ABSTRACT:
An apparatus and method for assembling electrical connector components, including headers, connectors, and terminals, to circuit bearing substrates functions to align the terminal pins of a connector or header into a preferred position and install an annular solder preform onto each terminal pin. The pin alignment apparatus includes movable jaw plates the define a variable size aperture for encompassing each of a plurality of terminal pins, including terminal pins that are bent or skewed relative to an intended position. A carrier plate overlies the jaw plates and includes a plurality of cavities for receiving solder preforms to be installed over each of the terminal pins. The jaw plates are positioned over the terminal pins and moved to a closed position to align all the terminal pins, including any bent or skewed terminal pins, to an intended alignment. The pin alignment apparatus is advanced along the pins until the solder preforms are positioned adjacent the lower portions of the terminal pins at which time the jaw plates are repositioned to release the solder preforms. The present invention advantageously provides for the rapid alignment of the terminal pins of a header or connector and the reliable and efficient installation of solder preforms in such a way that deposition of solder on the contact zones of the terminal pins is minimized.
