How to choose the protective layer of the PCB board?- YMUS ultrasonic spraying
The performance of a PCB can be affected by many external or environmental factors, such as moisture, extreme temperatures, salt spray, and chemicals. A protective coating is a thin film of polymer applied to the surface of a PCB to protect the PCB board and its components from corrosion and environmental contamination.
By protecting against contaminants and environmental factors, protective coatings prevent corrosion of conductors, solder joints, and lines. In addition, it acts as an insulating agent, thereby reducing the effects of thermal and mechanical stress on the components. Protective coatings are an important part of printed circuit boards, usually between 50-200um thickness, and are widely used in aerospace, automotive, military, marine, lighting, consumer electronics, and industrial industries.
Ultrasonic spraying technology is used in a wide range of protective coatings in PCB (Printed Circuit Board) preparation, covering a wide range of industries and fields.
Applications:
Consumer electronics: such as smartphones, tablets, TVs, etc. Protective coating can provide moisture-proof, dust-proof, anti-corrosion and other functions to protect the stability and reliability of the circuit board.
Industrial control equipment: PCB board protective coating for industrial control equipment, such as PLC (programmable logic controller), industrial automation equipment, etc. Protective coatings can provide dustproof, anti-corrosion, anti-vibration and other functions to protect the stability and reliability of circuit boards in harsh industrial environments.
Automotive electronics: such as car navigation systems, car entertainment systems, etc. Protective coatings can provide moisture, dust, vibration, corrosion and other functions to protect the stability and reliability of circuit boards in vehicle vibration and harsh environments.
Advantages & Advantages:
Uniformity: Achieve uniform distribution of the solution, avoid uneven thickness of the coating, and provide better protection performance.
Controllability: Precise control of the thickness and composition of the coating.
High efficiency: The customized production line can quickly coat the entire PCB surface to improve production efficiency and process controllability.
Cost saving: reduce paint waste, improve material utilization, and reduce production costs.
