METHOD AND APPARATUS FOR VERIFYING A COLOR OF AN LED IN A PRINTED CIRCUIT BOARD

摘要

A method and apparatus for verifying a color of an LED in a printed circuit board include a sensor that permits passage of light from a target wavelengt h of the color and generates a resulting output voltage based upon an intensit y of light of the target wavelength. A test system analyzes the resulting outp ut voltage and provides a pass/fail signal to indicate whether the LED is the correct color and/or in operation.
