Skin effect

This is a phenomenon in which electric signals are concentrated on the surface side as the frequency increases. At high frequencies, this causes the effective cross-sectional area of the conductor to decrease and the resistance loss to increase. Also, as this skin effect progresses, resistive losses become more dependent on the surface area than the original cross-sectional area of the conductor. As a result, even FPC/FFC, which has a large resistance loss against wires at low frequencies, is no less inferior at high frequencies reaching 10 GHz, and may even be advantageous. We have prepared low-reflection FPC / FFC Connectors that are particularly compatible with high-performance FPC/FFC, and provide solutions that support transmission speeds exceeding 20 Gbps.
