Abstract:
An electrical coil module, comprising:a generally flat substrate (21) having an upper surface and a lower surface; a first layout (20) of conducting material constituting a first electrical conductor having an input terminal (23), is arranged on the upper surface of said substrate (21), a second layout (20â€²) of conducting material constituting a second electrical conductor having an output terminal (24), is arranged on the opposite lower surface of said substrate, said first and second conductors are connected by a third electrical connection (22) through the substrate (21), so that an electrical voltage connected between the input and output terminals of the coil module will drive a current from one terminal through the conductor on one side of the substrate via the third connection (22) through the substrate and the conductor on the other side of the substrate to the other terminal.
