Abstract
A high density electrical interconnection device provides a uniform complementary pattern of thieving lines on both X and Y interconnect layers of the high density device to provide for uniform plating of the copper conductors, as well as reducing both nonuniformity and the amount of contraction and expansion of the insulating substrate. The complementary line pattern of thieving lines is generated by computer-aided design techniques and also includes provisions for gaps in thieving lines in one layer so as to eliminate crossover coupling with another layer and provides for visual identification of the thieving lines by the use of an undulating pattern.
