发明名称 Support method and apparatus for printed circuit board
摘要 An orthogonal array is formed by performing electromagnetic field analysis only once and determining a range by using the mount position and type of a capacitor and the number of capacitors as parameters to perform circuit analysis a small number of times. An estimation equation is formed by using as an index a result of the absolute value of the calculated power source impedance, and a capacitor is disposed to reduce noises by using the estimation equation.
