紫外激光器打标日益提高的系统应运
Release time:2021/09/15
传统的丝印加工,使用制作好的图形网版,利用外部压力使字符油墨从网版的部分网孔透过,并漏印在电路板表面。网版上其余部分网孔将被堵死,不透过油墨,只在电路板表面形成空白,漏印下的油墨就形成了文字、标识、图案等。这种加工方式,价格相对便宜,加工速度较快,但存在标记效果粗糙,标识易脱落、无法标记幅面较小的PCB板、化工原料有一定的毒性等缺点。
激光打标则是利用高能量密度的激光对PCB板进行局部照射,使表层材料汽化或发生变色,从而留下永久性标记。这种非接触式加工,可在非常小的幅面标记出非常清晰的二维码,保证高精度的同时也保证了高质量,不会因高低温、酸碱性改变和外界摩擦而磨损。不需要化学物质辅助,对人员安全及环境均无负面作用。
PCB激光打标机的投入使用,以其精准性和灵活性,能弥补丝印加工的不足,大大提高生产效率和良品率,降低成本,减少污染。并且进一步的在各大加工制造业中得到应用。
