Abstract
A flexible printed circuit board module includes a flexible printed circuit board having a conductive layer in an upper part of the flexible printed circuit board, an optical fiber disposed under the flexible printed circuit board, light propagating through an interior of the optical fiber and a supporting member supporting an optical fiber and having a first reflecting member reflecting incident light from the flexible printed circuit board so as to connect the light to the optical fiber.
Claims20
A flexible printed circuit board module comprising:
- a flexible printed circuit board having a conductive layer in an upper part of the flexible printed circuit board;
- an optical fiber disposed under the flexible printed circuit board, wherein light propagates through an interior of the optical fiber;
- and
- a supporting member supporting the optical fiber and having a first reflecting member reflecting incident light from the flexible printed circuit board so as to guide the light to the optical fiber.
A method for fabricating a flexible PCB supporting member comprising:
- cutting a first groove from a first end to a second end of said supporting member, said first groove having a first surface extend substantially at a 45 degree angle along said direction of said first groove;
- and
- cutting at least one second groove substantially perpendicular to said first groove, each of said at least one second groove extending from said first groove to a third end of said support member, wherein said first surface extends away from said third surface.
A flexible PCB assembly comprising:
- a light source and a light detector formed on a first surface of a conductive plate, said conductive plate having openings therein to allow light to pass therethrough;
- a supporting assembly comprising first and second jig members attached to a second surface of a conductive plate, said supporting assembly comprising:
- a first joining assembly and a second joining assembly, each including a first groove traversing said assembly and at least one second groove extending substantially perpendicular from said first groove, said first groove having at least one surface extending at substantially a 45 degree angle in the direction of said first groove, wherein said first joining assembly is position to receive a light from said light source and said second joining assembly is positioned to provide a light to said light detector;
- and
- an optical fiber positioned in respective ones of said at least one second groove and extending between said first joining assembly and said second joining assembly, wherein light from said light source is directed toward one end of said optical fiber via said 45 degree angle surface in said first joining assembly and light exiting a second end of said optical fiber is directed toward said light detector via said 45 degree angle surface in said second joining assembly.
