Choosing the right coating solution is crucial for the exact protection you need. HZO's selection of material science blends originates from the HZO Spectrum of ProtectionTM – a broad array of materials that encompasses Parylene, and plasma-based nano coatings, among other solutions.
Parylene Conformal Coatings
​
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 amongst OEMs.

Plasma-based Nanocoatings
​
Plasma-based nanocoatings are an ideal choice if you want to protect your electronics from splashes and spills. However, you may want to consider a Parylene coating for complete waterproofing capabilities or to withstand the harshest, most corrosive environments commonly found in industrial settings.
Plasma-based nanocoatings, applied with plasma-enhanced CVD, at micron-thin layers are marginally conformal. Plasma-enhanced CVD works by flowing a precursor gas into the plasma chamber. The gases ionize in an electric field and become plasma, with those ionized materials bonding chemically to the product’s surface and each other to create a barrier. The resulting thickness can range from several nanometers to several micrometers.

Atomic Layer Deposition (ALD)
​
Atomic layer deposition used to produce conformal coating is related to chemical vapor deposition but occurs on an atomic scale, as the name suggests. One material is heated into a vapor and allowed into the coating chamber, then removed after a uniform film is created so a different substance can be introduced next. Once two or more materials collect on the component, their reactions produce new protective properties and effects.
With the atomic layer deposition (ALD) process, it’s possible to use thin metal and ceramic coatings for your PCBAs.
