摘要
随文章通过对18μm／35μm两种底铜试板上的不同间距的线宽、BGA、SMT以及孔到线、孔到PAD等多组图形进行碱性蚀刻测试，找出不同间距、不同图形、不同底铜的碱性蚀刻补偿系数的合理数值，将其运用到genesis的高级蚀刻补偿功能上，由软件自动对线路图形进行补偿，改变目前固定补偿以及凭工程人员个人经验判断来确定不同间距的图形蚀刻补偿值的做法，既能提高效率，又可改善品质。
The reasonable value of the alkaline etching test of Hoz/1 oz with two kinds of copper was tested in different spacing of the line width, BGA, SMT and hole to line, hole to pad and other groups of graphics, to find out the alkaline etching compensation coefficient of the different spacing, different graphics and different basic copper. By the use of software automatic compensation, change currently fixed compensation and by engineering personal experience and judgments to determine different spacing pattem etching compensation value approach, it can improve efficiency and quality.
