印制板内层定位控制和PerfecTest软件

Inner-layer Registration Control and PerfecTest Software

本文探讨了影响多层印制电路板中90％以上的定位问题的五个工艺变量,介绍如何使用PerfecTest软件计算位 置的极坐标,作材料膨胀方面的修正等。

In this article,we discuss five process variables that contribute more than 90% of all rigistration problems in multilayer PCBs,and introduce how to use Perfec Test software to calculate the polar coordinates of worst case position on each panel,and to correct for material expansion,etc.
