Parylene thin film encapsulation of flexible electronics by Coat-X

Produced by chemical vapor deposition (CVD) under vacuum.

Applied to metallic, non-metallic and even organic materials.

Truly conformal, perfectly covering complex shapes

Penetrating even within narrow spaces and crevices.

Thin, flexible, and very resistant to thermal cycling, not cracking, not shrinking.

Ten times more hermetic than epoxy resins allowing large volume and mass reduction.

AVAILABLE IN VARIOUS GRADES

 

CX-PROTECT is available in several Parylene grades

  • Parylene-N: non-modified molecule with the best electrical insulation properties
  • Parylene-C: Chlorine-modified with the lowest permeation rates
  • Parylene-F: Fluorine-modified with the best temperature stability

 

Any grade available in the thickness range of 200 nm to 30 um.

The Parylene grade must be carefully selected, depending on operating and process conditions. 

TRULY CONFORMAL COATING

 

The unique vapor phase  CVD deposition technology of CX-PROTECT

  • Creates truly 3D conformal coatings. Penetrates even small cavities and crevices.
  • Is a non line-of-sight process, without shadowing effect,  without penetration limitation due to surface tension, without remaining porosity and voids.
  • Is free of cracks, stresses and pinholes.
  • Is smooth and conform to substrate roughness.

A BIOCOMPATIBLE MATERIAL

 

CX-PROTECT is made of Parylene, a polymer that

  • is fully biocompatible and has been used for many decades for medical devices, has been FDA-approved, meeting biocompatibility requirements of USP Class VI and ISO 10993.
  • improves the biocompatibility of materials building a protective barrier layer around them.
  •  is pure and free of solvent, catalyst, curing agent, or plasticizers.
  • is compatible with most sterilization processes like steam, gamma, or ETO sterilization.
BUILDING HERMETIC ENCAPSULATION

 

CX-PROTECT build a barrier against contaminants, chemicals, gases and moisture, thanks to exceptionally low gas and water vapor permeation rates, ten times smaller than epoxy, it provides a protection at a fraction of the mass of tropicalization sprays.

ELECTRIC INSULATION

 

CX-PROTECT  is an excellent electrical insulator coating with

  • a high breakdown voltage as high as 7000V for 25 um film
  • low dissipation factor as low as 0.0002 for Parylene N grade
  • high volume resistivity
  • properties remaining constant over temperature changes.

CX-PROTECT is the ideal thin film electrical insulation for narrow, or space-limited designs.

 

 

 

COMPATIBILITY WITH VARIOUS TYPES OF PCB

 

CX-PROTECT is  compatible with rigid and flexible PCB and PCBA (glass fibers, polyimides) with or without solder masks.

CX-PROTECT on PCB resists to the high temperature solder reflow process or hundreds of thermal cycles (Parylene-F grade) without delamination.

EXCELLENT LIGHT TRANSMISSION FOR OPTICAL APPLICATIONS

 

CX-PROTECT is highly transparent in the complete visible range and thus extremely useful for optical applications. The refraction index lies between 1.5 to 1.6.

For special optical or aesthetic applications like photonic or watchmaking, COAT-X has developed the ParyCLEAR grade.

TEMPERATURE STABILITY

 

CX-PROTECT  is stable up to 350°C  (Parylene-F grade) without significant loss of properties. Inert or oxygen-free environment allows even application at higher temperatures and longer time.

SOLVENT AND ACID STABILITY

 

CX-PROTECT is an excellent barrier against aggressive chemicals it resists most solvents, acids, and bases used in industry with no solubility in aggressive medias.

COEFFICIENT OF FRICTION

 

CX-PROTECT can be used as a dry lubricant or to reduce the tackiness of polymers thanks to its low static and dynamic coefficient of friction .

MECHANICAL PROPERTIES

 

CX-PROTECT is made of Parylene a of high performance semi-crystalline thermoplastic polymers with excellent mechanical properties.

COATING SERVICE

 

COAT-X provides coating service for CX-PROTECT protective coatings for medical devices, electronic PCB's,  industrial components, jewelry pieces and watches.

Last generation plasma-enhanced chemical vapour deposition (PE-CVD) machines are available for the quick handling purchase orders.
