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.
