Product Overview
These shielding films provide excellent conformability to steps on rigid-flex FPCs (rigid-flexible printed circuit boards). SF-PC6000-U1N2/U1-US provide high conformability when the shielding film is applied across the boundary between the rigid board and FPC sections. SF-PC6000-U1N2 is widely used for rigid-flex FPC applications, while SF-PC6000-U1-US is used in applications such as camera modules where ultrasonic cleaning is performed, thanks to its resistance to chemicals used in ultrasonic cleaning.
Features
-
Conformability to steps up to 400 µm
The product structure provides excellent conformability to surface steps up to 400 µm. -
Isotropic conductive adhesive
An isotropic conductive adhesive is used without a separate shielding layer. The adhesive layer itself provides the shielding function, achieving shielding effectiveness of 55 dB or higher at 1 GHz, comparable to SF-PC5600/5900. -
Resistance to ultrasonic cleaning
SF-PC6000-U1-US is resistant to cleaning solutions used in ultrasonic cleaning processes for applications such as camera modules.
* Resistance is not guaranteed for all ultrasonic cleaning solutions.
