摘要
由于印刷线路板的线宽和线间间隔的细微化 ,以往不引人注意的离子迁移现象已经对线路板的绝缘性能造成影响。介绍了这种现象发生的原因和研究动向。产生离子迁移 ,并成为影响绝缘性能的因素有印刷线路板的材质及加工工艺 。
Due to the wire width and the space between wires on PWB becoming finer the insulating capability of PWB is affected by ionic migration, that was not paid enough attention to for a long time. The reason of this phenomenon and the works in this respect is introduced. The factors that could make ionic migration and then influence the insulating capability of PWB include the material itself and the processing technology of PWB . While, this phenomenon is also related to the structure design of a PWB and the environment it used.
