摘要:
A dummy circuit pattern is disclosed on a surface of a substrate for a semiconductor package, the dummy circuit pattern including straight line segments having a length controlled so as not to generate stresses within the line segments above a desired stress. The dummy circuit pattern may be formed of lines, or contiguous or spaced polygons, such as hexagons. Portions of the dummy circuit pattern may also be formed with an orientation, size and position that are randomly selected.
