摘要
随着印制电路板向无卤、无铅、高速和高频等方向快速发展,为了达到相关性能需求,类陶瓷和石英粉等材料在基板中的填充占比越来越高,从而对印制电路板成型加工用硬质合金铣刀的冲击越来越大。通过对密齿型铣刀刃型、螺旋角和芯径进行正交试验设计,综合对比不同设计方案的铣刀在板边质量、排屑效果、刀具磨损及使用寿命的差异,最终得出了铣削性能较优的设计方案。
With the rapid development of printed circuit board towards halogen-free,lead-free,high speed,high frequency and etc,the filler of ceramic and quartz powder in the substrate is used more and more,and its impact on router bits used in PCB machining is becoming more and more severe.In this paper,the orthogonal test is designed with cutting edge shape,spiral angle and the core diameter of the dense tooth router bit into consideration,the differences of the board quality,chip evacution,tool wear and life are compared,and an optimal design of the router bit is finally obtained.
