First Claim
Patent Images
1. An electrical device comprising an electrically insulative substrate;
- a thick film heater track applied to the substrate, the thick film heater track comprising a metal and a glass material in composition;
a connection wire for providing an electrical connection to the thick film heater track; and
an electrically conductive adhesive bond for mechanically and electrically connecting the connection wire to the thick film heater track, the adhesive bond comprising a metal and a glass material in composition;
wherein the connection wire comprises a multiplicity of conductive fibres having a diameter in the range of from 10 μ
m to 300 μ
m and arranged to form the connection wire, the connection wire having a deformed end portion to expose the multiplicity of conductive fibres, the end portion of exposed conductive fibres being embedded in the electrically conductive adhesive bond on said thick film heater track so as to provide a mechanical and electrical connection between the connection wire and the thick film heater track.
