CA 2428690

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 wavelength of the color and generates a resulting output voltage based upon an intensity of light of the target wavelength. A test system analyzes the resulting output voltage and provides a pass/fail signal to indicate whether the LED is the correct color and/or in operation.

L'invention concerne un procédé et un appareil destinés à identifier la couleur d'une diode électroluminescente dans une carte de circuit imprimé qui comprend un détecteur permettant le passage de la lumière à partir d'une longueur d'onde cible de la couleur et générant une tension de sortie résultante basée sur une intensité de lumière de la longueur d'onde cible. Un système d'essai analyse la tension de sortie résultante et génère un signal de défaillance/réussite indiquant si la diode électroluminescente est de la bonne couleur et/ou en fonctionnement.
