Your electronic assemblies deserve the ultimate protection in order to enhance durability and boost performance. It’s important to ensure they undergo valuable safeguarding processes, such as conformal coating.
During the conformal coating process, a thin, polymer film is applied to circuit boards as a protective measure. Here, we will outline the benefits of this process so you can understand how it may improve the performance of your electronic assemblies.

A Closer Look at the Application Process
There are various methods involved in the conformal coating application process. These coatings can be applied through spraying, dipping or brushing.
Traditional conformal coatings have a resin base, such as acrylic, silicone, or urethane resin, and can be diluted with a solvent. While these types of coatings are not fully waterproof, they do provide resistance to outside contaminants which ultimately improves PCB performance.
Another application method involves epoxy conformal coating, which creates very hard and durable coatings. These, however, are difficult to remove. Epoxy coatings have very high chemical resistance and are ideal for potting components.
Parylene film coatings are applied by vapor phase deposition and can be applied very thinly. These types of coatings are very resistant to moisture and extreme temperatures, making them an ideal choice for assemblies that need to withstand tough conditions.
Advantages of Conformal Coating
Electronic assemblies can encounter several issues that can impact or even hinder performance. Moisture can infiltrate assemblies and lead to corrosion and damage. Extreme temperatures can also lead to damage and performance degradation, as can bending or dropping assemblies. Conformal coating can help protect assemblies from these elements. It creates a strong barrier between moisture, chemicals, and corrosive contaminants.
It can also improve functionality and overall quality because conformal coating protects against dust, abrasion, and extreme temperatures. It insulates circuits thermally and electronically, which can prevent performance issues. Conformal coating ultimately extends product life, which can save you money in the long run.
