What is EMI Shielding
EMI shielding means electromagnetic interference shielding. EMI is caused by the wrong delivery of electromagnetic capabilities and can interfere with the stable running of electronic devices. EMI shielding is used to establish a shielding barrier between the interference source and the device being interfered with, preventing the interference signal from reaching the target electronic device.
The Benefits of EMI Shielding
Protect Electronic Components: The primary benefit of GALLOP INNOTEK EMI shielding is to protect electronic components. EMI shielding can reduce, or even remove, the electromagnetic interference. Finall,y to ensure the electronic equipment runs stably.
In addition, GALLOP INNOTEK EMI shielding can prevent signal weakening and reduce the damage risk to electronic components, thereby extending the service life of sensitive electronic components.
Improve Performance and Efficiency: GALLOP INNOTEK EMI shielding can ensure a high-quality signal. This means that the data delivery in electronic equipment will be accurate, thereby improving the performance of the equipment.
The electronic noise can reduce sensor accuracy. EMI shielding can also reduce the electronic noise and improve efficiency.
Reduce Cost: EMI may cause a little problem with your electronic equipment. However, if you do not implement EMI shielding, the minor issue will cause the electronic equipment to malfunction over time. Then the maintenance and repair costs are unavoidable.
GALLOP INNOTEK EMI shielding can help you prevent the damage risk of electronic equipment. Additionally, it can prevent equipment downtime and ensure optimal running efficiency. Generally speaking, EMI shielding can help you reduce the cost of your equipment.

The Importance of EMI Shielding
If there is no EMI shielding, EMI will produce noise in electronic circuits, interfering with the normal operation of digital systems. Finally, the digital data will be compromised and lead to errors in your communication protocols, data processing, and storage.
If you are doing the business of power equipment, you still need to shield EMI. EMI can also interfere with power equipment, reducing the quality and efficiency of power delivery.
Especially in the medical, military, and aerospace industries, the selection of GALLOP INNOTEK EMI shielding material makes a huge impact on the stable operation of equipment.
How to Achieve EMI Shielding?
There are many methods to achieve EMI shielding. Different types of EMI shielding methods can be suitable for your different electronic equipment. Here are 5 types of EMI shielding methods commonly used.
Conductive Fabric
Through the electroplating process, the fiber cloth is plated to make it more conducive. Typically, you can select nickel, copper, or carbon as the plating coating. GALLOP INNOTEK conductive fabric can provide excellent conductivity and shielding ability. At the same time, it has chemical resistance and antioxidant capacity.
Because the fabric itself has flexibility, conductive fabric is widely used to produce shielding work clothes. You can also use conductive fabric to produce other EMI shielding products, such as conductive fabric-over-foam and conductive adhesive tape.
Conductive Foam
GALLOP INNOTEK conductive foam is an EMI shielding barrier evolved from conductive fabric. Conductive foam is made by wrapping conductive fabric around the polymer foam material.
The conductive fabric actually serves as a conductive coating that absorbs and reflects electromagnetic waves, thereby achieving EMI shielding. The inner foam is compressible, protecting the electronic components from external damage.
Conductive Rubber
GALLOP INNOTEK conductive rubber is a rubber material filled with metal fillings like silver powder, metal fiber, etc. Conductive rubbers can maintain the elasticity and flexibility of rubber.
Under the premise of ensuring electromagnetic tightness and water vapor sealing capability, the conductive rubber can be designed into different sizes and shapes. Conductive rubber is highly suitable for electronic components that require long-term stability in EMI shielding and high conductivity.
Conductive Silicone
GALLOP INNOTEK conductive silicone is a paste material to make a tight bond between circuit boards. The metal or carbon particles in conductive silicone can stably deliver the current and signal. While the silicone is durable and heat-resistant.
FIP Gel is a type of conductive silicone. It uses pure silver, silver-aluminum, silver-nickel, or nickel-coated graphite powder as high-conductivity particles. GALLOP INNOTEK FIP Gel is suitable for use with a 5G high-frequency signal, providing effective shielding.
Conductive Coating
Conductive coating is also conductive paint. It is a coating that can prevent electromagnetic interference. Typically, copper, silver, and other composite materials are conductive. You can use it to paint or spray insulating non-metallic or non-conductive surfaces.
The biggest advantage of conductive coating is that there is no size limit. It can be used to paint parts of any size and shape.
Yes, there is. EMI can be divided into narrowband EMI and broadband EMI depending on frequency range.
Narrowband EMI happens at discrete frequencies. It is very common in life. The noise of the radio and the screen on the TV is distorted, all caused by narrowband EMI. The interference is not serious and can be ignored.
While broadband EMI occurred at a wide spectrum and occupied a big part of the electromagnetic spectrum, which means it will interfere with electronic equipment a lot.
There are many methods to test the effectiveness of EMI shielding materials. The most common use method is insertion loss test. This method can measure how much electromagnetic energy is lost when through the shielding materials. Then use a network analyser to test the signal strength change differently, thus check the EMI shielding effectiveness.
