CX-PROTECT

CX-PROTECT is the Parylene coating by COAT-X for thin film encapsulation of PCB's,  electronics, sensitive components, and materials.

CX-PROTECT offers maximal protection against oxygen, moisture, and corrosion for the long-term in difficult conditions.

CX-PROTECT is made of Parylene a fully biocompatible material that has been used for more than 50 years for the hermetic packaging of medical devices.

CX-PROTECT

  • is produced by chemical vapor deposition (CVD) under vacuum.
  • can be applied on to metallic, non-metallic materials and even organic materials.
  • is a  truly conformal coating, perfectly matching the object surface,  even within narrow spaces and crevices.
  • is thin, flexible, and very resistant to thermal cycling, not cracking, not shrinking.
  • is ten times more hermetic than epoxy resins allowing large volume and mass reduction of the packaging layer.

 

 

CX-PROTECT
PARYLENE GRADES

CX-PROTECT is available in several Parylene grades

  • Parylene-C: with the lowest permeation rates
  • Parylene-F: for high temperature applications
  • Parylene-N: with the best electrical insulation properties

 

All of them are available in the thickness range of 200 nm to 30 um.

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

CONFORMAL COATING

The unique vapor phase  CVD deposition technology of CX-PROTECT

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

BIOCOMPATIBILITY

CX-PROTECT is made of Parylene, a material that

  • is fully biocompatible and has been used for many decades for medical devices.
  • improves the biocompatibility of materials building a protective barrier layer around the object.
  •  is pure and free of solvent, catalyst, curing agent, or plasticizers.
  • is compatible with most sterilization processes like steam, gamma, or ETO sterilization.
HERMETIC ENCAPSULATION

CX-PROTECT is the best choice for material and device encapsulation thanks to its unique physical and chemical properties. The polymer has indeed exceptionally low gas and water permeation rates.

The water vapor transmission rate of CX-PROTECT is ten times smaller than for epoxy tropicalization resins, enabling a significant thickness reduction for the same barrier properties.

ELECTRIC INSULATION

CX-PROTECT  is an excellent electrical insulator coating with

  • a high breakdown voltage
  • low dissipation factor

 

For electrical insulation, the best results are achieved with the Parylene-N grade.

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 and hundreds of thermal cycles (Parylene-F grade).

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 a special optical or aesthetic application like photonic or watchmaking, Coat-X has developed a specific Parylene grade.

TEMPERATURE STABILITY

CX-PROTECT can be used up to 100°C in the long term while the Parylene-F grade is stable up to 350°C .

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.
