Signal Performance Features
- Controlled Impedance Support Support 50Ω, 90Ω, 100Ω differential impedance for USB, LVDS, HDMI, high-speed serial signal; impedance simulation and coupon test available.
- Signal Integrity Stability Continuous copper trace without connector transition, reduce insertion loss, reflection and crosstalk compared with separate FPC + wire harness.
- Low Noise & EMI Control Can design continuous ground plane across rigid-flex transition zone, good shielding for industrial sensor and medical low-noise acquisition circuits.
- High-speed capability Adhesiveless PI flex material has stable Dk, less signal attenuation for high-speed differential signal transmission.
- Important note：Bending deformation will slightly change impedance; we will provide DFM suggestion to avoid high-speed differential lines located inside dynamic bending zone.
