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。
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.
