What is die-cut EMI/RFI Shielding?
Die-cut EMI/RFI (Electromagnetic Interference/Radio Frequency Interference) shielding refers to the process of converting raw conductive materials, like nickel-loaded pressure-sensitive adhesives, metalized PETs, and copper foils, into usable custom components that mitigate and deflect disruptive EMI & RFI. More specifically, die-cut EMI/RFI shielding:
- Reflects electromagnetic and radio frequency energy
- Absorbs and dissipates interference to prevent crosstalk
- Provides a controlled grounding path
- Eliminates gaps and leakage paths for EMI/RFI through proper sealing
Precision die-cut EMI/RFI shields from JBC also play a crucial role in achieving EMC compliance, an important metric that ensures a product/system functions properly without generating or becoming susceptible to interference.
The Role of a Converter
A skilled converting partner like JBC Technologies plays the important role of transforming these raw EMI/RFI shielding materials into functional components that manufacturers and OEMs can actually use and integrate into their assemblies. JBC adds value through:
Tight Tolerance Precision to ensure precise seals and prevent EMI/RFI leakage
Vertically Integrated Converting to integrate multiple material layers into a single EMI/RFI component
Optimized Part Presentation for automation-friendly integration and handling

Ask an Engineer: EMI/RFI Shielding Q&A
Yes, JBC Technologies sources many EMI/RFI shielding materials that meet UL94 V-0 flame retardancy requirements. JBC is vendor agnostic, meaning we work with a diverse range of material manufacturers to help you source the material that's actually right for you.
Yes, JBC kiss-cutting components are a core capability of our vertically integrated die-cutting presses. Kiss-cutting is an important part of presentation consideration for components like EMI/RFI gaskets, which require easy peel-and-stick placement later in the production process.
It's important to discuss your post-processing needs with your converting partner so they can optimize the presentation of your custom die-cut components for easy integration into your supply chain.
Yes, custom die-cut EMI/RFI shielding components are an assembly-friendly way to help meet proper Electromagnetic Compatibility (EMC) Compliance by containing internal interference or shielding sensitive components from external noise.
JBC Technologies sources EMI/RFI shielding from a wide range of industry-leading material manufacturers. We take on a vendor-agnostic approach to material sourcing, meaning we work with suppliers across the board to help you source the best material for your die-cut EMI/RFI component.
JBC is proud to be a 3M Preferred Converter, a Rogers Major Converter, and a part of the Avery Dennison ADVantage Converter system.
The terms EMI & RFI are often used interchangeably, but they do refer to two slightly different technical challenges. Essentially, RFI is a subset of EMI, referring to a specific type of Electromagnetic Interference. Here's the breakdown:
EMI (Electromagnetic Interference) - This is the umbrella term for any electrical disturbance. This includes low-frequency noise from motors or power lines.
RFI (Radio Frequency Interference) - This is a specific type of EMI, referring to high-frequency signals like Wi-Fi, cellular, or Bluetooth.
How does this affect shielding choices? Solving low-frequency interference typically requires magnetic shielding, while high-frequency RFI requires more specialized conductive materials, like copper-faced films, metal-filled adhesive tapes, and foil-faced foams.
For high-volume production lines where assembly efficiency is a critical throughput consideration, JBC leverages our vertically integrated converting capabilities and process engineering expertise to optimize the part presentation of each component for easy integration into different assembly lines. JBC's part presentation includes:
- Kiss-cutting for sheet, roll, or individual part delivery
- Pull-tabs, extended liners, and easy-release liners for easy peel-and-stick application of adhesive-backed EMI/RFI components
- Custom packaging and automation-ready kitting
Yes, multi-layer laminating is one of JBC Technologies' core capabilities as a vertically integrated converter.
