摘要:
A surface laminar circuit board includes an insulating layer, and a signal ground conductive layer disposed on an upper surface of the insulating layer. The conductive layer has a hole formed therein. A photosensitive dielectric layer is disposed on an upper surface of the signal ground conductive layer. The dielectric layer has a photo micro-via formed therein. A signal trace is disposed on the photosensitive dielectric layer, and is electrically coupled with the signal ground conductive layer by way of the photo micro-via. A conductive pad is provided, which has a majority thereof within an area defined by an outer periphery of the hole. The conductive pad is electrically coupled with the signal trace. A surface mounted component is mounted on the conductive pad.
