MATLAB在PCB爬电距离测量中的应用
Application of MATLAB Software to Measuring the Creepage
Distance of PCB
摘要 根据GB 4943.1-2011对爬电距离测量方法的具体要求,介绍了一种应用MATLAB计算PCB爬电距离的方法:即通过MATLAB最小二乘法拟合得出导电体及沟槽边沿的曲线函数,再通过MATLAB编程计算得出较为精确的爬电距离值。

Abstract According to specific requirements for the creepage distance measurement
described in GB 4943.1-2011,a method of measuring the creepage distance of PCB with
MATLAB software is introduced. By calling the least-square fitting order of MATLAB, it is
looking for the curve functions of conductive parts and groove edges,and then MATLAB
programming is used to calculate the value of creepage distance.
