摘要
随着PCB(Printed circuit board,印制电路板)平面变压器的广泛应用,线圈产品的耐电压要求也越来越高,但是线圈产品的耐压设计能力却并不明确。文章通过对不同铜厚、半固化片的不同玻纤类型、不同孔间距、不同焊盘间距等的研究,使用耐电压测试仪进行测试,采用失效电压、漏电流进行表征,获得了层间、表面铜到铜(焊盘盖油及不盖油)、内层线路、孔到孔之间的耐电压能力,输出了平面变压器PCB的耐电压可靠性设计方案,并进一步软件化。
With the wide application of PCB planar transformers,the withstand voltage requirements of coil products are getting higher and higher.However,the withstand voltage design capability of coil products is not clear.In this paper,through the study of different copper thickness,different glass fiber types,different hole spacing,and different pad spacing of different copper thicknesses,different hole spacings,different pad spacings,etc.,the withstand voltage tester is used to test,and the failure voltage and leakage current are used for characterization.The paper obtained the withstand voltage capability between layers,surface copper to copper(pad with oil and no oil),inner line,and hole to hole,and concluded out the withstand voltage reliability design plan of the planar transformer PCB,and realized further by software.
