Shin-Etsu is offering a range of electro-magnetic shielding products.
Shielding can be considered as 3 area of concern:
Far field shielding; avoiding disturbing radio frequencies to enter a product by creating a Faraday cage around an electronic circuit.
Near field shielding; eliminating disturbing radio frequencies directly at their source, often an IC or switching transistor. Shin-Etsu offers special dielectric material, called Spinpeda®, to be included in multilayer PCB's or CPS-IC's carrier PCB. With such dielectric material low pass filters can be created, blocking RF disturbance directly at it's source.
Absorbtion; eliminating radio frequency in the free space of an electronic device or product by absorption.
