Title: PCB transmission line with reduced loss
Inventor: ANDY BECKER
IPC: H05K1/09
Filed: 2017-12-06
Abstract: PROBLEM TO BE SOLVED: To reduce a PCB transmission line loss.SOLUTION: A signal transmission structure in a printed circuit board is formed to reduce a loss, by performing certain adjustment for reducing surface roughness of adjacent power planes, thereby reducing impact of an electromagnetic induction current. This power plane structure also contributes to reduction of a signal transmission loss in the adjacent signal transmission structures, while holding sufficient surface roughness suitable for manufacturing work. Consequently, the transmission structure can transmit a high speed signal more efficiently without causing undesirable attenuation or a loss.SELECTED DRAWING: Figure 5
