Conformal coating is a protective film applied to circuit boards to create a barrier between contaminants and the board. It acts as an insulating layer while protecting the PCB surface.

Application Consistency: Automated selective conformal coating machines equipped with specialized nozzles ensure the application of conformal coatings with exceptional accuracy and consistency.
Reduced Factory Errors: Using robotic systems to apply conformal coatings significantly reduces the risk of factory errors, resulting in higher quality products with fewer failures.
Reduced Labor: Manual processes such as taping, masking, and hand spraying, brushing, or dipping PCBAs are labor-intensive and inefficient for medium to high-volume electronics manufacturing. Automation streamlines these processes.
Cost-Savings: While the initial investment in automated conformal coating systems is higher than manual methods, the savings from reduced labor, minimized material waste, and increased production output lead to a rapid return on investment.

A conformal coating machine is a system that automates the application of protective coatings to the surfaces of printed circuit board assemblies (PCBAs). These machines are engineered for high precision and are ideal for applying coatings repetitively, ensuring consistent quality and reliability. This automation is essential for maintaining the durability and longevity of PCBAs by providing uniform coverage and safeguarding against environmental factors.

Conformal coating is applied to the surface of printed circuit board assemblies (PCBAs) either manually with a conformal coating spray gun or, more ideally, using a specialized automated robotic system. This system employs a combination of spray valves to apply the coatings with high precision and quality, utilizing various spray patterns to achieve the desired coating effect.

Conformal coating protects the electrical components on a PCB or PCBA and helps prevent failure in its intended environment. It acts as a barrier against factors like dust, moisture, temperature fluctuations, and physical shock. Different types of conformal coatings are formulated to address specific environmental challenges, ensuring the durability and reliability of the electronic assembly.
