In the electronics industry, one key player consistently ensures the longevity and reliability of devices – the conformal coating. This protective chemical layer serves as a defense shield for electronic components against environmental hazards like dust, moisture, and temperature extremes. Whether it’s the smartphone in your hand, the car you’re driving, or the plane soaring in the sky, you’ll find the invisible hand of the conformal coating company at work
A Closer Look at Conformal Coating
Conformal coating is a thin polymeric film designed to ‘conform’ to the contours of a printed circuit board (PCB). Applying it improves the durability and performance of electronic assemblies. Its primary purpose is to protect electronic circuits from harsh operating environments where moisture, dust, chemicals, and temperature changes might cause damage.
The Various Types of Conformal Coating
When it comes to conformal coatings, there are several types that differ in their chemical composition and properties, making each suitable for specific applications. The common types include acrylic, silicone, and Parylene conformal coatings
Understanding the types of conformal coating is key to selecting the right one to suit specific applications. Let’s delve into the most common types provided by manufacturers and suppliers:
Acrylic Conformal Coating: Acrylic is the most widely used material owing to its easy application and removal. It offers decent moisture and abrasion resistance. However, it is not the best choice for high-temperature applications. Acrylic conformal coating is known for its ease of application, quick drying times, and good moisture resistance. Most importantly, it can be easily removed for parts rework, making it a popular choice in the electronics sector.
Silicone Conformal Coating: Known for its excellent temperature and moisture resistance, silicone conformal coating is the go-to option for high-temperature environments. It’s also flexible, making it ideal for components that may undergo thermal movement. Silicone conformal coating offers excellent high-temperature resistance, making it a preferred choice for applications subjected to extreme temperatures. This type of coating is mainly used in the automotive industry, protecting components from high engine heat.
Parylene Conformal Coating: Parylene, though on the pricier side, provides superior protection. It is chemically inert, offering excellent resistance to solvents. It’s also transparent, and its thin layer doesn’t affect the visibility of the coated parts. Parylene conformal coating is unique in its vapor deposition application process. This coating offers superb protection against chemical and moisture intrusion, making it suitable for medical devices and aerospace components.
The Conformal Coating Process
The conformal coating process generally involves four steps: cleaning, application, curing, and inspection. The process may vary slightly depending on the coating type and application method used.
The Breadth of Applications
Conformal coating finds its applications in several industries, including automotive, aerospace, medical, and industrial sectors. In the automotive industry, it protects against engine heat, while in aerospace, it shields components from temperature fluctuations. Medical devices use it to maintain their hygiene standards, and it ensures reliability in harsh industrial environments.
Selecting the right conformal coating and process can be tricky, given the array of choices. It’s crucial to partner with a reliable conformal coating company to make the right selection and achieve the best results.

The Conformal Coating Process
The conformal coating process begins with cleaning the board or component to remove any residue or contaminants. The next step is the application of the coating. This can be done in various ways, including dipping, brushing, and spraying. The method chosen largely depends on the component and the type of coating used.
After application, the coating is cured to solidify and adhere to the surface of the component. The curing process varies from type to type; some coatings cure at room temperature, while others require heat. A final inspection is then conducted to ensure the coating has been applied correctly and evenly, providing the required protection.
Material Selection in Conformal Coating
The choice of conformal coating material plays a significant role in the success of the coating process. It’s important to consider factors such as the operating environment, component material, and desired protection level when selecting a coating material. Each type of coating offers unique benefits and can be tailored to meet specific industry requirements.
While selecting a conformal coating, it’s also important to consider electrical, chemical, and thermal properties. The electrical properties of the coating must match that of the component being coated to maintain its performance. Chemical resistance is important for protecting against corrosion and other environmental elements. Lastly, the thermal properties determine how well the coating can withstand extreme temperatures or rapid changes in temperature.
Closing Remarks!
In conclusion, conformal coating is a key process in ensuring the durability and longevity of a range of electronic components. Choosing the right conformal coating material is of paramount importance, and should be decided based on operating conditions, component materials, and the level of protection required.
