In summary, Panasonic’s narrow pitch connector range has developed the Y4BH series for board-to-FPC applications. With a mounting pitch of 0.4 mm and 0.5 mm, these FPC connectors provide design engineers with mechanical design flexibility due to a height of 1.0 mm and 1.8 mm and double top and bottom contacts. The back-lock structure of the connector simplifies use, makes handling easier, and increases the reliability when the FPC is bent. The Y4BH series features differential impedance matching (100, 90, 85 Ω) and is compliant with various high-speed transmission standards.
