Patent ID: 6973720

Claim:
A method for manufacturing an LED-integrated connector, the LED-integrated connector comprising an elastic connector to be sandwiched and compressed between opposed electrodes of a printed circuit board on which an electric circuit of a chip-type LED is mounted and another circuit board so as to provide an electric connection between the electrodes of the chip-type LED and the other circuit board through the LED-integrated connector, wherein a LED element of the chip-type LED is sealed with resin and mounted on a printed circuit board, and an electrode terminal provided on the printed circuit board extends below the printed circuit board, and the elastic connector is laminated under the printed circuit board below which the electrode terminal extends, the method comprising: (a) providing a liquid polymer containing magnetic staple fibers in a space between a nonmagnetic film and either an electrode on a chip-type LED or an electrode on the printed circuit board, so as to form the elastic connector therebetween; (b) orienting and localizing the magnetic staple fibers in the liquid polymer, included in the elastic connector, with a magnetic field; (c) crosslinking the liquid polymer so that the magnetic staple fibers integrate with the electrodes of the printed circuit board on which the chip-type LED is directly mounted, thereby integrating the bottom surface of the LED-mounted printed circuit board and the elastic connector.
