As a major manufacturing country, China’s rapid economic development has led to an increasing demand for the processing of various metal and non-metal workpieces in industrial production, which has led to a rapid expansion of the application areas of laser processing equipment. As a new “green” technology that has emerged in recent years, laser processing technology is constantly trying to integrate with many other technologies to breed new technologies and industries in the face of the ever-changing processing needs of different fields.
Glass can be found everywhere in people’s daily lives and can be considered one of the most important materials for the development of contemporary human civilization, with a lasting and far-reaching impact on modern human society. It is not only widely used in construction, automobiles, housewares and packaging, but is also a key material in cutting-edge fields such as energy, biomedicine, information and communication, electronics, aerospace, and optoelectronics. Drilling of glass is a common process, commonly used in various types of industrial substrates, display panels, civil glass, decoration, bathroom, photovoltaic and display covers for the electronics industry.
Laser glass processing has the following characteristics:
High speed, high precision, good stability, contactless processing, with a much higher yield than traditional processing processes;
The minimum diameter of glass drilling hole is 0.2mm, and any specifications such as square hole, round hole and step hole can be processed;
The use of vibrating mirror drilling processing, using the point-by-point action of a single pulse on the substrate material, with the laser focal point mounted on a predetermined designed path moving in a rapid scan across the glass to achieve the removal of the glass material;
Bottom-to-top processing, where the laser passes through the material and focuses on the lower surface, removing the material layer by layer from the bottom upwards. There is no taper in the material during the process, and the top and bottom holes are the same diameter, resulting in highly accurate and efficient “digital” glass drilling.
