Position recognition apparatus for printed circuit board, position recognition and processing apparatus, and printed circuit board manufacturing method
Abstract:
There are provided a position recognition apparatus for printed circuit board (PCB), a position recognition and processing apparatus, and a printed circuit board manufacturing method. A position recognition apparatus for PCB configured to recognize a mounting position of an LED package on a PCB, the LED package being including a phosphor emitting fluorescence in operation, includes: an illuminating means configured to irradiate the PCB with light containing a blue component; an observation filter configured to selectively pass at least blue light of reflected light from the PCB and fluorescence from the phosphor and cut light in a wavelength region longer than a wavelength of the blue light; an imaging means configured to capture an image of the light passed by the observation filter; and an image processing means configured to calculate a position of the phosphor on the PCB, based on image data captured by the imaging means.
