Throughout their lives, exposed conductors and electronic components are susceptible to mechanical or chemical deterioration. Since consumers and business users anticipate their electronics to be dependable and long-lasting, manufacturers have created strategies to shield PCBAs from harm and guarantee their continued functionality. Applying a conformal coating is one of these preventative methods. By preventing chemical damage, this technique increases the longevity and dependability of PCBAs.

Usually "Conformal Coating" means anti-humidity, anti-salt, anti-mold.

Additionally, the "Conformal Coating" enhances the insulating strength, reduces vibration and friction, guards against printed circuit assembly board (PCBA) failure, and ensures and prolongs the product's service life. Systems for industrial control, automotive electronics and power systems, aerospace systems, and strategic defense systems are only a few of the many applications for coating technology. To increase the product's lifespan, coating technology is also utilized in civilian products. The electronic assembly's coating procedure takes place at the PCBA's rear end. Following the standard procedure of SMT assembly and testing, the SMT part is completed and processed for conformal coating after passing the quality inspection. There are several ways to go about the process, including brush, spray, dip, and selective coating.

The environment has a significant effect on electronic gadgets. In addition to being intimately linked to human existence, the environment also greatly affects the stability and longevity of electronic equipment. Among the various environmental conditions that pose a direct threat to the storage and usage of electronic equipment are mold, moisture, and salt spray. Because of the unique characteristics of their usage environment, high-tech products—particularly military weapons and equipment, aerospace, navigation, power, energy, cars, and other electronic equipment that operates in the wild, especially in humid environments—are more vulnerable to these elements.

Therefore, we will add conformal coating according to the customer's requirements. Currently, the better material on the market is K50, and it is a foreign brand.

Designers must take into account a variety of elements prior to masking, and there is no one technique that is always optimal for a given masking circumstance. When choosing to use masking, a designer should consider a number of important elements, including the area to be masked, its shape, geometry, and function, as well as the degree of protection provided by the masking. The anticipated life of the masking and the difficulty of removing it, should the need arise, are other considerations for designers.

While some masking strategies are transitory, others are permanent in their ability to prevent conformal coating adhesion. Although permanent liquids and gels are widely used, new technologies have expanded the range of options for transient masking. More recently, there are temporary masking substances that can be cured using UV radiation. They don't require tangible medium like tape or shields, and they're simple to put and remove. Furthermore, they are not as constrained by board geometry as solid masking materials are. Notwithstanding these benefits, these temporary liquids need to be applied and removed with competence; while some automation is feasible, it takes a qualified technician to operate the application tools, and it's not an easy task.
