PCB layout becomes more and more important for computer systems because of the trend to faster, higher integrated, smaller form factors,and lower power systems using the PCIe® interface. The higher the switching frequencies are, the more radiation occurs on a PCB. With good layout, many EMI problems like reflection or crosstalk can be minimized to meet the required specifications.
