Abstract: Disclosed herein are a printed circuit board and a method for manufacturing the same. The printed circuit board includes: a copper pad surface roughness-treated to have a surface roughness of 0.1 to 1.0 ?m pitch period; and an electroless surface treatment plating layer formed on the copper pad. According to the present invention, when the copper pad has a surface roughness of a predetermined pitch period, the electroless surface treatment plating layer formed on the copper pad also has a surface roughness of the predetermined pitch period, thereby having an effect of widening a surface area and improving workability at the time of a wire bonding process for connection with an external device.

Abstract: Disclosed herein are an electroless surface treatment plated layer of a printed circuit board, a method for preparing the same, and printed circuit board including the same. The electroless surface treatment plated layer includes: electroless nickel (Ni) plated coating/palladium (Pd) plated coating/gold (Au) plated coating, wherein each of the electroless nickel, palladium, and gold plated coatings has a thickness of 0.02 to 1 ?m, 0.01 to 0.3 ?m, and 0.01 to 0.5 ?m. In the electroless surface treatment plated layer of the printed circuit board, a thickness of the nickel plated coating is specially minimized to 0.02 to 1 ?m, thereby making it possible to form an optimized electroless Ni/Pd/Au surface treatment plated layer.
