Method for producing a tube
First Claim
1. A method for producing a tube comprising:
- rolling a green ceramic sheet around a form for more than one revolution, the green ceramic sheet having a first surface and an opposed second surface and at least one electrical conductor disposed on each of the first and second surfaces, the second surface facing the form, wherein said rolling causes at least one electrical conductor on the first surface to contact at least one electrical conductor on the opposed second surface;
restraining the rolled green ceramic sheet on the form;
applying a lamination pressure to set the green ceramic sheet on the form; and
,firing the rolled green ceramic sheet.

Abstract
A method is described for producing tubular substrates having parallel spaced concentric rings of electrical conductors that can be used as the drift tube of an Ion Mobility Spectrometer (IMS). The invention comprises providing electrodes on the inside of a tube that are electrically connected to the outside of the tube through conductors that extend between adjacent plies of substrate that are combined to form the tube. Tubular substrates are formed from flexible polymeric printed wiring board materials, ceramic materials and material compositions of glass and ceramic, commonly known as Low Temperature Co-Fired Ceramic (LTCC). The adjacent plies are sealed together around the electrode.
