  1. The edges of the input end and the output end should avoid being adjacent to and parallel to each other.
    so as not to cause reflection interference. If necessary, the ground wire should be added for isolation.
    The wiring of two adjacent layers should be perpendicular to each other.
    Parallel simply creates parasitic coupling.<\/li>\n<\/ol>\n\n\n\n

    1. Add a decoupling capacitor between the power supply and the ground wire.
      Widen the width of power supply and ground wire as far as possible,
      Most preferably, the ground wire is wider than the power wire,
      Their relationship is: ground wire>power wire>signal wire,
      Usually the signal line width is: 0.2~0.3mm, the most thinner width can reach 0.05~0.07mm,
      The power line is 1.2~2.5mm\n
