摘　　要：经对比国内外刚挠印制板生产能力,发现我们对于刚挠处图形到PP铣边距离最小仅为150μm,远低于最小100μm水平,存在较大差距。文章通过来料烘烤、设计优化(流胶口取消)、工艺方法(定位、压膜方式)等各维度探究、找到一种提升外层图形距PP铣边距离能力水平的方法,从而提升竞争力。After comparing the capability of domestic and foreign PCB factories,it is found that the min distance from the rigid flexure figure to PP milling edge is only 150μm,which is far lower than the min 100μm level.There is a large gap.In this paper,through the research on incoming material baking,design optimization(the glue flow port is cancelled),the process method(positioning,film pressing method)and other dimensions,it found a method to improve the capability level of the distance between the outer graphics and the PP milling edge,so as to enhance the competitiveness of manufacturers.
