custom EMI shielding can

EMI shielding cans, also known as RF cans or shield cans, are metallic enclosures mounted on printed circuit boards (PCBs). They are specifically designed to shield sensitive electronic components from unwanted electromagnetic fields. These cans not only prevent external EMI from interfering with device performance, but they also stop internal emissions from affecting nearby devices.

Key Functions:

• EMI/RFI suppression: Reduces electromagnetic and radio frequency interference.

• Signal integrity: Ensures stable signal transmission in high-frequency circuits.

• Component protection: Shields delicate components from environmental hazards like static, noise, and electrical discharge.

• Regulatory compliance: Helps manufacturers meet industry standards like FCC, CE, and ISO.

Applications of EMI Shielding Cans

EMI shielding cans are widely used across various industries. With the increasing complexity and miniaturization of electronics, effective shielding is more critical than ever.

Common Industries We Serve:

• Consumer Electronics: Smartphones, laptops, gaming consoles, and smart home devices.

• Automotive: ECUs, radar systems, infotainment systems, and ADAS modules.

• Telecommunications: Routers, 5G equipment, and RF modules.

• Medical Devices: Diagnostic instruments, monitors, and portable medical equipment.

• Industrial Controls: Robotics, automation equipment, and high-voltage systems.

• Aerospace & Defense: Secure communication systems and navigation tools.

Types of EMI Shielding Cans We Offer

✅ Soldered EMI Shielding Cans

Designed to be permanently attached to PCBs via reflow or wave soldering. These are ideal for high-vibration or high-volume production environments.

✅ Clip-on or Snap-on Cans

Allow for tool-free installation and easy removal during repair or testing. We provide matching PCB shield clips for a secure fit.

✅ Multicavity Shields

Perfect for shielding multiple components or ICs in a compact area. These help reduce cross-talk and increase signal integrity in dense PCBs.

✅ Formed and Drawn Shielding Covers

Produced through deep drawing processes, these are seamless cans with improved EMI performance and durability.

Surface Finishes and Coatings

At TMN, we understand that the right finish not only enhances shielding performance but also improves corrosion resistance and solderability.

Available Coatings:

• Tin plating

• Nickel plating

• Silver plating

• Gold plating (for high-performance applications)

• Chemical conversion coatings (RoHS-compliant)

We also offer anti-oxidation treatments for long-term performance in challenging environments.

Prototyping and Mass Production

Whether you're in the design phase or ready for mass production, TMN Metal Parts can support your project at every stage.

• Rapid prototyping: Short lead times with laser cut or CNC samples

• Small and medium batches: Flexible production capacity

• High-volume production: Automated stamping lines for millions of units per year

Our engineering team is available to help optimize your design for manufacturability (DFM) and cost-effectiveness.
