    The working principle and application scope of metal etching equipment

    發布時間:2021-01-06
    Etching refers to the process of exposing and developing a plate, removing the protection of the etched area, and coming into contact with a chemical solution during the etching process to achieve dissolution and corrosion effects, forming a concave convex or hollow molding effect. It was originally used to make printing relief plates such as copperplate and zinc plate. Metal etching equipment can be divided into chemical etching machines and electrolytic etching machines.


    The basic principle is to output the radio frequency generated by the ICP radio frequency power supply to a circular coupling coil under vacuum and low pressure, and couple a certain proportion of mixed etching gas to glow discharge to generate high-density plasma. Under the action of radio frequency, it is applied to the radio frequency of the lower electrode. These plasmas bombard the lower electrode on the substrate surface, and the chemical bonds of the semiconductor material in the substrate pattern area are destroyed. Volatile substances are generated with the etching gas, separated from the substrate in the form of gas, and extracted from the vacuum pipeline.


    The working principle and application scope of metal etching equipment. Chemical etching is the use of chemical solutions to achieve the purpose of etching through chemical reactions. Chemical etching machine is a technology that removes materials through chemical reactions or physical impacts.


    Electrocorrosion is the process of using the principle of metal anodic dissolution, with tap water or salt water as the main corrosive agent (under electrolysis) to corrode metals in liquid and connect the corrosion power source to achieve the purpose of corrosion.


    Advantages: No pollution, but only one etching step is not without pollution. Other processes must also be pollution-free, suitable for experimental production and small area etching of concave characters. It is mainly used on scientific research experimental machines, or simply etching traces on metals, also known as electric traces.


    Disadvantages: Uneven etching surface, slow corrosion in large areas, cannot be used for mass production, large area etching of convex characters, and cannot be used for mass production and processing of logos.


    Metal etching equipment is mainly used in the aviation, machinery, and labeling industries. Etching technology is widely used in the processing of lightweight instrument panels, nameplates, and thin workpieces that are difficult to process using traditional processing methods. Etching is an indispensable technology in the manufacturing process of semiconductors and circuit boards. It is widely used in industrial applications such as gold card label processing, mobile phone button processing, stainless steel filter processing, stainless steel elevator decorative panel processing, metal lead frame processing, metal eyeglass foot wire processing, circuit board processing, metal decorative panel processing, etc.
