PRINTED CIRCUIT BOARD INCLUDING AT LEAST ONE LAYER

摘要

PURPOSE: A PCB(Printed Circuit Board) which includes one or more layers is provided to improve yield by reducing the whole thickness. CONSTITUTION: A second layer(200) is arranged at the upper side of a first layer. The first layer comprises a first signal line, a first ground line, and a second ground line. The first signal line transfers a signal. The first ground line and the second ground line are formed at both sides of the first signal line while having a first interval. The second signal line transfers the signal. The second layer comprises a second signal line, a third ground line, and a fourth ground line. The third ground line and the fourth ground line are formed at both sides of the second signal line while having the first interval.
