Conformal Coating for Advanced PCB Assembly

Protect your PCBs from the elements, including moisture, dust and extreme temperatures with our conformal coating services.

Conformal Coating, a protective & insulative shield for PCBA

What is Conformal Coating?

Conformal coating is a polymeric film that covers, and conforms to, circuit board components and other electronics. Its primary purpose is to protect electronics from environmental elements and corrosion. 

  • FULL CONFORMAL COATING PROCESS

Available for Rapid NPI/Prototype orders through to full batch production

With a range of coating products for PCB assemblies we can move between the various application methods to suit your specific needs.

Highly cost-effective rates are available for both your automated and selective conformal coating requirements however please note we only provide a coating service within turnkey orders and contracts.

Automated & Selective Spraying

For a highly accurate and repeatable conformal coating application choose PVA Selective Coating. Our automated system carries HumiSeal 1B31 acrylic (qualified to MIL-I-46058C) as standard.

Benefits of selective spraying:

  • Fine amounts of coating can be selectively dispensed onto PCB's with high accuracy and optimum results. 
  • Multi axis control allows the coating to sprayed on, around and underneath complex components.
  • No longer a need to mask the keep out areas of the PCB.
  • Allows a price point typically 20% to 30% lower than traditional coating methods.

Manual Spray Booth

Ideal for coating of smaller batch sizes, our manual spray booth operation enables much shorter lead times.

Benefits of Conformal Coatings

  • Ambient Environmental Protection: Conformal coatings shield your electronic components from dirt, moisture, dust, rust, abrasion, chemicals, corrosion, mechanical stress, and vibration, extending your device lifespan and reducing failure rates in diverse settings.
  • EMI/RFI Protection: Conductive conformal coatings act as vital shields, particularly crucial in aerospace, medical, and military sectors.
  • ESD Protection: Coatings prevent damage from electrical arcs between charged objects and sensitive components. The build-up of static charge is mitigated without using board space or extra components, safeguarding more delicate elements.
  • Heat Dissipation: Thermally conductive coatings, increasingly used in LED lighting, power systems, and solar energy, efficiently manage heat, extend equipment life with their protective features.
  • Reduced Maintenance: Conformal coatings reduce maintenance expenses by safeguarding delicate assemblies in harsh conditions. By extending board life and enhancing reliability, they minimise failures, reduce repairs and lower replacement costs.

Board Cleaning & Surface Preparation

Preparing your PCBAs for coating is critical. All products are meticulously pre-treated and cleaned to surpass the standards outlined in IPC CH-65 A and J-STD 001-D before applying the coating.

Two cleaning methods available:

  • Ultrasonic with Vapour Cleaning
  • Aqueous Cleaning

Conformance is checked with our ‘Zero Ion’ contamination testing system to validate the correct level of cleanliness is achieved, prior to the application of any coating materials.
