AB6000G

3M EMI Absorber with Shielding AB6000 Series, AB6000S Series, and AB6000G Series Data Sheet October 2008 ™ Description 3M™ EMI Absorber with Shielding AB6000 Series, AB6000S Series and AB6000G Series consists of an insulation layer, shielding layer, absorbing layer and nonconductive pressure-sensitive adhesive. • • • • • Specifications Insulation Layer EMI Shielding Layer EMI Absorption Layer Pressure-sensitive Adhesive (PSA) Layer Supplied on a removable release liner for easy handling and die-cutting Applications The absorber is typically used for applications requiring both electromagnetic shielding performance and absorption function. It is useful for electrical devises for broadband radio frequency range (mobile phone, PDA, PC, BS/CS tuner, LAN, medical and military devices). Common applications include attenuation of conduction and radiation noise suppression and filtering (FPCB and chips on circuit, high speed microprocessor) and resonant peak of enclosed cavities (EMI/ESD/SAR), and electric/ electronic/ RF components (IC/LSL, PCB, FPC, cable, oscillators, RF modules), mechanical bodies (metal can, fame, body, enclosure). Shielding Effectiveness Many factors determine the true attenuation of electromagnetic shielding and absorbing material, including type and thickness of polymer, adhesive type, intimacy of substrate contact, smoothness of application surface, strength and frequency of the EMI signal, etc. However, using standard tests and fixtures, it is possible to determine a value for the attenuation. 3 1 of 4 3M™ EMI Absorber with Shielding AB6000 Series, AB 6000S Series, and AB6000G Series Typical Properties Technical information provided consists of typical product data and should not be used for specification purposes.
