摘要
本篇文章讨论的是采用两种基材制作四层埋入电容印制板的方法FR-4基材和FR-406电容材料分别经过单面 图形转移,再经层压到外层制作的路线完成此四层板尺寸变化较小,能够很好地配合高层数多层板的工艺制作。
In this paper, we discuss an innovated technology of embedding capacitance in PWB by using two kind of laminares. Firstly we etch single-sided pattern with FR-4 and FR-406, then laminate the two materials, finally fabricate the outlayer patterns. This method has not only a better dimensional consistence than other ways, but it could be very compatible with super multilayer pcb technology.
