Shielding film for high-speed signal transmission FPC (wrapping)
UL94 VTM-0 (combined with Kapton50H)

In order to prevent radiation noise from the edge faces of FPC, this shielding film for high-speed signal transmission FPC can be bonded to both sides of FPC to wrap it. For shielding edges, there is a way of connecting GND by TH (through-hole), but in such a case, boards become rigid, losing the original flexibility of FPC. By using the SF-PC4300-Z2-C, the flexibility of FPC is secured, and noise suppression measures can be taken for FPC edges.
Wrapped shield of FPC edgesBy improving the product strength through the adoption of polyimide in the protection layer, wrapping is possible and noise suppression measures can be taken for FPC edges.
Compatible with 200μm stepsBy thickening the adhesion layer and using an isotropic conductive adhesive in order to enable wrapping, the joint resistance value is stabilized together with followability to 200μm steps.
