Wiring board and method for manufacturing wiring board |
摘要 |
A wiring board includes an interlayer insulation layer, conductive patterns formed on the interlayer insulation layer, and a solder-resist layer formed on the interlayer insulation layer and having an opening partially exposing the conductive patterns. The solder-resist layer has an edge portion bordering the opening and intersecting the conductive patterns, and the edge portion of the solder-resist layer has a concavo-convex shape having convex portions and concave portions such that the convex portions and the concave portions are alternately intersecting the conductive patterns. |

1. A wiring board, comprising:
an interlayer insulation layer; a plurality of conductive patterns formed on the interlayer insulation layer; and a solder-resist layer formed on the interlayer insulation layer and having an opening partially exposing the plurality of conductive patterns, wherein the solder-resist layer has an edge portion bordering the opening and intersecting the conductive patterns, the edge portion of the solder-resist layer has a concavo-convex shape having a plurality of convex portions and a plurality of concave portions such that the convex portions and the concave portions are alternately intersecting the conductive patterns, and the concavo-convex shape of the edge portion has the convex portions and concave portions in at least one of a wave form in a cycle and rectangular forms. |
