Today\'s electronic components must often meet the requirements of electromagnetic shielding and EMI, and the effective control of the radiation and absorption of various electromagnetic waves requires technological solutions. RFI and EMI shielding and absorbing materials such as 3M CN3490 CIRCLE-0.875"-250 can meet the requirements of electromagnetic shielding and EMI, and become the most frequently used shielding and absorbing materials.

3M CN3490 CIRCLE-0.875"-250 is a silver-plated copper mesh tape with a 0.03x 0.03" metal mesh structure and a 0.875" (22.2 mm) externally exposed radius. The tape has a high electrical and thermal conductivity and a 30-mil (0.76 mm) thickness. The adhesive on the back has excellent adhesion resistance, aging resistance, and conformability. Even at a low temperature, it can still stick on the substrate and form a good seal.

3M CN3490 CIRCLE-0.875"-250 has the characteristics of being a good conductor, and its mesh structure can maintain good shielding effect under the conditions of high frequency and vibration. 3M CN3490 CIRCLE-0.875"-250 can form a Faraday cage structure with metal frames, surface tiles and conductive tapes, so as to achieve perfect shielding and EMI absorption. It can be used to form protective shields for electronic components and circuits, reduce the spread of electromagnetic radiation, and absorb parasitic signals, thereby preventing interference with other components or devices.

3M CN3490 CIRCLE-0.875"-250 is widely used in the fields of electronic equipment, system chassis, displays, mobile phones, car audio, and digital products. It can be used in the manufacture and design of electronic products, as well as in the shielding and assembly of circuit boards And the installation station. It has been verified that the shielding effect meets the requirements of electromagnetic compatibility (EMC). The product has excellent electrical and thermal conductivity, anti-electromagnetic interference (EMI) ability, and high-temperature stability, which can provide world-class effective shielding and EMI radiation solutions for a variety of electronic equipment.

In the process of electronic equipment industry, 3M CN3490 CIRCLE-0.875"-250 is increasingly used in the production of electronic products, becoming an important means of electromagnetic protection, effectively avoiding interference between wires, reducing signal interference, and improving the shielding effect of electronic products. In addition, the product is not only convenient to use, but also has the same environmental protection characteristics as other similar products, which can be operated in a wide range of temperature and humidity, as well as having strong acid and alkali resistance and moisture resistance.

Therefore, this shielding and absorbing material can be applied in the electronic industry in a wide range, providing a reliable and effective solution for the protection of electronic components from interference and Ultra-High Frequency (UHF) signals. With its excellent performance and powerful EMI absorbing capability, 3M CN3490 CIRCLE-0.875 "-250 has become a preferred material for the operations of many well-known technology companies.
