CPWG TRANSMISSION LINE AND PCB HAVING THE SAME

摘要

PURPOSE: A CPWG transmission line and a printed circuit board including the same are provided to implement impedance matching by maintaining a CPWG transmission method between the signal lines by forming a dummy solder ball in a ground line of the CPWG transmission line. CONSTITUTION: A ground line(150) is positioned between signal lines(110,120) using a CPWG(Coplanar Waveguide with Ground) transmission method. A solder ball(115,125,151) is formed in each signal line. A metal structure is additionally in the same position as the solder ball. The metal structure is a dummy solder ball or dummy pad.
