Product Description:
Our 4-Layer FPC for Dual-Screen Display is designed to provide a reliable and efficient solution for devices requiring seamless connectivity between two LCD screens. The FPC features two independent gold finger connectors that ensure stable connections to dual displays. The material design includes precision IC solder pads for advanced functionality and enhanced signal integrity. To provide additional structural support, an FR4 stiffener is applied to the connector areas. EMI shielding film is integrated on both sides of the FPC to minimize signal interference, ensuring optimal performance during operation.
Key Features:
•Dual Gold Finger Design: Dedicated connections for two LCD screens.
•Precision IC Solder Pads: Supports high-density and complex electronic components.
•FR4 Stiffener: Provides mechanical stability to connectors.
•EMI Shielding: Dual-sided shielding to prevent signal interference during operation.
•4-Layer Circuit Design: Offers high reliability for advanced electronic applications.
Sample Specifications:
•Material: Polyimide base with FR4 stiffener at connector positions.
•Gold Fingers: Two sets, customizable per project requirements.
•Shielding: Dual-sided EMI shielding film.
•IC Pad Tolerance: ±0.05mm for high-precision applications.
•Thickness: 0.3mm ± 0.03mm (excluding stiffener).
