Home > Blog > EMI Shielding > Copper Shielding Tape: An Innovative Solution to Electromagnetic Interference

Copper shielding tape is a type of EMI shielding solution that can be applied to enclosures, PCBs and cables. It offers excellent performance as compared to other types of shielding tapes available on the market. Its ability to protect electronics from EMI makes it an invaluable tool for various industries where high-level interference needs to be neutralized or avoided. Overall, copper shielding tape is one of the most popular types of shielding tape on the market. But what accounts for their wide popularity? This post lists some of the reasons why copper shielding tape is so popular along with discussing how it can benefit various industries.

Why Prefer Copper Shielding Tape?

There are several reasons why copper is preferred to other materials for use in EMI shielding. Copper is an excellent conductor of electricity and has a very low resistivity, which means that it can effectively block electromagnetic fields. Copper is also very ductile, so it can be easily formed into the desired shape. Additionally, copper resists corrosion, making it a durable material for use in EMI shielding. The following points also substantiate your decision on investing in copper shielding tape.

  • Cost-Effective Shielding: Copper shielding tape is a cost-effective shield solution for combating electromagnetic interference (EMI) in devices and electrical equipment. This tape features a conductive adhesive backed by a flexible material that is easily applied to surfaces needing EMI shielding. With this application, the adhesive forms an effective conductive path capable of dissipating surrounding EM energy.
  • Static Charge Drainage: Copper tapes provide an easy way to minimize static build-up on vulnerable devices and components, such as CRTs and computer peripherals. The strong adhesive bond provides a dependable ground connection in order to protect against potentially dangerous static charges.
  • Mechanical Protection: Copper tape is an excellent way to mechanically protect the wires and electrical components of a circuit. It ensures proper insulation and prevents any accidental contact between wires that could result in device failure. Applications like pressure sensors benefit greatly from this kind of protection, making copper tape an extremely useful product for electronic system design.

Industries Served

Industries that benefit from copper shielding tape include:

  • Aerospace: Copper shielding tape is used to protect aircraft components from electromagnetic interference. This type of interference can come from a variety of sources, including aircraft, radar, among others. The shielding tape ensures that aircraft components are not damaged by this type of interference. This type of tape is often used to repair electrical wiring and other components that have been damaged by EMI.
  • Telecommunications: The tape is available in a variety of widths and thicknesses, making it versatile for a range of applications in the telecommunication industry. It is used to shield against electrical shocks/static discharge and also cable assembly and wiring. Copper shielding tape is often used to wrap around the outside of coaxial cables. The tape protects the inner conductor from EMI and maintains the integrity of the signal.
  • Medical: Copper shielding tape is used in various medical applications, including MRI machines, X-ray machines, and CT scans. It is also used in medical devices such as pacemakers and defibrillators.
  • Automotive: Some of the most common uses for copper shielding tape in the automotive industry include protecting electrical wiring, shielding delicate parts from electromagnetic interference, and sealing openings in vehicle body panels.

Overall, copper shielding tape is widely used in a variety of EMI shielding applications due to its ease of use and highly conductive nature. This tape is available in a variety of widths and thicknesses to suit the needs of your application and can be easily applied to flat or curved surfaces as per the needs of your applications. Although used for a variety of EMI applications, the copper shielding tapes may not work effectively for board level shielding. This is where SnapShot ™ EMI shields can make a difference. These are revolutionary, multi-level shields that can easily solve the challenges of copper shielding tapes. The multi-level shields have been successfully used in the most demanding and challenging rugged applications, such as military handheld radios, military drones, military avionics, military weapon systems, and industrial handheld computers and scanners, etc. Contact us today to discuss to discuss your EMI shielding requirements.
