Punching Registration Defect Analysis and Improvement

文章通过介绍冲槽机冲孔原理和分析冲槽模具间隙对冲孔断面的影响,针对对位错品质报废率上升的原因分析采取冲槽模具设备改造措施,完成品质改善,为公司制作高难度板内层对位缺陷改善和控制起到了关键作用;同时,设备改造技术推广直接产生巨额经济节余。

This paper analyzed the effect of the different clearance between the Top-Die and Bottom-Die. It pointed out that the clearance affects the quality of the section, and the poor quality may lead poor registration. In practice, by improving the punch machine, the quality of punching was highly improved, which plays the key role on improving the quality of high layer PCB. At the same time, it gets much economic value.
