3C is computer, communication and consumer electronics. Nowadays, a number of IT industries are marching towards the 3C area and taking the combination of 3C with technology products as a breakthrough of their development. 3C electronic products play various roles in people's daily life, such as providing information, offering convenience and inspiring creativity. Being lighter, thinner and more portable have become the goal of designers, which has also brought continuous progress of new materials and new techniques. Laser has become the representative in the manufacturing process of 3C products.
At this stage, the laser processing technology in 3C industries are mainly laser marking, laser anodizing treatment, metal carving, laser drilling, etc. On the premise of precision machining, traditional printing, pressing and CNC have been unable to meet the rapid-growing demands and control the cost of production effectively.
