Abstract
A transitional printed circuit board (10) is disclosed for terminating four multiconductor flat electrial transmission cables (44, 46, 48, 50) wherein only a single substrate (12) is utilized. A first electrical plane (A) is formed on one side of the substrate and a second electrical plane (B) is formed on an opposing side of the substrate with the substrate material in between serving as an insulator. Each electrical plane includes a ground plane (26, 41) and spaced electrical lands (14, 16, 32 ,34). Plated through holes (24) allow the lands from opposing sides to be connected to the opposite side for programmed termination. A series of electrical pads (22, 42) provide for termination to the prongs (52a, 52b) of terminal connector (52). Two cables may be terminated on each electrical plane of the printed circuit board by terminating ground wires of the first cable to the ground plane (26, 41), and the signal wires to the electrical lands (14, 32). The next electrical cable is terminated by connecting signal wires to lands (16, 34). The ground wires of the second cable on each electrical plane are terminated at a bus bar bridge (28, 43) which spans electrical traces (18, 36) which …
