Patent ID: 7536909

Claim:
A method of manufacturing a device for providing tri-axial measurements in an x-direction, a y-direction, and a z-direction, the method comprising the steps of: providing a leadframe, a plurality of input/output leads, and a plurality of z-axis sensor leads; attaching at least one X- and Y-axis sensor die, having orthogonal sensing directions, and at least one integrated circuit to be in at least one of physical communication and operational communication with the leadframe, the plurality of input/output leads, and the plurality of z-axis sensor leads; attaching a z-axis sensor die, having a sensing direction, to at least two of the plurality of input/output leads and to at least two of the plurality of Z-axis sensor leads so that the sensing direction of said Z-axis sensor die is in the same or substantially the same plane as the orthogonal sensing directions of the at least one X- and Y-axis sensor die; pre-encapsulating the Z-axis sensor die, some portion of the plurality of input/output leads, and some portion of the plurality of Z-axis sensor leads; and re-positioning the pre-encapsulated Z-axis sensor die so that its sensing direction is orthogonal or substantially orthogonal to the orthogonal sensing directions of the at least one X- and Y-axis sensor die; and encapsulating the leadframe, the plurality of input/output leads, the plurality of Z-axis sensor leads, the at least one X- and Y-axis sensor die, the at least one integrated circuit, and the pre-encapsulated Z-axis sensor die in a final molding.
