Thin Film Coating Services

Product design is often a struggle to balance multiple goals that can seem conflicting. Reducing time to market, staying within budget, and aligning your products’ form factors with miniaturization trends are vital concerns. Achieving these goals can be a challenge when you must also ruggedize your products to the point that they can operate reliably in harsh conditions. Conformal coatings, particularly Parylene films, applied to circuitry and electronic components can be a solution for protection from harsh environments.

Parylene Conformal Coatings

HZO Guardian™ Series

Parylene is an organic and biocompatible compound that delivers superior protection against all forms of environmental risks. It’s uniquely inert and highly effective at reaching small recesses because of how it forms.

Parylene coating applications take place inside a chemical vapor deposition (CVD) vacuum system, where the products wait inside a room-temperature chamber. After the raw material heats up from a solid to a gas — so much so that the Parylene splits into monomers — the vapors travel to a coating chamber where the molecules cool and polymerize on everything in the chamber. Over time, this builds layers of a polymerized film, microns-thin, and pinhole-free.

Parylene conformal coatings are excellent for applications found in the aerospace, defense, medical device, and industrial products industries. This type of versatility makes it a top choice among OEMs.
