Abstract
The invention is an electrical component with a body element comprising an organic substrate portion and a laser formed, resistor portion carburized thereon. A first electrical conductor is electrically connected to one location on the resistor portion so as to form one terminal for connection to an electrical circuit and a second electrical conductor is electrically connected to the resistor portion at a different location so as to form another terminal for connection to the electrical circuit.
Claims22
An electrical component comprising:
- an insulator substrate portion of a homogeneous organic body element and a carburized conductive resistor portion means formed from said homogeneous organic body element;
- a first electrical conductor electrically connected to one location on said resistor portion means so as to form one terminal for connection to an electrical circuit;
- and
- a second electrical conductor electrically connected to said resistor portion means at a different location spaced from said one location so as to form another terminal for connection to an electrical circuit.
1 more element
A method of making electrical components comprising the steps of:
- forming a homogeneous organic substrate;
- applying heat so as to carburize only a predetermined conductive resistor portion of said substrate and leave an insulator substrate portion thereof;
- attaching a first electrical conductor to one location on said resistor portion;
- and
