纳秒紫外绿光激光切割铜膜的应用是去除为了PET膜表面的铜

纳秒紫外绿光激光切割铜膜的应用是去除为了PET膜表面的铜

紫外线激光切割机的原理是利用半导体紫外线激光来回扫描振动镜的高能光束。紫外线激光切割机的优点是其激光为冷光源,对加工材料热影响小,加工间隙小,加工边缘光滑,无毛刺,特别适用于铜箔、超薄金属合金等超薄金属材料的切割。此外,它还广泛应用于导电金属薄膜领域。
铜箔切割的难度在于切割边缘无碳化,无毛刺,不会使铜箔变形,实现卷对卷加工模式。传统的激光切割机,如光纤激光切割机,热影响大,精度低于紫外线激光切割机。在边缘碳化的眼中,边缘的热影响将是铜箔的翘曲和变形。紫外线激光切割机采用振动镜扫描,底部采用真空吸附,冷光源减少热影响,实现铜箔的完美切割,也适用于超薄金属切割。
铜膜的应用是去除PET膜表面的铜,形成导电图。工艺要求是去除铜,无残留物,不影响导电性,不损坏PET膜。使用红外或绿光源加工这种材料要么会损坏PET膜,要么铜不够干净,导致短路。紫外线激光切割模式的优点是表面铜的热影响小,不会损坏PET。此外,工艺下部的光直接通过PET切割。
