Surface treatment of electronic products is an important link in the manufacturing industry. It can enhance the appearance of products, improve durability and endow them with special functions.

The following are some common surface treatments and processing techniques

1. Spraying: The coating is evenly applied to the product surface through spraying equipment to form a protective film, enhancing the product's corrosion resistance and aesthetic appeal.

2. Electroplating: By using the principle of electrolysis, a layer of metal or alloy is deposited on the surface of a product to enhance its electrical conductivity, corrosion resistance or decorative properties.

3. Anodic oxidation: It is applicable to the surface of metals and forms an oxide film through electrochemical methods, enhancing the hardness and wear resistance of metals.

4. Polishing: Remove the rough parts on the product surface by mechanical or chemical methods to achieve a smooth and bright surface effect.

5. Sandblasting: By using high-speed sand particles to clean the surface of the product, dirt and oxide layers are removed to prepare for subsequent processing.

6. Laser marking: It uses laser technology to engrave text, patterns and other information on the surface of products, featuring high precision and permanence.

The selection of these surface treatments and processing techniques depends on the material, application and aesthetic requirements of the product. Through reasonable surface treatment and processing techniques, the quality and competitiveness of products can be enhanced.
