Abstract

通过对电阻的热功率、表面积的分析,研究了PCB板中的埋入式电阻的热特性,给出了PCB板中埋入式电阻的温升的解析表达式。计算了埋入式电阻在PCB板中的不同位置的温升情况,详细讨论了多个埋入式电阻的温升与单个电阻温升的关系,得到了计算具有多个埋入式电阻的PCB板的温升的方法。在设计PCB板时,大功率埋入式电阻应安排在板的中部,埋入式电阻的相互距离要分散并远离PCB板表面。||Thermal characteristics of embedded resistors in PCB(Printed Circuit Board)were studied.From the investigations of powers and surface areas of embedded resistors,the parse function of temperature rise in PCB was formulated.The differences in temperature rises against various locations in a PCB with embedded resistors also were calculated.From the analysis on relationships between single resistor and multi resistors,the calculation method of temperature rise in PCB with multi embedded resistors are presented.It was observed that an embedded resistor with large power should be placed at the center of a board and each heat source should maintain a distance among each other.
