custom shielding clips & shielding cans

EMI and RFI can cause malfunctions in electronic devices, leading to degraded performance or even complete failure. These forms of interference are particularly problematic in consumer electronics, automotive electronics, telecommunications, medical devices, and aerospace systems. Shielding clips and shielding cans offer a physical barrier that prevents electromagnetic noise from passing in or out of a device’s circuitry.

What Are Shielding Clips?

Shielding clips, also known as grounding clips or retention clips, are small, spring-like metal components designed to hold a shielding can securely in place over sensitive components on a PCB (printed circuit board). These clips allow for the easy installation and removal of shielding cans, making them ideal for applications that require frequent maintenance, testing, or updates.

Key Features of TMN Shielding Clips:

• High Precision Manufacturing: TMN utilizes high-speed stamping and CNC machinery to ensure each clip has consistent shape and dimensions.

• Excellent Conductivity: Made from materials like stainless steel, phosphor bronze, or beryllium copper, TMN’s clips maintain high conductivity for effective EMI containment.

• Corrosion Resistance: TMN applies surface treatments such as tin or nickel plating to ensure long-term durability.

• Custom Designs Available: TMN supports custom clip designs tailored to specific PCB layouts or unique customer requirements.

Applications of Shielding Clips:

• Mobile phones and tablets

• Automotive control units

• IoT devices

• Medical diagnostic equipment

• Communication routers and servers

What Are Shielding Cans?

Shielding cans, also called EMI shielding enclosures or metal shields, are small box-like structures mounted directly onto the PCB. They enclose a specific circuit or set of components to prevent EMI emissions and protect against external RFI. TMN Metal Parts Fabrications Factory produces shielding cans using advanced stamping and bending technologies, delivering both standard and custom sizes.

Key Benefits of TMN Shielding Cans:

• Effective Shielding: TMN shielding cans are designed with precise tolerances to maximize EMI/RFI attenuation.
