Metal corrosion processing overall etching process

Metal corrosion processing is a widely used technology in the industrial field to achieve a predetermined shape, size and surface quality by treating the metal surface. Integral etching processing is an important method in metal corrosion processing with high precision, high speed and high efficiency, which is widely used in microelectronics, optoelectronics, biomedical and other fields. This article will introduce the metal corrosion processing overall etching process in detail.

Metal corrosion processing is the metal material through chemical or electrochemical reaction, so that its surface changes to meet the predetermined requirements of the process. According to the different treatment methods, metal corrosion processing can be divided into physical corrosion, chemical corrosion and electrochemical corrosion. Integral etching processing belongs to a kind of electrochemical corrosion, which dissolves and removes the metal surface through electrolytic reaction to achieve the predetermined shape and size.

In the etching process before, need to do the following preparatory work:

1. Selection of materials: according to the processing requirements to select the appropriate metal materials, such as copper, nickel, gold, etc..

2. Plate making: make a mask plate according to the design requirements, cover the areas that do not need to be corroded, in order to protect these areas from the corrosive agent.

3. Printing: the mask version of the graphics transferred to the metal surface, commonly used printing methods such as photolithography and electroplating.

The specific steps and characteristics of various corrosion processing methods

1. Wet corrosion: the metal surface is immersed in the corrosive agent, through chemical reaction to dissolve the metal surface to remove. Wet corrosion is characterized by simple operation, low cost, but the speed is slow, precision is not easy to control.

2. Dry corrosion: the use of dry corrosive agent on the metal surface corrosion treatment. Dry corrosion speed, high precision, but need to strictly control the temperature and pressure, otherwise easy to produce pores and cracks.

3. Electrochemical corrosion: the metal surface is dissolved and removed through electrolytic reaction to achieve the predetermined shape and size. Electrochemical corrosion is characterized by high precision and high efficiency, and is one of the commonly used methods in the overall etching process.

In the process of etching processing, the following issues and precautions need to be noted:

1. Safety issues: the chemical reagents and electrochemical reagents used in the etching process are hazardous, and need to take good safety measures to avoid harm to the human body and the environment.

2. Process: different types of corrosion processing methods have different processes and operating standards, need to strictly comply with the operating procedures to ensure the quality and efficiency of processing.

3. Quality control: the quality of the metal surface after corrosion processing has an important impact on the performance and service life of the final product, and it is necessary to strictly control the processing and final quality to ensure that it meets the design requirements.

The overall etching process is characterized by high precision, high speed and high efficiency, and is widely used in microelectronics, optoelectronics, biomedical and other fields. Specific applications are as follows:

1. Microelectronics: In the field of microelectronics, the overall etching process is used to manufacture integrated circuits, microprocessors, sensors and other tiny parts. Through high-precision and high-efficiency etching processing, it is possible to obtain microscopic devices with smooth surfaces and precise structures.

2. Optoelectronics field: In the field of optoelectronics, the overall etching process is used to manufacture lasers, solar cells, optoelectronic devices and so on. Through the precise etching process, low-loss, high-efficiency optical components can be obtained.

3. Biomedical field: In the biomedical field, the overall etching processing is used to manufacture artificial joints, implants and other medical devices. Through strict process control and sterilization measures, high-performance, safe medical devices can be obtained.
