Abstract
In summary, the present invention is a flexible printed circuit that eliminates the need for lead wire routing. The flexible printed circuit of the present invention comprises a plurality of electrical paths surrounded by a sheath of pliable MYLAR (polyester film) plastic. One side of the plastic is an adhesive that holds the circuit in place after it is wrapped around the shaft of the motor. On the other side, the mylar sheath opens to expose the ends of each electrical path. Small amounts of solder are pre-deposited at these exposed ends. A probe, suitably heated and applied to these ends, releases the solder to form a electrical and physical contact.
