High-Flexibility Shielded FPCs
EMI Shielding Film for High-Speed FPCs
(High Bending Durability)
WILMINA®
SF-FT®8905 -C
Overview
As foldable smartphones and wearable devices become more widespread, flexible printed circuits (FPCs) must withstand repeated bending while maintaining reliable electrical performance. EMI shielding films used in these applications must also offer excellent bending durability and effective shielding performance for high-speed signal transmission. TATSUTA’s WILMINA® SF-FT®8905 -C is a high-flexibility EMI shielding film designed to meet these requirements. It combines excellent bending durability with high-frequency electrical performance, making it suitable for FPCs in devices subject to repeated bending.
