Title: Formation of paired line pattern of printed board
Inventor: KANEKO TADASHI
IPC: H05K3/40
Filed: 1988-07-12
Abstract: PURPOSE:To realize protection from external noises and control of noise emission by disconnecting a first paired line pattern through an interval, by exchanging positions of a signal line pattern and a ground line pattern mutually at a second paired line pattern and by connecting the both patterns respectively. CONSTITUTION:A first paired line pattern 10 which is formed on a first wiring surface 8 of a printed board 4 is disconnected through an interval L. Positions of a signal line pattern 5 and a ground line pattern 6 are exchanged mutually at a second paired line pattern 11 which is formed on a second wiring surface of the printed board with the interval L, and the both patterns are connected respectively. A current which has flown in the direction shown by the arrow C through the signal line pattern 5 flows in the direction shown by the arrow (d) through the signal line pattern 5 whose position is exchanged with that of the ground line pattern 6. A current which has flown in the direction shown by the arrow (e) through the ground line pattern 6 flows in the direction shown by the arrow (f) through the ground line pattern 6 whose position is exchanged with that of the signal pattern 5. Current flows in this way as if the direction reverses at every current-stop interval L. According to this constitution, it becomes possible to control effect of external noises and to reduce emission of noises to the outside.
