Abstract
A circuit board includes a first section on a left side of a third section in a signal-conductor-layer left-right direction and extending in parallel or substantially in parallel with the third section in a signal-conductor-layer front-back direction when viewed in a stacking direction. The first section includes first thin line portions and first thick line portions, each of the first thick line portions has a line width greater than a line width of each of the first thin line portions. The first thin line portions and the first thick line portions are alternately arranged in the signal-conductor-layer front-back direction. In the signal-conductor-layer left-right direction, center lines of the first thin line portions are positioned leftward relative to center lines of the first thick line portions.
Claims19
A circuit board comprising:
- a board body including a plurality of insulator layers that are stacked;
- a first signal conductor layer in the board body and including a first section;
- and
- a second signal conductor layer in the board body and including a third section;
- wherein
- a line width direction of the first signal conductor layer is defined as a signal-conductor-layer left-right direction;
- a direction in which the first signal conductor layer extends is defined as a signal-conductor-layer front-back direction;
- when viewed in a stacking direction of the plurality of insulator layers, the first section is positioned leftward of the third section in the signal-conductor-layer left-right direction and extends in parallel or substantially in parallel with the third section in the signal-conductor-layer front-back direction;
- the first section includes a plurality of first thin line portions and a plurality of first thick line portions, each of the plurality of first thick line portions having a line width greater than a line width of each of the plurality of first thin line portion;
- the plurality of first thin line portions and the plurality of first thick line portions are alternately arranged in the signal-conductor-layer front-back direction;
- and
- a distance between the plurality of thin portions and the third section is greater than a distance between the plurality of thick portions and the third section.
