MAGNETIC SHIELDING MATERIAL AND MAGNETIC SHIELDING SHEET FOR NFC ANTENNA

摘要

The present invention provides a magnetic shielding material which has excellent impact resistance, excellent rework when manufacturing a module, low loss (μ″) and a high real number of permeability (μ′) at 13.56 MHz. The magnetic shielding material comprises: soft magnetic flake powder including an alloy of Fe, Co, Si and Cr; and an organic binder. The Co content in the alloy is 0.5 to 3 atom%, the Si content in the alloy is 18 to 23 atom% and the Cr content in the alloy is 1 to 6 atom%.;COPYRIGHT KIPO 2018
