Specialty Coating Systems highlights the advantages of using Parylene conformal coatings to enhance the ruggedization of products operating in extreme environments.
Ruggedized equipment is engineered to function dependably in the most demanding environments. Whether it’s embedded systems for defense applications, mobile computers for specialized research, or aerospace components, these products are constructed to endure high moisture levels, extreme dryness, severe temperatures, heavy vibrations, strong wind forces, and even vacuum conditions. Both their external enclosures and internal components are reinforced to meet strict durability standards.
Parylene Coatings in Ruggedization
There are multiple techniques used by manufacturers to achieve ruggedization, but Parylene conformal coatings are particularly notable for their advanced performance. These coatings offer strong resistance to physical shocks, continuous vibrations, and extreme environmental conditions. They shield against moisture, heat, dust, harmful chemicals, and other contaminants. With excellent dielectric strength and the ability to be applied in ultra-thin films, Parylene is well-suited for applications across a broad range of sectors.
Applications of Ruggedized Technologies
In military and industrial settings, keyboards and keypads often utilize Parylene coatings to protect their Printed Circuit Boards (PCBs) and other essential parts. These coatings allow the equipment to withstand rapid acceleration, pressure changes, temperature and humidity shifts, impacts, and vibration over prolonged use. They also comply with MIL-STD-461 requirements for electromagnetic interference shielding.
Rugged smartphones, tablets, and similar mobile devices incorporate Parylene coatings to defend sensitive electronics against dust, water, shocks, drops, and temperature extremes. This enables consistent connectivity and reliable performance in adverse conditions. Other ruggedized items like cameras, connectors, and bonding assemblies also benefit from this protective layer.
In the automotive field, sensors, control systems, and seals are often exposed to intense operational environments. Ruggedization helps enhance their reliability by reducing the likelihood of failure from thermal fluctuations or exposure to corrosive substances. Parylene plays a vital role in preserving these components, supporting reliable systems for GPS, WiFi/Bluetooth, and vehicle diagnostics.
The aerospace and commercial sectors also rely on Parylene coatings. These coatings help prevent unwanted adhesion on silicon-based materials, support dependable fiber optic communication, and shield transceivers and testing equipment from environmental threats. Applications in these industries often require compliance with rigorous standards such as MIL-STD-883, MIL-STD-810, and ARINC 801-806, all supported by Parylene.
Conclusion
As ruggedized systems become more critical across various industries, the need for products that deliver consistent performance in extreme conditions continues to grow. Parylene conformal coatings provide an effective method for meeting these demands, enhancing the durability, reliability, and operational lifespan of ruggedized devices and systems.
