0.40mm pitch, floating type, parallel connection (ST/ST) board to board connector enables high-speed transmission of digital signals. Movable (floating) structure, 0.4mm movable in the X Y direction, and 0.3mm effective mating length in the Z direction. 8.0Gbps (typical reference value based on in-house definition) high-speed transmission is supported despite low profile and space-saving design. Impedance matching: differential 100Ω, which offsets misalignment when the on-board camera module is embedded on the board, significantly improving reliability.
