Patent number: 7925999Abstract: A design method of printed circuit boards includes the following steps. First, simulate a printed circuit board including power layers, and vias connected to all the power layers. Then, change connections of the vias that tend to draw too much current to be connected to fewer power layers, than the vias that tend to draw less current. Repeat adjusting connections of the vias until all vias draw a similar amount of current such that no via draws more current than an upper limit the vias are designed for. Finally, according to the results, design/fabricate a PCB with vias respectively insulated, as needed, from the power layers that do not need to be connected to the vias.Type: GrantFiled: June 17, 2008Date of Patent: April 12, 2011Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Ying-Tso Lai, Chien-Hung Liu, Shou-Kuo Hsu
