EMI Shielding Coatings

Usage Personal computer and mobile communication housings and GPS devices

EMI is any electrical signal that disturbs the function of a circuit, cable or other electronic component. EMI can originate from other equipment or from the affected component itself. The number of electromagnetic signals has increased with the ever growing use of computers, mobile phones and other electronic equipment. Due to this reason EMI shielding is acquiring great importance.
