Parylene Coating Services

For more than 35 years, ADI has provided conformal coatings for a wide variety of circuit boards and components. This system maintains integrity by providing protection from moisture, salt, chemicals, and temperature changes. Recently, ADI added Parylene Coating Services to its EMT division in Bangalore, India. This coating process is a unique coating technology. Parylene Coating’s benefits emanate from the unique way in which it gets applied. This leads to the best coverage of any conformal coating compound with the best uniformity. Furthermore, the unique way in which Parylene coats items allows it to be deposited at thicknesses ranging from 0.2 to 100 μm per run

The deposition technique of polymers takes place at the molecular level and consists of three basic steps.
1. The first step is vaporizing the solid dimer. The dimer is heated to a temperature of 160°C and is dissipated into gas.
2. The gas is then pyrolyzed (thermos chemical cleavage of organic compounds) to cleave the dimer into its monomeric form.
3. The monomer gas is deposited in the deposition chamber at room temperatures as a transparent polymer film.
The desired coating can vary depending on the application and be from 0.2 to 100 μm per run.

Applications for Parylene coating –
Here is a sample list of applications. If you have not found your desired application, our team will be happy to advise you. Compliant coating of electronic components for harsh environmental conditions (complies with “MIL-I-46058C, Type XY”)

  • Circuit Card Assemblies
  • Dielectric coating such as cores, coils, magnets
  • Barrier layers for example filters, membranes, valves
  • Microwave components, electrical engineering
  • Sensors in harsh environment
  • Corrosion protection for metallic surfaces
  • Reinforcement of microstructures
  • Abrasion protection
  • Protection of plastic, rubber and other materials against environmental influences
  • Transparent protection for LEDs, for example, in lighting systems for aircraft, vehicles, light panels, etc. >
  • Hydrophobic coating such as biomedical tubing, catheters, etc. → reduces friction (for example, catheter guidewires)
