Abstract
A flexible electric circuit, for example an electric heater, comprises a metallised fabric (14) the metal of which is photochemically etched to form the circuit (16), the fabric preferably being porous.
Claims10
A flexible electric circuit comprising a metallised substrate of porous fabric having a plurality of components each encapsulated with metal, wherein the metal on the metallised substrate of fabric is photochemically etched to form the circuit by selectively etching out metal encapsulated about the plurality of components of the substrate of porous metallised fabric.
A method of manufacturing a flexible circuit comprising the steps of:
- providing a substrate of porous metallised fabric having a plurality of components each encapsulated with metal;
- and
- photochemically etching the metal encapsulated about the components of the substrate of porous metallised fabric to form the circuit by selectively etching out the metal encapsulated about the components of the substrate of porous metallised fabric.
