Laser marking technology for electronic components
With the fast development of the electronic technology, the speed of upgrading of the electronic products are becoming quicker and quicker. Therefore, the electronic manufacturing enterprises are required to provide more cost-benefit products to the market at a faster speed. A complete set of data traceability system must be established for the product from storing, manufacturing, inspecting to delivering, so as to realize the internal control of the product quality. In order to realize the product traceability, character or bar code identifications have to be made to the product, thus endowing the product with the unique "ID Card".
At present, most electronic products, such as the main board of the mobile phone, computer and other key elements have identifications of traceable information. At the present stage, it is commonly adopted the ink label paper to stick on the product. However, such a mean has many problems, big amount of consumables, high pollution, high labor cost, the marks are easy to be eliminated and so on. Aimed at such condition, replacing the label paper by the laser marking code has become a tendency of the industry. With the automatic PCB laser marking machine, matrix code, two-dimension barcode and character, pattern and other information can be marked on the printing circuit board and the relevant components. The laser marking machine integrates the high-performance CO2/Fiber light source and high-pixel CCD camera. Combined with the micron-level mobile module, the automatic positioning before coding as well as the automatic code interpreting and assessing after coding can be realized. Through special software, this device can realize connecting with the customer information system. The marked information can be generated with the software system automatically and can be received through the internet. It can be coordinated with the online operation of the SMT production line. Furthermore, it can also cooperate with the automatic up and down trigger to constitute the off-line operation station.
