  • Patent number: 7129419
    Abstract: The present invention relates to a printed circuit board with low noise. A voltage source layer and a ground layer of the printed circuit board are divided into an analog area and a digital area respectively via an isolation line, and adapted to conduct voltage source signal and ground signal respectively. Because the isolation line is an open pattern and a capacitor adapts to position near the opening, the noise and the electro-magnetic parameter of the printed circuit board are reduced.
    Type: Grant
