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. 

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:

Manual Spray Booth

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

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:

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.
