Abstract
An integrated circuit characterization printed circuit board and method is provided for improving the uniformity of impedance introduced by a test fixture across all of the pins of the integrated circuit device. The printed circuit board includes an array of substantially similar test contacts numbering greater than the pins of the integrated circuit device. The array of test contacts includes an active portion configured for electrically coupling with the corresponding pins on the integrated circuit device and an inactive portion adjacent to the active portion and electrically coupled to a reference signal on the printed circuit board.
