What Is Silicone Conformal Coating Material For PCB Standards?
Conformal coatings are applied to offer protection to printed circuit boards, also referred to as PCBs. Thin coatings are applied to electronic components to protect them from chemical, mechanical, and physical damage. Silicone coating has become very popular over the years because it works amazingly well even where other conformal coatings fail. It is a coating type that represents advancements toward modern electronic protection.
What is it?
Silicon conformal coating is made using silicone resin. The resin protects PCBs from all kinds of temperatures, making it superior to other types of coatings. It is resistant to chemicals, vibration, and moisture. It is, however, important to remember that silicone conformal coating can be hard to repair or remove.
What makes it unique?
Silicone has unique characteristics which have made it popular in different electronic applications. The coating adheres to most board materials and is featured on IPC electronics standards for modern PCBs. It is also compatible with thermal paste, a key component on high-temperature PCBs.
Silicon coating repels water with proper application. It, however, has the probability of absorbing water during application compared to other coatings. When applying, therefore, precision is crucial to achieving even coatings with no defects where water can collect. When water manages to collect, the coating erodes with time, and its lifespan is disrupted. This type of conformal coating is rubbery in nature, and whereas this gives it resilience, it can change thickness and flow over time.
Silicone coating is flexible. This is a very important characteristic considering that many circuits are flexible too. This allows them to bend into shapes that would otherwise be impossible using rigid boards. Such flexible boards require a conformal coating that is just as flexible; silicone passes the test. It bends, offering even protection where other coatings fail.
Silicone conformal coating is cost-effective. Even though this coating is high-risk because of how hard it is to remove, it is cost-effective with proper application. The coating requires very careful application and planning for the best results to be achieved. Small mistakes during the application can be costly; removing the coating to correct the error will leave the board vulnerable to chemical and physical damage. Luckily, there are reliable silicone conformal coating services that you can use to eliminate the chances of mistakes happening during the application. The service providers have what it takes in terms of experience, knowledge, and machinery to fetch you great results with silicone coatings.
Silicone coating withstands extreme temperatures. This characteristic has made silicone conformal coatings popular in the fast-growing market. Many industries apply the resin because extreme temperatures and stresses do not disintegrate it. It is the best type of coating for boards that work over long periods and in hot settings like automotive parts. The innate ability of silicone to withstand higher temperature exposure for a long time makes it a primary choice for aerospace and industrial applications. The coating can also be applied to ticker films as a vibration dampener or isolation tool. The same can be done if coated assemblies are meant for high-vibration environments.
Silicone conformal coatings are quite reliable, but the application has to be done right for optimal performance. You can seek professional services bound to nail the coating on the first trial to keep your costs friendly.
