Abstract:
Embodiments of the invention include a tool and method for automatically replacing defective pogo pins for use in testing a semiconductor package. Aspects of the invention include a nozzle tip and a pin management valve assembly coupled to the nozzle tip. The pin management valve assembly is actuatable to couple an open pin management valve or a partially closed pin management valve to the nozzle tip. The open pin management valve includes a first diameter and the partially closed pin management valve includes a second diameter. A vacuum reservoir is coupled to the pin management valve assembly and a vacuum management valve is positioned between the pin management valve assembly and the vacuum reservoir. The vacuum management valve is actuatable between an open and closed position.
