Common surface treatment processes for electronic products

Surface treatment of electronic products is an important part of the manufacturing industry. They can enhance the appearance, durability and special functions of products.

The following are some common surface treatment and processing processes

1. Spraying: The paint is evenly applied to the surface of the product through spraying equipment to form a protective film to enhance the corrosion resistance and aesthetics of the product.

2. Electroplating: Using the principle of electrolysis, a layer of metal or alloy is deposited on the surface of the product to improve its conductivity, corrosion resistance or decorativeness.

3. Anodizing: Applicable to metal surfaces, an oxide film is formed by electrochemical methods to improve the hardness and wear resistance of the metal.

4. Polishing: Use mechanical or chemical methods to remove the rough parts of the product surface to achieve a smooth and bright surface effect.

5. Sandblasting: Use high-speed sand jets to clean the surface of the product, remove dirt and oxide layers, and prepare for subsequent processing.

6. Laser marking: Use laser technology to engrave text, patterns and other information on the surface of the product with high precision and permanence.

The choice of these surface treatments and processing technologies depends on the material, purpose and aesthetic requirements of the product. Through reasonable surface treatment and processing technology, the quality and competitiveness of products can be improved.
