1. Advantages and Disadvantages of Traditional Processing Technology
Changzhou MEN Intelligent Technology’s solution for laser micromachining system of electronic instruments is mainly divided into three parts: laser cutting machine,laser marking machine and laser welding machine. The demand for laser micromachining equipment mainly lies in the structural characteristics of electronic devices. On the one hand, electronic instruments have various materials & shapes, and complex structures. On the other hand, its pipe wall is relatively thin and its processing accuracy is relatively high.
Typical cases include SMT template, laptop shell, mobile phone back cover, touch pen tube, electronic cigarette tube, media beverage straw, automobile valve core, valve core tube, heat dissipation tube, electronic tube and other products. At present, the traditional processing technologies, such as turning, milling, grinding, wire cutting, stamping, high-speed drilling, chemical etching, injection molding, MIM process, 3D printing, have their own advantages and disadvantages.
Such as turning, it has a wide variety of processing materials. Its surface processing quality is good and the processing cost is moderate, but it is not suitable for processing thin-wall products. The same is for milling and grinding. The surface of wire cutting is really good, but the processing efficiency is low. The stamping efficiency is very high, the cost is relatively low, and the machining shape is relatively good, but the stamping edge has burrs, and its indication accuracy are relatively low. The efficiency of chemical etching is very high, But the key is that it is related to environmental protection, which is an increasingly prominent contradiction. In recent years, Shenzhen has very strict requirements on environmental protection, so many factories engaged in chemical etching have moved out, which is some of the main problems in the architecture of electronic devices.
In the field of fine machining of precision thin-walled parts, laser technology has the characteristics of strong complementarity with traditional machining technology, and has become a new technology with wider market demand.
In the field of fine machining of precision thin-walled parts, the micromachining pipe cutting equipment developed by us is highly complementary to the traditional machining process. In terms of laser cutting, it can process any complex opening shape of metal and non-metallic materials, with convenient proofing and low proofing cost. High machining accuracy (± 0.01mm), small cutting seam width, high machining efficiency and a small amount adhering slag. High processing yield, generally not less than 98%; In terms of laser welding, most of them are still in the interconnection of metals, and some are welding of non-metallic materials, such as sealing welding between medical tube fittings, and welding of transparent injection molded parts of automobiles; Laser marking can engrave any graphics (serial number, QR code, logo, etc.) on the surface of metal and non-metallic materials. The disadvantage of laser cutting is that it can only be processed in a single piece,, resulting in that its cost is still higher than that of machining in some cases.
At present, the application of laser micromachining equipment in electronic instrument processing mainly includes the following. Laser cutting, including SMT stainless steel template, copper, aluminum, molybdenum, nickel titanium, tungsten, magnesium, titanium sheet, magnesium alloy, stainless steel, carbon fiber ABCD parts, ceramics, FPC electronic circuit board, touch pen stainless steel tube fittings, aluminum speaker, purifier and other smart appliances; Laser welding, including stainless steel and composite battery cover; Laser marking, including aluminum, stainless steel, ceramics, plastics, mobile phone parts, electronic ceramics, etc.
