摘　　要：随着通讯技术和FPCB行业的快速发展，对挠性印制电路板的钻孔质量和钻孔速度指标提出了更高的要求，文章介绍一种称为IFOV的激光定位技术，本技术相对于传统的Step＆Scanning技术有较多的优势，特别是在加工挠性印制电路板盲孔时，优势更为显著。文章介绍的系统搭配了11w、355nm波长的激光器，聚焦透镜焦距为100mm，实际选择非常难以加工的材料类型Cu18PI12Cu18作为测试对象，对加工盲孔后的各个数据进行分析，实验结果表明，利用IFOV技术不仅在钻孔效果、钻孔质量、孔位精度及品质稳定性方面得到保证，而且钻孔速度比传统的Step＆Scanning模式要快30％以上，IFOV控制技术应用在FPCB钻孔上的优势明显。With the rapid development of communication technology and FPCB industry, the demand for drilling productivity and quality is higher and higher. For this purpose, this paper describes a new laser beam control technology called IFOV. Compared with traditional Step ＆ Scanning technology IFOV has more advantages, especially in the case of drilling blind hole on FPCB. Equipped with 11 W ＆ 355 nm laser and the lens of focus length 100mm, this paper has drawn conclusion from the data of drilling blind hole on Cu18PI12Cu18, which is a challenging material in FPCB industry. The analysis result shows that IFOV is a substantial technology no matter on the production productivity or on the quality of holes, drilling productivity is 30% more than step ＆ scanning which shows IFOV has clear advantage.
