ABSTRACT:
A device and method for configuring the leads of a light-emitting diode into a desired configuration and testing the polarity of the light-emitting diode before it is mounted to a printed circuit board. In one embodiment, the device has a non-conductive base that has a top surface with a first deformation point defining a location about which a hot lead is desirably deformed and a second deformation point defining a second location about which a ground lead is desirably deformed. The configuring and testing device also has a guide structure on the top surface of the base member, a first peg connected to the base member at the first deformation point, a first conductive contact element positioned to engage the hot lead, a second peg connected to the base member at the second deformation point, and a second conductive contact element positioned to engage the ground lead. The first conductive contact element is coupled to a positive terminal of a power supply, and the second conductive contact element is coupled to a ground terminal of a power supply. In operation, the guide structure retains the light-emitting diode element in a test, and configuration position such that the hot and ground leads are positioned adjacent to the first conductive contact element and the second conductive contact element, respectively. The polarity of the light-emitting diode is tested by energizing the first conductive contact element, and if the polarity of the light-emitting display is correct, the leads are then deformed about the first and second pegs to configure the leads into a desired configuration.
