摘要： A printed circuit board includes a first trace layer, a first dielectric layer, a second trace layer, a second dielectric layer, a third trace layer, a third dielectric layer and a fourth trace layer arranged in that order. A cavity is defined in the printed circuit board running through from the fourth trace layer to the second dielectric layer. Portion of the second dielectric layer is exposed in the cavity. Surfaces of the fourth trace layer combining with the second dielectric layer, and surfaces of the second trace layer combining with the first dielectric layer, are all roughened to increase the strength of adhesion.

摘要： A printed circuit board includes a base, a number of conductive pads, a dielectric layer, an activated metal layer, a first metal seed layer, a second metal seed layer, and a plurality of metal bumps. The conductive pads are formed on the base. The dielectric layer is formed on a surface of the conductive pads and portions of the base are exposed from the conductive pads. The dielectric layer includes blind vias corresponding to the conductive pads, and a laser-activated catalyst. The activated metal layer is obtained by laser irradiation at the wall of the blind via. The activated metal layer is in contact with the dielectric layer. The second metal seed layer is formed on the activated metal layer and the conductive pads. Each metal bump is formed on the second metal seed layer, and each metal bump protrudes from the dielectric layer.
