Conductive foam can get a good shielding effect in the frequency range of 100KHz to 1GHz. Regarding the difference between it and all-round conductive foam, let's listen to the editor's explanation.
Conductive foam is made of conductive and anti-corrosion conductive fiber cloth, lined with PU foam with low compression force, and has good shielding effect. Conductive fiber cloth is woven from metal fibers composed of Polyester fibers covered with copper and nickel metal surfaces. The bottom layer of the fibers is copper with high conductivity, and the surface layer is nickel metal that resists oxidation and corrosion. The combination of copper and nickel provides good electrical conductivity and shielding.
Conductive foam is especially suitable for occasions with limited capacity and closing pressure, and the cost is low. It is especially suitable for use in occasions requiring good fit and high-performance shielding. It can be widely used in electronic chassis, casings, indoor chassis, industrial devices, laptops, mobile communication devices, etc.
However, all-round conductive foam is a brand-new shielding material, which is made of PU foam through electroplating. It is an X, Y, and Z three-axis conductive conductive material. The shielding effect is higher than that of traditional conductive foam. It can meet the ever-increasing shielding performance requirements of computers and communication equipment. All-round conductive foam is very suitable for the shielding of the input and output (I/O) interfaces of the equipment, and is also suitable for the shielding at the interface.
Advantages of all-round conductive foam:
1. Very good conductivity, high shielding effectiveness (≥80dB)
2. Good oxidation resistance, anti-corrosion performance
3. Very good wear resistance, high reliability (≥1 million times)
4. Very soft, suitable for occasions that cannot provide greater pressure
5. Low price, it is an ideal shielding material
6. The installation method is simple and diverse, suitable for pasting and slotting
7. The product complies with ROHS, Halogen Free, REACH, requirements.
