High-density array cable assemblies

4 November 2015 Interconnection

Samtec’s SEARAY 0,80 mm pitch, ultra high-density array cable assemblies provide 50% board space savings compared to 1,27 mm pitch SEARAY systems.

With performance to 15 Gbps and up to 300 total Edge Rate contacts, this cable system is designed for rugged, high-speed applications where space is limited.

The 0,80 mm pitch ESCA series offers 50 Ω single-ended signal routing on #34 AWG micro ribbon coax cable with 20 or 30 contacts per row in 8 and 10 row designs. The cable assembly features a signal to ground ratio of 4:1, optional screw downs and a minimum cable length of 5 cm.

Both cable ends are available in socket and terminal options. Board level mates (SEAM8/SEAF8) are available in 2 mm and 5 mm body heights for design flexibility and standard lead-free solder charge terminations to simplify IR reflow termination and improve solder joint reliability.

The featured Edge Rate contact system increases cycle life and minimises the effects of broadside coupling, which decreases crosstalk for superior signal integrity performance and impedance control. This rugged contact system is also less prone to damage when ‘zippered’ during unmating.
