PCB conformal coating is the process of applying a polymer film with a thickness of 25 to 75 µm (typically 50 µm) to protect PCB components. This coating helps protect electronic components from a variety of environmental hazards, debris and harsh chemicals. East India Technologies offers a wide variety of conformal coatings for printed circuit boards. Our services are focused on all types of coating such as medium, low or high-volume conformal coating requirements for a variety of printed circuit boards.
Types of Conformal Coating for Printed Circuit Boards
EITPL offers a wide range of conformal coating services for printed circuit boards using a variety of coating types. Coatings are applied by brush, spray or dip.
Acrylic Resin: Acrylics are generally a type of solvent-soluble preformed acrylic polymer. Acrylic coatings are easily soluble in many organic solvents, making repair work easier. Our acrylic coating offers excellent mould and moisture resistance, dries quickly and has a long shelf life.
- The coating provides an excellent smooth and crystal-clear surface.
- The acrylic coating meets Mil-I-46058C and IPC-CC-830 specifications.
Parylene: Parylene is a polymer-based compound composed of linear and crystalline polymers. The coating is applied in a vacuum environment and spreads over the material in gaseous form with the formation of a transparent polymer film.
- The coating can penetrate gaps up to 0.01 mm wide.
- Its excellent thermal stability, the coating can be used in a temperature range of -200 ºC to 150 ºC.
- Parylene liners are USP Class VI plastic compliant and FDA cleared. The coating is listed in MIL-I-46058C / IPC-cc-830B (as class XY). Parylene coating meets NBC AR70 / AFR80-38 / Navinst 3400.2 requirements.
Polyurethane: Polyurethane coatings provide improved chemical resistance and excellent dielectric properties. We offer one-component, two-component, UV-curable and water-based polyurethane coatings.
- Polyurethane coating is Mil-I-46058C and IPC-CC-830 approved.
- This coating provides excellent grip when working in all weather conditions and has high dielectric properties.
- These coatings are very resistant to humidity.
Epoxy: The epoxy resin coating is a 2-part type with excellent resistance to abrasion, chemicals and humidity.
- The coating works at temperatures up to 150°C.
- The epoxy coating provides a hard coating on the surface. This provides excellent wear and chemical resistance.
Silicone: Silicone resins are soft, transparent and flexible coatings with excellent corrosion and chemical resistance. Silicone coatings have a low dissipation factor and are suitable for high impedance circuits.
- The silicone coating operates over a temperature range of 55°C to 200°C.
- This coating has excellent heat, UV and humidity resistance, which helps protect small parts.
- This coating has excellent light transmission properties, making it ideal for solar energy applications.
- This coating complies with MIL-I-46058C and IPC-CC-830 standards.
