Rugged Electronics and Conformal Coating

With a rise in global military presence and our reliance on electronics for vital operations, it comes as no shock that the defense, automotive and electronics industries are shifting towards ruggedized electronics. Projections indicate the market could hit approximately $1.5 billion by the close of 2026.

What are Ruggedized Electronics?

While many electronics tout their durability as “tough” or “rugged,” the ultimate benchmark lies in one specification: MIL-STD-810F. This specification outlines rigorous testing methods to ensure devices operate seamlessly in various conditions – from low pressure and high altitudes to extreme temperatures, rain, humidity, shocks, vibrations, accelerations and even exposure to salt fog or fungus.

How Conformal Coatings Help Ruggedize Electronics

Conformal coating serves as a protective, nonconductive dielectric layer applied to printed circuit board assemblies. It shields electronic components from damage caused by contamination, salt spray, moisture, fungus, dust, and corrosion in harsh environments. The choice of conformal coating depends on the product’s intended environment. Acrylics, urethanes, silicones, and Parylene each offer unique benefits.

Uncoated circuit boards exposed to severe environmental conditions may suffer corrosion, mold growth, and current leakage, leading to potential board failure. It is crucial to take additional measures to guarantee the circuitry’s resilience to harsh conditions when designing and constructing rugged computing systems that will endure the product’s lifespan.
