3D激光显微镜在PCB表面粗糙度研究中的应用

摘要

In this paper, the surface roughness for PCB was studied by 3D laser scanning confocal microscope LEXT OLS4000. PCB surface roughness measurement methods are synthetically reviewed and advance direction of the research is prospected to promote the research in theory and application in the future.%文章应用LEXT OLS4000激光扫描共聚焦显微镜对印制电路板芯板表面粗糙度进行测量，论述了PCB表面粗糙度测量方法及研究现状，并对其未来的研究发展方向进行了展望，以期进一步推动理论和应用研究的工作。
