项目摘要
This paper describes an evaluation of effective thermal conductivities of Printed CircuitBoards (PCBs) for thermal design of electronic equipment. To formulate the in-plane effectivethermal conductivity of the PCBs, we define two types of a thermal resistance by usingspreading resistance equation. One is the thermal resistance as a function of the thermalconductivity of copper wire and of base material, and the other is that of effective thermalconductivities. The thermal resistance by using the thermal conductivity of copper wire and ofbase material is almost matched with experimental results when heat diffusion radius inin-plane direction by copper wire is about 26.5 mm. On the other hand, the thermal resistanceby using effective thermal conductivities is in good agreement with experimental results whenwe multiply 1D thermal resistance term in the proposed equation by 0.45. Therefore, in-planeeffective thermal conductivity of the PCBs can be evaluated by using proposed equations
本文介绍了用于电子设备热设计的印刷电路板 (PCB) 有效导热率的评估。为了制定 PCB 的面内有效导热系数,我们使用传播电阻方程定义了两种类型的热阻。一个是作为铜线和基材热导率函数的热阻,另一个是有效热导率。当铜线面内方向的热扩散半径约为26.5 mm时,利用铜线和基材的导热系数得到的热阻与实验结果几乎相符。另一方面,当我们将方程中的一维热阻项乘以0.45时,使用有效热导率得到的热阻与实验结果非常吻合。因此,可以使用提出的方程来评估 PCB 的面内有效热导率
