摘要
描述了固体倍频紫外激光在 35 5nm和 2 6 6nm ,不同聚焦透镜实验条件下 ,对多层电路板的微刻蚀实验 ,进行了其传热一维模型的理论推导 ,并得到了在实验条件下最佳的理论参数为波长 2 6 6nm ,峰值功率大于 2× 10 6J/s ,聚焦透镜焦距为 2 0 0mm 。
A technique using pulsed UV laser to process or correct the circuit boards was studied. The influences of the laser wavelengthes, pulse energy and lens focus length on the circuit ablation were investigated, and the optimal parameters were got.
