Custom EMI & RFI Shielding

In today’s increasingly connected world, electronic devices emit and receive a wide spectrum of electromagnetic signals. While this interconnectivity enhances functionality, it also increases the risk of interference. EMI and RFI can cause disruptions, degradation, or even complete failure in electronic systems. This interference can originate from internal components, external sources, or a combination of both.

Industries such as aerospace, defense, telecommunications, automotive, consumer electronics, and medical technology rely heavily on effective EMI/RFI shielding to:

• Prevent signal interference

• Ensure device functionality and safety

• Achieve compliance with regulatory standards (e.g., FCC, CE, MIL-STD)

• Protect sensitive data and intellectual property

• Enhance the lifespan of critical components
