Conformal Coating

Active-PCB Solutions offers in-house conformal coating, allowing us to protect your assembled PCBs as an integral part of the manufacturing process before they are dispatched.

For electronics operating in challenging environments, conformal coating provides essential protection against contaminants and environmental stress. By carrying out coating in-house, we maintain full control over application, quality and traceability, while reducing lead times associated with subcontracting.

We provide a range of conformal coating services using proven application techniques, including spray coating and potting, selected to suit the specific requirements of each assembly.

Conformal coating helps protect against moisture and chemical exposure, reduces the effects of vibration, and minimises the risk of current leakage, improving long-term reliability and performance.

Originally developed for military and aerospace applications, conformal coating is now widely used across many industries. Our experience and controlled processes ensure that every coated assembly meets the highest quality standards and is delivered ready for use.

Materials We Use

• Nanocoating:  Ultra-thin and lightweight, waterproof to IPX7/IPX8, flexible and environmentally friendly protection for sensitive components. Does not require time consuming masking making it a low cost option.
• Acrylic (1B31): Versatile, quick-drying protection with good moisture resistance and good dielectric properties. Can be re-worked.
• Urethane (1A33): Excellent chemical and mechanical resistance. Good moisture and humidity resistance.
• These coatings are applied in our in-house conformal coating facility.
• We are also able to provide Silicone and Parylene conformal coating via our trusted partners

What is Conformal Coating and What is it Used For?

Conformal coating is a thin, protective layer which is applied to electronic components to shield them from environmental factors that could compromise their functionality. Originally developed for military and aerospace applications, this technology is now a vital solution across industries – from automotive and medical to industrial and consumer electronics – where equipment is required to withstand tough conditions.

Conformal coating also offers several additional benefits:

• Moisture and Chemical Resistance: Protects electronics from moisture ingress and chemical contamination, extending their operational life.
• Vibration Dampening: Reduces the impact of vibration, minimising potential mechanical stress on sensitive components.
• Reduced Current Leakage: Provides a stable, insulated surface, helping prevent unwanted current leakage that could otherwise lead to malfunction.

Flexible Coating Solutions for Every Application

Through our network of trusted providers, Active-PCB Solutions arranges access to a variety of conformal coating techniques, allowing us to accommodate a broad range of product specifications and environmental requirements.

• Spray Coating: A versatile, efficient option for even coverage that provides effective protection against contaminants and mechanical stress.
• Potting: Potting encloses components fully for maximum protection in extreme conditions, ideal for applications needing robust, long-term stability.

Our team understand that every project’s needs are unique, and our experienced team will consult with you to determine the optimal coating method, materials, and specifications to meet your performance, durability, and environmental requirements.
