A printed circuit board (PCB) includes a base board, a conductive pattern arranged on the base board, and a number of metal pads arranged on the base board. The conductive pattern includes a number of vias and traces. The metal pads are evenly arrayed where there is a sparsity of vias and traces to balance a current during a plating process for achieving an even plating thickness. A method of designing the PCB includes: simulating a PCB with electronic components using a software, simulating vias, traces, and metal pads, and testing the electrical characteristics of the whole simulation. If the simulated PCB fails testing then it is redesigned. Once a simulated PCB passes testing then it is ready to be manufactured.
