PCB线宽检测设备的发展现状与趋势

印制电路板(PCB)在向高密度化和高性能化方向发展,导线精细化已成PCB生产的必然要求。在导体精细化过程中控制上线宽度和下线宽度以保证导线的电特性要求,已成各PCB生产厂家急需解决的关键问题。本文通过对目前常用PCB线宽检测设备的优缺点进行分析,提出了采用数字图像处理技术与照明技术的新一代的线宽/间距检测仪器设备,将成为印制板厂线宽检测的必备测量工具。

The Development status and trends of the PCB line and width measurement equipment

With the development of the high density and capability PCB,fine line conductors are necessary in the process of the PCB production.In order to ensure the electrical characteristics,controlling the top line width and bottom line width of the fine wire conductors becomes the key problem that the PCB manufactures have to solve urgently.In this article,the relative merits of the commonly line width measurement equipment used in PCB at present are discussed.A new generation line width/space measurement equipmen...
