Development of smartphones and other mobile devices is still focused on the miniaturisation of the individual components, while the range of functions increases. Apart from a PCB layout that supports EMC, adequate additional shielding of the devices is playing an increasingly important role. Noise suppression sheets such as the ultra-thin IFL16 are a space-saving answer to this requirement. They can prevent emitted interference from penetrating the device or can prevent reflections created within the device from affecting the function of other devices.
A growing number of devices use a stylus pen for input, which works on the principle of magnetic induction. In order to improve sensitivity, these devices use magnetic films for the inductive sensor unit of the display. This simultaneously demands both a high level of magnetic permeability and a very thin film. On the basis of its substantial competence regarding materials and technology, TDK is offering attractive solutions for such applications with its IFL16 foil.
