Effective EMI and RFI shielding depends on selecting the right materials and applying them with precise process control. Our PVD sputtering technology deposits copper, aluminum, and nickel chrome in configurations optimized for your specific shielding requirements. The most common architecture uses a copper base layer for superior conductivity, protected by an aluminum top layer that prevents oxidation and maintains performance over time.
Copper provides the highest electrical conductivity of common shielding materials, making it ideal for applications requiring maximum EMI protection. However, copper exposed to air oxidizes, degrading its conductive properties. This is why we typically apply an aluminum protective layer over the copper base. Aluminum resists oxidation while maintaining excellent electrical properties. For applications with specific environmental or performance requirements, nickel chrome offers alternative protective properties.
Our PVD sputtering process deposits these materials in precisely controlled thin layers. Unlike thick coatings that add unwanted weight and alter part dimensions, our nanometer-scale films provide necessary electromagnetic interference protection while maintaining design tolerances. This makes PVD ideal for plastic electronic enclosures where designers specify plastic over metal to minimize weight and reduce costs. The coating conforms to complex geometries and reaches hard-to-access areas where electromagnetic protection is most critical.
Electromagnetic interference shielding for government, defense, medical, and aerospace applications demands more than technical performance. It requires documented compliance with industry regulations, military specifications, and quality standards that protect both manufacturers and end users. Vergason Technology maintains the certifications and registrations that enable us to support your most demanding compliance requirements.
Our ISO 9001:2015 certification ensures consistent, repeatable coating processes across every production run.

Throughout the engagement, you work with a dedicated team that understands your application and can answer technical questions that arise during development or production.
Electromagnetic interference occurs when electrical circuits experience disruption from external electromagnetic sources. Both natural and man-made electromagnetic fields create EMI that can affect any electronic device. The consequences range from minor performance degradation to catastrophic system failures, making professional electromagnetic shielding essential for reliable electronics in critical applications.
Medical equipment affected by RFI interference can provide incorrect readings or fail during critical moments. Military communication systems disrupted by electromagnetic interference compromise mission effectiveness. Industrial process control systems experiencing EMI can cause production disruptions or safety incidents. The cost of field failures, whether measured in warranty claims, liability exposure, or mission failure, always exceeds the investment in proper EMI and RFI protection.
Professional shielding coating services provide electromagnetic protection without the capital investment, process development time, and technical expertise required for in-house capabilities. Many companies lack the specialized PVD equipment and process knowledge needed for effective shielding. Outsourcing to an experienced provider like Vergason Technology gives you access to proven processes, regulatory compliance, and technical support that would take years to develop internally.
Understanding how electromagnetic interference shielding works helps engineering teams make informed decisions about coating specifications and material selection. The fundamental principle involves blocking offending EMI before it reaches sensitive electronics inside the enclosure. Highly conductive materials like copper and aluminum absorb the electric field in the EMI, converting electromagnetic energy into kinetic energy within the metallic coating.
Our PVD sputtering process deposits these conductive metals in precisely controlled thin layers. The sputtering technique uses energized plasma to eject atoms from a target material, which then deposit onto your parts in a highly controlled vacuum environment. This atomic-level deposition creates uniform, dense coatings that conform to complex geometries and reach areas that other coating methods cannot access effectively.
The typical EMI shielding architecture starts with copper for its superior electrical conductivity. Copper's low electrical resistance makes it the most effective common material for blocking electromagnetic interference. However, copper oxidizes when exposed to air, forming copper oxide that significantly reduces conductivity over time. To prevent this degradation, we apply an aluminum protective layer over the copper base. Aluminum naturally forms a thin, stable oxide layer that actually protects the underlying metal while maintaining excellent conductive properties.
This multi-layer approach provides both immediate shielding effectiveness and long-term performance stability. The copper delivers maximum EMI protection, while the aluminum ensures that protection persists throughout the product's service life. For applications with specific environmental exposures or unique performance requirements, nickel chrome coatings offer alternative protective properties. Our engineering team can recommend the optimal material combination based on your operating conditions and shielding specifications.
