There was a time when only circuit boards used in mission-critical applications were coated for protection. They were those with the need for stability and durability that went beyond financial considerations or minor inconveniences. Today, the demand for protection and reliability is ubiquitous in commercial and consumer applications across a multitude of industries, including automotive, military, aerospace, IoT, consumer electronics, industrial and medical.
Of the available conformal coating technologies, Parylene can provide the best protective barrier necessary from the environment and corrosion. Parylene conformal coatings are uniquely applied by a chemical vapor deposition process to ensure a consistent coating application. Perfecting the application of Parylene coatings requires process, expertise, chemistry and capital equipment — the latter being critical to repeatable and scalable processes. Nanocoatings company HZO searched worldwide for applicable coating equipment up to that task. Not finding what they needed, they built it. They now have the largest Parylene coating chamber in the industry.
