Abstract:
An apparatus and a method for polishing a partial section of an optical wave guide of an optical printed circuit board are provided to achieve improved quality of the optical wave guide by sequentially replacing wheels equipped with polishing pads. An apparatus(100) for polishing a partial section of an optical wave guide of an optical printed circuit board includes a motor(110), a wheel(120), a substrate mounting frame(130), a second rotating shaft(140), and a cam(150). The motor rotates a first rotating shaft(112). The wheel has one surface on which a polishing pad(121) is attached and the other surface coupled to a front end of the first rotating shaft. The substrate mounting frame has a surface mounted with an optical printed circuit board having a groove or a hole for exposing the partial section of the optical wave guide. The second rotating shaft is coupled onto the motor such that the second rotating shaft interlocks with the first rotating shaft. The cam is coupled to the second rotating shaft such that the substrate mounting frame horizontally reciprocates on the polishing pad.
