Abstract
A circuit board includes a substrate and a first metal circuit layer. The substrate has an upper surface and a lower surface opposite to the upper surface. The first metal circuit layer is located on the upper surface, and the first metal circuit layer includes a first line area and a second line area. The first line area and the second line area are separated by a groove area, and the groove area includes a bent section. Accordingly, the risk of detachment between the first metal circuit layer and the substrate due to stress concentration on the circuit board can be reduced.
Claims15
A circuit board, comprising:
- a substrate having an upper surface and a lower surface opposite to the upper surface;
- and
- a first metal circuit layer located on the upper surface, wherein the first metal circuit layer includes a first area and a second area;
- wherein the first area and the second area are separated by a linear groove area, and the groove area defines a plurality of alternating bent sections;
- wherein the first area has a first boundary formed with a plurality of repetitive protruding patterns, each of the protruding patterns is defined by a first bent line having a first convex portion, a first connection portion, and a first concave portion;
- wherein each of the plurality of protruding patterns has identical shape and size;
- and
- wherein a distance defined between each of the first convex portion and the corresponding first concave portion of the plurality of the protruding patterns are identical.
