiple lamination steps which also include forming a ceramic frame, as opposed to a metal ring frame, in the process. Brazing metallization is also utilized to attach heat sinks and lids as well as pin connectors. The formation of the pin connectors is provided on the side surface of the T/R module with a side printing process.

  • Method of fabricating structures using low temperature cofired ceramics
    Patent number: 7204900
    Abstract: Disclosed is a method of forming an LTCC structure that involves providing at least a first ceramic tape sheet, laminating at least a second ceramic tape sheet to the at least a first ceramic tape sheet to form a substructure, laminating at least a third ceramic tape sheet to the substructure to form an intermediate structure, and laminating at least a fourth ceramic tape sheet to the intermediate structure to form an LTCC structure.

  • Apparatus and method for side printing on low temperature co-fired ceramic (LTCC) substrates
    Patent number: 7134391
    Abstract: A fixture attached to the rear of the base plate of a semi-automatic screen printer includes an element holder having a vertical recess or pocket for receiving an assembly, such as a substrate, of LTCC laminate material lengthwise therein so as to expose only one side surface to the printing head which would otherwise be prevented because of the height restrictions imposed by the printer head.
