1.03-4-AB5050

Nowadays, with the development of technology, the phenomenon of electromagnetic interference and radio frequency interference, commonly known as EMI and RFI, are becoming increasingly serious. The electromagnetic environment has gradually been recognized by the public and the whole industry, and the requirements for EMI and RFI have gradually increased. In order to meet the requirements, many new materials have been used in electronic systems and peripheral products, including EMI and RFI-shielding and absorbing materials.

The 1.03-4-AB5050 material series produced by Shanghai Feiyu Electronic Material Co., Ltd. belongs to EMI and RFI shielding and absorbing materials. The whole series of materials are composed of polyester/foam/foil/polyester and foam/foil/polyester four main materials, which can reduce the number of process layers and reduce the cost. The products also have the characteristics of lightweight, soft, warm and comfortable.

The 1.03-4-AB5050 material series is widely used in computer communication field, laptop, mobile phone, PDA, radar, wireless communication equipment, GPS and other high frequency communication and electronic equipment. The material has a good function of absorbing and shielding electromagnetic radiation in the frequency range of < 30MHz China Digital Broadcasting SFN/DTT CATV UHF Satellite Electronic Detection and Monitoring band. It can effectively reduce the radiation interference of electronic products on the surrounding environment, protect the communication system from being affected, and optimize the communication environment.

Working Principle

The 1.03-4-AB5050 material series is a three-dimensional / double composite special EMI shielding and absorption material. The basic structure starts from the inner layer, which is a three-dimensional metal element made of three-dimensional knitted wire mesh, and is then covered by a high-density foam layer, which is then bonded with a special composite film and an aluminum foil layer. The combination of such a multi-layer structure ensures that the 1.03-4-AB5050 product series has good ability of EMI shielding and absorption. It can form a Faraday cage around the EMI/RFI sensitive component, so that the interference current is guided along the three-dimensional metal element and scattered in all directions in the structure of the Faraday cage, while the interference energy is absorbed by the foam and aluminum layer, so that the purpose of shielding and absorption is achieved.

At present, the 1.03-4-AB5050 product series has become the preferred EMI / RFI shielding product for many communication equipment and electronic product manufacturers, mainly due to its low loss, flexibility, easy installation and wide frequency bandwidth. In the face of increasingly severe EMI and RFI interference, the 1.03-4-AB5050 material series is definitely a good defense choice.
