Abstract

This is a method of producing printed circuits in which the individual conductors or otherwise electrically active films are deposited on a fabric of quartz, glass or similar materials or on individual threads of such substances. These are subsequently combined into fabrics.

Producing Printed Circuits

This is a method of producing printed circuits in which the individual conductors or otherwise electrically active films are deposited on a fabric of quartz, glass or similar materials or on individual threads of such substances. These are subsequently combined into fabrics.

The fabric comprises, for example, quartz warp threads 15 and woof threads 16 and 17. Woof threads 16 and 17 have a conductive gold coating. They are arranged to contact alternately two gold coated conductive warp threads 20. If desired, insulating woof threads can be included between threads 16 and 17.

An electroluminescent substance 19 is pressed into a portion of the fabric between warp threads 20. When a potential is applied to the two threads 20, an electric field is produced between the threads 16 and 17 which causes the electroluminescent film 19 to luminesce.
