The print head and screen assembly of a Semi-Automatic Screen Printer is raised above its normal printing height and selective attachment of several different fixtures on the nest plate for holding the substrate in a desired position during a screen printing operation for printing gold on LTCC substrates.

Ceramic screen printing apparatus

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.

Fabrication of LTCC T/R modules with multiple cavities and an integrated ceramic ring frame

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.

Method of fabricating structures using low temperature cofired ceramics

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.
