利用激光照射掺杂金属络合物的非金属材料,可使被照射过的区域经过敏化处理后,进行化学镀铜、镀镍等,进而形成导电通道,呈现出金属导体的性质,而没有经过激光照射的区域仍然保持原有的非金属特性。实验采用Nd:YAG激光器,经声光调制后,通过动态聚焦系统和二维振镜实现三维扫描,并经过f-theta透镜聚焦到金属络合物表面。通过调制频率1,3,10和20 kHz的激光调制进行对比实验,实现镀铜层厚度11μm以上,镀镍层厚度2μm以上,在同一种材料表面实现了金属和非金属特性共存的状态。
By irradiating the nonmetallic material doped with the metal complex with a laser, the irradiated area can be sensitized and then electroless copper plating, nickel plating and the like can be formed to form the conductive path, showing the properties of the metal conductor without The laser-irradiated area still retains the original non-metallic properties. Nd: YAG laser was used in the experiment. After acousto-optic modulation, the three-dimensional scanning was realized by dynamic focusing system and two-dimensional galvanometer, and was focused on the surface of metal complex through f-theta lens. By modulating the laser modulation with frequency of 1, 3, 10 and 20 kHz, the thickness of copper plating layer is over 11μm and the thickness of nickel plating layer is above 2μm. The coexistence of metal and nonmetallic properties on the same material surface is achieved.
