    摘要: A printed circuit board (PCB) and method of forming same is performed without incoming lines for plating. The plating is preferably performed on ball pad areas and/or bonding pad areas being the top layer of a multi-layer PCB. A metal layer that later forms circuit patterns serves to supply a power for plating ball pads for solder-ball bonding and bonding pads for wire-bonding with gold (Au). Thus, the gold (Au)-plating is performed prior to forming the circuit patterns. A positive-type first photoresist is coated on the metal layer to form the ball pads and the bonding pads. The coated first photoresist is also used to form circuit patterns. The gold (Au)-plated metal layer of ball pad areas and the bonding pad areas are protected by a second photoresist, which is reactive with a larger quantity of light than the first photoresist. Both first and second photoresists can be concurrently developed.

    摘要: A solar cell using a printed circuit board (PCB) includes a substrate that is formed of an insulating material and in and through which a plurality of fixing holes and communication holes are alternately formed; a plurality of photoelectric effect generators that have ball or polyhedral shapes fixed to the substrate to be disposed over the plurality of fixing holes, and generate photoelectric effects by receiving light through light-receiving portions that are exposed to an upper portion of the substrate; a plurality of upper electrodes that are formed on a top surface of the substrate, and are connected to the respective light-receiving portions of the photoelectric effect generators; and a plurality of lower electrodes that are formed on a bottom surface of the substrate to be connected to respective non-light-receiving portions of the photoelectric effect generators, and communicate with the plurality of upper electrodes through the plurality of communication holes.
