Abstract

The printed-circuit board according to the present invention includes a base member, and a clad metal part that is bonded to one side of the base member, wherein the clad metal part is etched to have an electrical pattern. The vibration motor according to the present invention includes a rotor that includes a printed-circuit board formed with a clad metal part etched to have an electrical pattern, and a stator that includes a brush contacting the clad metal part.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of Korean Patent Application No. 10-2010-0065881 entitled "Printed Circuit Board and Vibration Motor Having the same" filed on July 8, 2010, and adopted References are incorporated in this application in their entirety. technical field [0003] The invention relates to a printed circuit board and a vibration motor with the printed circuit board. Background technique [0004] Recently, as the demand for vibration motors that generate vibrations when mobile information terminals receive calls has increased, vibration motors are being developed day by day. Vibration motors with good mechanical properties, high efficiency and long life have been developed. [0005] However, the commutator portion of the printed circuit board mounted to the rotating portion of the vibration motor is in contact with the brushes, thereby shortening the life of the motor and reducing efficiency due to wea...
