Samtec’s new SEARAY™ 0.80 mm pitch ultra-high density array cable assemblies provide 50% board space savings compared to 1.27 mm pitch 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.
SEARAY™ 0.80 mm pitch array cable assembly — the ESCA Series — offers 50Ω single ended signal routing on 34 AWG micro ribbon coax cable, and it supports PCIe® Gen 3 and SAS3 protocols. The cable assembly features a signal to ground ratio of 4:1, optional screw downs and a minimum cable length of 2 inches. Interconnects are available with 20 or 30 contacts per row in 8 and 10 row designs.
Both cable ends are available in socket and terminal options. SEARAY 0.80 mm pitch board level mates (SEAM8/SEAF8 Series) 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 rugged Edge Rate® contact system increases cycle life and minimizes 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.
