Electronics Coating Services


Electronic devices such as power circuit boards (PCBs) and programmable logic controllers (PLCs) are continuously advancing and developing, making them integral in various applications. As electronics are used in more rugged environments, they must be protected from the damages of temperature changes, dirt and UV rays. Otherwise, electronics can malfunction and become unreliable.

Among the different coatings for electronics, conformal coating provides defense against damage and better overall quality for sensors and other power supplies. Diamond-MT is experienced in providing parylene coating for sensors and power supplies, and our services will extend a product's life, improve its efficiency and enhance its reliability.

Benefits of Parylene Coating for PCBs

Parylene coating is one of the best protection options available for circuits, PLCs and other electronics.

It's applied with a chemical vapor deposition (CVD) process that transforms the solid parylene dimer into a gas, allowing deep penetration into the material's surface and small crevices. The layer is uniform and can be applied to almost any material.

Other advantages of conformal coatings for electronics include:

  • No required curing process
  • Nonconducting properties
  • Thin yet protective layer
  • Durable against environmental factors
  • Resistance to moisture and chemicals
  • Comprehensive, pinhole-free coverage
  • Stability in temperature changes

Parylene Coating for Electronics

The protective features of conformal coating are advantageous for many electronic systems.

The following applications benefit from parylene coatings:

  • Wafers
  • Circuits
  • Power supplies
  • I/O and PCI modules
  • Backplanes
  • PCBs and assemblies
  • Microelectromechanical systems (MEMs)
  • Sensors
  • Power converters and supplies
  • PLCs
