Circuit board with high reflectivity and method for manufacturing the same
Abstract:
A circuit board having a high reflectivity includes a wiring board, a first solder resist layer, and a second solder resist layer. The wiring board includes a wiring layer on an outer side, the wiring layer including wiring and a bond pad spaced from the wiring. The first solder resist layer, with opening and groove, covers the wiring layer, the bond pad is exposed from the opening but spaced from the first solder resist layer. The second solder resist layer infills the groove and covers the first solder resist layer but does not make contact with the mounting surface of the bond pad. A method for manufacturing such circuit board is also disclosed.
