    2018-04-13 10:27:09

    With the increasing frequency of device operation, signal integrity issues faced by high-speed PCB designs have become a bottleneck in traditional designs, and engineers are faced with increasing challenges in designing complete solutions. Although relate

    Why do you want to lay copper?
    2018-04-13 10:26:23

    Meizhou Hongzhan Electronic Technology Co., Ltd. thinks that there are several reasons for laying copper in general:
    1, EMC. For a large area of ground or power supply copper, will play a shielding role, some special, such as PGND play a protective r

    DFM should not be limited to chips, PCB needs it more!
    2018-04-13 10:23:10

    Despite the many disputes surrounding the value, definition, variability, and technology of DFM, all problems are based on chips. Of course, chip DFM is a key requirement when we start thinking about 45- and 32-nanometer designs. However, the focus on
