    摘要: An integrated circuit system comprising a first integrated and at least one of a second integrated circuit, interposer or printed circuit board. The first integrated circuit further comprising a wiring stack, bond pads electrically connected to the wiring stack, and bump balls formed on the bond pads. First portions of the wiring stack and the bond pads form a functional circuit, and second portions of the wiring stack and the bond pads form a test circuit. A portion of the bump balls comprising dummy bump balls. The dummy bump balls electrically connected to the second portions of the wiring stack and the bond pads. The at least one of the second integrated circuit, interposer orprinted circuit board forming a portion of the test circuit.
