Abstract:
Systems, manufactures, methods and/or techniques for a merged fiducial for chip packages are described. According to some embodiments, an integrated circuit package may include a package substrate having a first side and a second side, a plurality of conductive traces coupled to the first side and a plurality of balls disposed on the second side. The balls may be adapted to electrically connect the laminate package to a circuit board. The integrated circuit package may include a plurality of ball pads disposed on the second side, the ball pads being adapted to electrically connect the plurality of balls to the plurality of conductive traces. One or more of the ball pads may be uniquely shaped when compared to the rest of the plurality of ball pads, optionally, to serve as a fiducial to designate an A1 pin or ball of the laminate package.
