    摘要: An improved rework nozzle includes an open housing which when lowered onto the surface of a board forms a closed cavity. The housing includes venting means which expend air that is input to the cavity, thereby using flow through concepts to maintain a uniform temperature in the cavity. The housing also positioning mechanisms for both aligning a the housing and a captive integrated circuit to a desired footprint on the circuit board, and for limiting movement of the integrated circuit during rework.

    摘要: A nozzle applies fluid (e.g., heated gas) to a solder region of a circuit board component having a set of fluid-delivery edges and a set of fluid-escape edges. The nozzle includes a top member to connect with a fluid source, and a set of fluid-delivery side members coupled to the top member. Each fluid-delivery side member extends from the top member and around a respective fluid-delivery edge of the circuit board component when the circuit board component engages with the nozzle. Each fluid-delivery side member defines (i) at least a portion of a fluid-delivery channel that extends from a vicinity adjacent the top member toward the solder region of the circuit board component when the circuit board component engages with the nozzle, and (ii) a barrier that substantially prevents fluid from escaping from the solder region along the respective fluid-delivery edge for that fluid-delivery side member.

    摘要: The invention is directed to techniques for inspecting a circuit board having a surface that includes at least one circuit board component. The apparatus includes a base, and a set of reflective members that includes at least one reflective member. Each reflective member of the set of reflective members is (i) supported by the base and (ii) movable relative to the base to enable that reflective member to move to an angle that reflects light from a respective portion of a circuit board component (e.g., a solder region between the component and the circuit board) in a direction away from the surface of the circuit board when the base rests on the surface of the circuit board. Since the base can rest on the surface of the circuit board, a technician does not need to hold the apparatus.
