Overview

As evolving telecommunication, industrial automation and medical applications demand higher speeds and smaller form factors, designers need to maximize PCB real estate without sacrificing performance. The NeoPress High-Speed Mezzanine System’s modular design achieves both high- and low-speed signals at 28 Gbps with tunable differential pairs (between 85 or 100 Ohms). Designers need only one connector for different speeds; therefore, they create space savings on the PCB.

SMT connectors are permanently affixed, making it virtually impossible to reuse PCBs. Also, when an SMT termination fails, attempting to rework it creates a short. Even though PCBs are expensive and being able to reuse them would create a cost savings, designers are reluctant to use press-fit mezzanine connectors because they typically offer lower signal integrity than SMT. NeoPress* High-Speed Mezzanine System has been engineered to provide compliant-pin termination while minimizing near-end and far-end crosstalk to match the signal integrity of NeoScale™ SMT Connector. The compliant pin enables designers to rework the board when necessary and maximize its use without having to sacrifice signal integrity.
