    Abstract: A package substrate having landless conductive traces is proposed, which includes a core layer with a plurality of plated through holes formed therein, and a plurality of conductive traces formed on at least a surface of the core layer. Each of the conductive traces has a connection end, a bond pad end, and a base body connecting the connection end and the bond pad end, the conductive trace is electrically connected to a corresponding one of the plated through holes through the connection end, and the connection end has a width greater than that of the base body but not greater than the diameter of the plated through hole, thereby increasing the contact area between the conductive trace and the plated through hole and preventing the contact surface of the conductive trace with the plated through hole from cracking.

    Abstract: A semiconductor package substrate is provided, which includes a substrate body having a plurality of conductive through holes formed therein, wherein at least two adjacent conductive through holes are formed as a differential pair, each of which has a ball pad formed at an end thereof; and at least one electrically integrated layer formed in the substrate body, and having an opening corresponding to the two adjacent conductive through holes formed as the differential pair and the ball pads thereof. Thus, the spacing between the conductive through holes and the electrically integrated layer and the spacing between the ball pads can be enlarged by the opening, so as to balance the impedance match.

    Abstract: A nickel/gold (Ni/Au) pad structure of a semiconductor package and a fabrication method thereof are provided. The fabrication method includes preparing a core layer; forming a conductive trace layer on the core layer; patterning the conductive trace layer to form at least one pad of the conductive trace layer; applying a conductive layer; forming a photoresist layer to define a predetermined plating region on the pad, wherein the predetermined plating region is smaller in area than the pad; forming a Ni/Au layer on the predetermined plating region; removing the photoresist layer and etching away the conductive layer; and applying a solder mask layer and forming at least one opening in the solder mask layer to expose the pad, wherein the opening is larger in area than the Ni/Au layer. The Ni/Au pad structure fabricated by the above method can prevent a solder extrusion effect incurred in the conventional technology.
