摘要：Different laser parameters and the interactional production can affect the barcode grade profoundly. In order to mark barcodes on aluminum alloy with a laser effectively, it is important to search out the optimum parameters and establish a relationship between critical laser parameters and the quality of the symbol. In this research, a Nd:YAG laser was utilized to produce 3136 Data Matrix symbols onto aluminum substrates. The experiment focuses on all interval values of the vector step, inter-step time, laser Q frequency and laser Q release time. From the experiment results, the optimized parameters are the vector step of 0.005 similar to 0.009 mm, the inter-step time of 29 similar to 43 mu s, laser Q frequency of 7 similar to 10 KHz, and laser Q release time of 13 similar to 19 us. And then, by analyzing the higher and the lower power density processing module SEM images and EDS data, it was found that the microstructure and micro-components of formations that created by the interaction between the laser and the aluminum alloy can affect the barcodes grade level significantly.
