PCB Conformal Coating Services
PCB conformal coating is a protective layer of polymer or resin applied to printed circuit boards (PCBs) to protect their components and circuitry from environmental factors like moisture, dust, chemicals, and extreme temperatures. It enhances device reliability and longevity by preventing corrosion, electrical shorts, and insulation failures, especially in harsh environments. It also provides mechanical protection against vibration and shock.

Key Benefits of PCB Conformal Coating for Enhanced Reliability
PROTECTION AGAINST ENVIRONMENTAL CONTAMINANTS
PCB conformal coatings are crucial for automotive electronics due to their ability to prevent harsh environments from damaging circuits and dust, dirt, and small particles from shorting out circuits, especially in harsh road conditions and de-icing salts.
ELECTRICAL INSULATION AND PREVENTING SHORT CIRCUITS
A good conformal coating provides electrical insulation, preventing short circuits caused by bridging between conductive paths. This is crucial in high-voltage applications or humid environments, as it prevents water from conducting electricity, ensuring device safety.
MECHANICAL PROTECTION AND VIBRATION RESISTANCE
Conformal coatings provide physical toughness to delicate components, shielding them from constant vibration or shocks. They act as extra padding, reducing the risk of physical damage from bumps or movement, thus extending the lifespan of PCBs.
THERMAL MANAGEMENT ASSISTANCE
Conformal coatings, while not their primary function, can aid in thermal management by transferring heat from sensitive components, thereby keeping PCB cooler, resulting in longer lifespan and improved performance in devices generating high heat.
// Most Frequent Questions
PCB Conformal Coating FAQ
Conformal coating is a thin protective film applied to printed circuit boards (PCBs) to safeguard against moisture, dust, chemicals, vibration, and temperature variations. It helps extend the lifespan and reliability of electronic assemblies.
It prevents corrosion, electrical leakage, and short circuits caused by environmental exposure. This is particularly important in industries such as automotive, aerospace, medical, and industrial electronics.
EMS, Inc. provides acrylic (AR), silicone (SR), polyurethane (UR), and epoxy (ER) conformal coating services. Each type offers different levels of protection, flexibility, and chemical resistance depending on application needs.
We use selective robotic coating, brushing, and spraying.
With our PVA 6000 conformal coating system, your PCBs receive precise and consistent protection against moisture, dust, and harsh environments, ensuring greater reliability, extended product life, and peace of mind for your end users.
Coating is typically applied after testing, but if needed, masking or selective application can ensure test points remain accessible.
Yes, areas such as connectors, sockets, and certain components must be masked to prevent coating coverage and ensure functionality.
Most coatings range from 25 to 75 microns.
Automotive, aerospace, defense, medical, consumer electronics, marine, industrial equipment, and renewable energy industries commonly use conformal coating.
The choice depends on your operating environment, performance requirements, rework needs, and regulatory standards. We can help recommend the right solution.
