If the surface stain is caused by environmental problems, the cleaning and improvement of the air conditioning filter system should be strengthened, or the wind speed should be reduced, and the small hairs on the air conditioning filter bag must be completely removed. And the fibers and powders on the polymer materials must be completely removed, which are very easy to cause stains. The air supply pipeline is easy to use plastic material, which does not produce fiber and is easy to clean with water, acid and alkali.

With the further competition in the market, even those with high added value have to be controlled from the production cost. Because the production requires very strict cleanliness of its electrolytic solution (copper sulfate solution), many filtration systems and liquid feeding pumps are repeatedly used in previous production processes. A new process flow is provided here, which can fundamentally control product quality and reduce production costs.

Silane coupling agent treatment: after anti oxidation treatment, the surface is sprayed with silane, which can improve the oxidation resistance at room temperature on the one hand; On the other hand, in high temperature pressing plate, silane can better combine copper foil and resin substrate through coupling, and improve peel strength. Post treatment process - drying. In order to prevent the harm of residual moisture, it must be dried at not less than 100 ℃ later, and the drying temperature cannot be too high.

With the development of high-density wiring technology for low profile copper foil multilayer boards, the traditional type cannot meet the needs of manufacturing high-precision printed circuit boards. Therefore, a new generation of copper foils, low profile (LP) and ultra-low profile (VLP), have emerged one after another. Compared with ordinary electrolytic copper foil, LP copper foil has fine crystal (2/zm), equiaxed grains, no columnar crystals, lamellar crystals, flat prisms and low surface roughness.

Copper foil can be divided into calendered copper foil and electrolytic copper foil, which are mainly used for flexible printed circuits and other special purposes. In the production of clad laminates, a large number of applications are. As for the purity of copper, IEC-249-34 and Chinese standards stipulate that it shall not be lower than 99.8%.

Electrolytic copper foil is made by dissolving copper into copper sulfate solution, electrodepositing the copper sulfate electrolyte under the action of direct current in special electrolytic equipment to make the original foil, and then carrying out surface treatment, heat-resistant layer treatment, oxidation prevention treatment and other surface treatment processes on the original foil according to customer requirements.
