Abstract: A method for increasing a production rate of printed wiring boards has the following steps: applying a conductive layer to an isolating base board; drilling at least one first conductive layer and the isolating base board to form multiple through holes; plating the through holes with a conductive material to form an inner conductive layer; implementing a plating process; plating the set of wires with a conductive material such as copper to form a third conductive layer and thereby increasing a width of each wiring and shorten a distance between adjacent wires; and applying a solder resist on portions of the wires. The method of the invention maintains the width of the wiring in an appropriate value by plating the wiring. Therefore, the quality and the production rate of printed wiring boards are improved.
