纳秒紫外激光器打标机能加工作用于哪些材料

紫外激光打标机又称做紫外激光镭雕机,紫外线激光打标机,UV紫外线激光打标机。紫外激光打标机原理:跟普通光纤激光打标机一样,也是利用激光束在各种物质表面打码标记长久的标记,在紫外激光加工时的反应机理是通过光化学消融作用实现的,即依靠激光能量打断原子或分子间的键合,使其成为小分子气化、蒸发掉。聚焦光斑极小,且加工热影响区微乎其微,因而可以进行超精细打标、特殊材料打标。
伴随着激光设备的迅速发展,紫外激光打标机功率的提高,紫外激光打标机已经被应用于超精细加工高端市场,iPhone、化妆品、药品、食品及其他高分子材料的包装瓶表面打标;柔性PCB板打标、划片;硅晶圆片微孔、盲孔加工;LCD液晶玻璃、玻璃器皿表面、金属表面镀层、塑胶按键、电子原件、礼品、通讯器材、建筑材料等多个领域。
紫外激光加工进程称为“光蚀”效应,“冷加工”具有很高负荷能量的(紫外)光子,能够打断资料或周围介质内的化学键,至使资料发作非热进程损坏。这种冷加工在激光符号加工中具有特别的含义,因为它不是热烧蚀,而是不发生"热损伤"副作用的、打断化学键的冷剥离,因此对被加工外表的里层和邻近区域不发生加热或热变形等作用。所加工出来的资料具有润滑的边缘和极低限度的碳化.
