SIMPLIFY RELIABILITY

Parylene 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 challenging 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.

What are the Benefits of Parylene?

Cost Reduction

Reduce reliability-related repairs resulting from corrosion or water damage, refunds, warranty claims, and service calls

Minimize product recalls and product reliability

Lower total cost of ownership with long-lasting, durable protection

Functionality

Easily meet waterproof, corrosion protection, dielectric, thermal, and chemical resistance requirements

Help with lightweighting products for improved fuel and energy efficiency, as well as overall mechanical stability, for aerospace, automotive, billboard, and large display applications

Used as an anti-reflective (AR) coating for sensors

Excellent biocompatibility and biostability

Helps products meet ASTM, FDA, IPC, ISO, JEDEC, MIL, UL, and other industry standards

Risk Mitigation

Reduce risk of corrosion damage from exposure to humid, salty, sulfurous, and other harsh environments

Reduce risk of damage due to solvents and water exposure

Reduce risk of electrical failures due to foreign object debris (FOD) and metal whiskers

Reduce risk of dendrite formation / electrochemical migration (ECM)

Minimize water absorption in humid environments

Improved Reliability

Imparts low stress to solder joints, especially during thermal cycling

Has very low levels of outgassing, which is critical for satellite and extreme remote sensing applications

Low history of service required in high-reliability applications, especially in aerospace, defense, and medical device applications

Parylene Properties

Parylene films are notable for their material properties, including excellent dielectric performance, good abrasion resistance, outstanding chemical resistance, and low thermal expansion.

Parylene’s chemical vapor deposition (CVD) process results in pinhole-free coatings with consistent thickness and true conformality.

There are no initiators or catalysts in the polymerization process, so the coating is free from trace ionic impurities, and is also REACH, Restriction of Hazardous Substances (RoHS) Directive, PFOA/PFOS-free, and California (CA) Proposition 65 compliant.

The HZO Difference

Parylene Coatings Properties Include: 
  • Insoluble to common chemicals and conditions
  • Superior barriers to moisture and chemicals
  • Complete conformality on all exposed surfaces, corners, and edges
  • Defect-free
  • Free of solvents, residues, and catalysts
  • Dry film lubricity
  • High Dielectric Strength
  • No outgassing
  • No curing
  • No thermal stress
  • Optically clear and colorless

Parylene comes in several varieties, each with unique properties, ensuring a Parylene for virtually any application. Parylene types include:

Parylene F-VT-4 – Highly crystalline, excellent dielectric, very low friction coefficient, ideal for applications that entail exposure to elevated temperatures

Parylene N – Excellent dielectric, halogen-free, suitable for applications where sustainability is a priority

Parylene C – Most widely used, lowest permeability to moisture and gas, ideal for components exposed to corrosive substances

Advantages of Various Parylene Types

ATTRIBUTES PARYLENE C PARYLENE N PARYLENE F (VT-4) Parylene F (AT-4)
High levels of subversion protection - IPX8+, depending also on device design.
Uniform, pinhole free coating.
High barrier protection against corrosive chemicals and gases while providing low permeability moisture. Best barrier when compared to the other Parylene types.
Optically transparent and can be used to coat optical elements.
Bistable, biocompatible, environmentally friendly — no VOCs, no solvents.
No initiators or catalysts in polymerization process, coating is pure and free from trace ionic impurities.
REACH, RoHS, PFOA/PFOS-free and CA Prop 65 compliant.
Room temperature formation makes the coatings effectively stress-free.
Low dielectric constant with good high frequency properties, good dielectric strength and high bulk and surface resistance.
High tensile strength.
No cure time.
Vibration resistant.
No pooling of coating in low areas.
Halogen free.
Free from bromine and chlorine halogens; contains fluorine.
Higher resistance to heat than Parylene C and N.
Highest temperature and UV resistant Parylene.
