SAN JOSE -- Sanmina today announced significant advances in high performance backplane technology.

Sanmina also announced the capability to perform high-speed production vector network analysis (VNA) testing for backplanes.

Sanmina said it is now shipping backplanes capable of operating at frequencies up to 40GHz. This increase in performance represents a significant advancement when compared to backplane available as recently as a year ago. Newer materials that provide improvements in copper foil treatments, advances in resin systems and reduced anisotropy in glass reinforcements have allowed designers to bundle these technologies resulting in higher transmission frequencies. These technologies enhance the performance of the backplane along with improvements to via structures and their proximity to other copper features, resulting in further enhancements to signal management.

Sanmina has also implemented VNA and high speed, robotic time domain reflectometry (TDR) testing in production.  This has been made possible by advancements in both robotics and high speed data acquisition and processing.

"Over the past 12 months we've been working on a number of new technologies to achieve this breakthrough in high-speed backplane performance," said Alex Scroppo, senior vice president, Backplane and Cable Division at Sanmina. "Advances in PCB and backplane bandwidth are crucial to achieving the ever increasing data rates needed by telecommunications hardware and service providers."
