EMI Suppression at FPC Edges
EMI Shielding Film for High-Speed FPCs (Wrapping Type)

Overview

Replacing coaxial cables with flexible printed circuits (FPCs) helps reduce the thickness of smartphones and other advanced electronic devices. However, unlike coaxial cables, conventional FPCs are not completely enclosed by shielding, which can allow electromagnetic noise to radiate from their exposed edges. TATSUTA’s WILMINA® SF-PC®4300-Z2-C is a wrapping-type EMI shielding film that can be applied to both sides of an FPC and wrapped around its edges. This structure effectively suppresses radiated noise from FPC edges while maintaining the flexibility of the FPC.
