This improvement was made possible by their unique laminated design: The IFM10M sheet consists of a magnetic layer and a copper-plated layer of polypyrrole resin and no longer requires a layer of double-sided tape. With these sheets they have succeeded in creating an ultra-thin copper cladding of just 1 µm based on plating process technology developed by Achilles Corporation. The low profile of the new noise suppression sheets are suitable for use in slim devices such as smartphones, tablets, notebooks and stylus pens.
As electronic devices, including smartphones, have become smaller and thinner as well as more multifunctional with a higher degree of integration, the need for better and more efficient noise suppression is growing, for example, to ensure the reliable function of NFC (near-field communication) and wireless charging in the same device. In addition to noise suppression within the circuit using EMC components and standard circuit design measures, and it is essential to suppress unexpected and unwanted interference. Magnetic sheets are used to absorb noise and prevent from leaking externally or reflecting internally.
