Conformal Coatings & Heat Dissipation Protection
As demand for smaller electronics grows exponentially, your product challenges grow just as much. You need to pack more components into a diminishing space, which can increase your electronics’ susceptibility to overheating due to a reduction in thermal flow.

What’s the Best Coating for Heat Dissipation Protection?
The best coating to facilitate heat dissipation is parylene simply because it’s the thinnest. If you choose a thick coating, it can be a direct cause of overheating, leading to premature failure and decreased reliability. As each component has a maximum operating temperature, it is critical to dissipate heat through methods such as heat sinks.
Traditional protective coatings such as acrylics or epoxies have low thermal conductivities, hundreds to thousands of times lower than ceramics or metals. Therefore, conventional coatings such as silicones create heat barriers that can interfere with the heat transfer path, as they are used in thick layers that can impede heat dissipation.
