Press-fit mezzanine system

Molex introduced the NeoPress high-speed mezzanine system, a complete and flexible press-fit/compliant-pin solution that allows board rework whenever required.
The modular system, with tuneable differential pairs, low stack heights and compliant-pin terminations with a staggered interface configuration, offers data rates up to 28 Gbps, making it ideal for new, space-constrained telecom, automation and medical applications that demand higher speeds and smaller form factors. A mirrored interface allows compact stack height and simplified PCB routing.
“PCBs sometimes need to be reused or reworked,” explains Nadine Dytko-Madsen, new product development manager at Molex. “Traditional SMT connectors are permanently affixed, making it virtually impossible to reuse PCBs, and when an SMT termination fails, attempting to rework it creates a short. An alternative – press-fit mezzanine connectors – would allow reuse, but they typically offer lower signal integrity.”
The NeoPress system solves these issues by providing compliant-pin termination while minimising near-end and far-end crosstalk, matching the signal integrity of NeoScale SMT connectors. Moreover, the compliant pin allows designers to rework the board and maximise system utility without sacrificing signal integrity.
A patent-pending modular triad wafer design includes high-speed differential pairs that can be tuned to 85 to 100 impedances, creating a flexible, customisable system. System options include four triad configurations, high-speed single-ended traces and low-speed single-ended lines and power contacts. These options allow PCB designers to conserve PCB real estate by supporting low- and high-speed signals and power requirements with one compact connector.
