High-speed elevated arrays

2 September 2015 Interconnection

Samtec’s newly released SkyRay elevated array system offers design flexibility and high-speed performance without sacrificing signal integrity. The system supports 28+ Gbps applications, as well as PCIe and XAUI specifications.

SkyRay is a three-piece system consisting of one riser and two receptacles (TPAR/TPAF series) that when mated provides an elevated 35 mm stack height. High-density wafers inside the riser feature a helical crossover design to greatly reduce crosstalk in 100 Ω, differential applications. A choice of 1, 2 or 3 module configurations is available with 50 differential pairs per module on a staggered 1,50 mm x 1,75 mm pitch.

The elevated stack height aids in system airflow and accommodates for wide misalignment tolerances in the X-Y axes. Low-profile receptacles with solder ball termination allow low thermal mass for easy reflow processing and a removable riser simplifies stack height changes for increased system flexibility.

Also available are stack heights from 18 mm to 40 mm for increased flexibility, an installation cap for manually mating the system, along with an extraction tool for removing the reusable riser should receptacle replacement be necessary.
