Abstract:
1. An apparatus for determining at least one of a presence, an orientation and a color of a component in a printed circuit board, the apparatus comprising: a sensor; a faceplate positioned over the sensor and abutting the component, the faceplate having a window and a thickness that maintains a focal distance of the sensor; a Light Emitting Diode (LED) positioned adjacent to the sensor such that in an illuminated condition, the LED emits light from the window and off the component; an output probe connected to the sensor, the output probe providing an output signal proportional to light reflected from the component, wherein the output probe is spring-loaded to engage the faceplate with the component; and an output device connected with respect to the output probe to indicate a pass-fail condition based on the output signal.
