  • Publication number: 20130330846
    Abstract: A mechanism to electrically evaluate signals within an encapsulated semiconductor device package without the need for redesigning the package substrate is provided. Test bond pads are provided on a top surface of a semiconductor device die being placed within the semiconductor device package. One or more wire bonds having an elevated loop height are formed on the test bond pads. After encapsulating the semiconductor device package, the package encapsulant is subject to a backgrind process to expose a portion of the test connection wire bonds. Only an amount of the package encapsulant sufficient to expose each test connection wire bond is removed, so that the remaining encapsulant will continue to have the same effect on the package as would be present in a production device. Test probes can then be applied to the exposed test connection wire bonds.
