Application of plasma processor in FPC/PCB circuit board field

The manufacturing of PCB circuit boards is a very complicated process. Basically, corresponding machines and equipment are required for processing and manufacturing at each stage of production, which requires a lot of energy and production costs. A good PCB circuit board has a great impact on the production line equipment, especially for many difficult boards, which require higher equipment. FPC has greatly reduced the total weight and volume, has high bending flexibility, and adapts to the trend of lightweight and flexible electronic products. It is gradually replacing hard boards in connection functions and has become an important connecting component in electrical equipment. According to professional market research reports, the demand for FPC around the world increases by 5%-10% each year.

The application of plasma cleaning machines in the field of PCB circuit boards will improve many fields with the advancement of scientific and technological innovation.

Plasma cleaning machines often appear in various fields. We all know that circuit boards are difficult to clean. Manual cleaning can only clean what you can see with your eyes. How much dust can be invisible to the human eye? We can remove glue residue from multi-layer oily boards, soft and hard combined boards, high aspect ratio FR-4 hard board micropores, and high TG hard boards based on plasma bombardment; plasma treatment can remove foreign matter, oxide film, fingerprint recognition, oil stains, etc. on the surface, and can make the surface concave and rough, so that the bonding force is significantly improved.

Plasma treatment can remove pollution, etch the surface to improve adhesion, and provide surface activation in the electronic manufacturing process. Surface activation through plasma treatment can enhance mold attachment, molding, lead bonding and bottom filling by enhancing fluid flow, eliminating gaps and increasing wicking speed.

In a vacuum chamber, a high-energy disordered plasma is generated under a certain pressure by igniting the RF power supply, and the surface of the cleaned product is bombarded by plasma to achieve the cleaning purpose.

The principle of plasma treatment is to use the "active effect" of active particles in plasma to remove stains on the surface of objects. In terms of reaction principle, plasma treatment usually includes the following processes: inorganic gas is excited into plasma state; gas phase substances are adsorbed on the solid surface; adsorbed groups react with solid surface molecules to generate product molecules; product molecules are decomposed to form gas phase; reaction residues are separated from the surface.
