交流电流如何影响电路板线路的温度How AC Currents Affect PCB Trace Temperatures文章研究交流电流对PCB线路温度的影响,包括线路截面的负载电流占空比例、电流脉冲波形和循环周期引起线路温度的变化,通过建立模型进行验证。结论为线路的温度取决于驱动电流的等效均方根值(RMS),电流的频率和在线路占空比高会上升温度。(Douglas G.Brooks,PCD&F,2016/09,共10页)用新的刚挠板设计规则确保产品可靠
How AC Currents Affect PCB Circuit Temperatures How AC Currents Affect PCB Trace Temperatures This article examines the effects of AC current on PCB temperature, including the load current duty cycle of the line cross section, the current pulse waveform, and the change in line temperature caused by the cycle, Establish a model for verification. The conclusion is that the temperature of the line depends on the equivalent root-mean-square (RMS) value of the drive current, the frequency of the current and the rising temperature of the line at a high duty cycle.
