Double-sided FPC
Features
□ Enables high-speed transmission with low loss at the rate of at
least 1 Gpbs.
□ Possible to make a highly noise-resistant FPC with double layers
provided.
□ Incorporating a microstrip structure, thus ensuring exact
impedance matching.
□ Possible to provide applications integrated with high-speed
transmission connectors.
