Top 5 mezzanine connectors

A mezzanine connector is an electrical connector that connects one printed circuit board (PCB) to another PCB.. The term is commonly used when one PCB is arranged in a parallel manner, with one board placed above the other.

These are highly useful to solve packaging issues. There are several types of mezzanine connectors used for a wide range of applications. This article discusses some of the most common types of Mezzanine connectors available in the market.

ExaMEZZ®

ExaMEZZ® connectors are one of the prominent mezzanine connectors targeting high-speed signalling. The system enables 25Gb/s electrical performance and anticipates further increase in the bandwidth to 56Gb/s in the future. These connectors offer improved integrity with beam on beam contact interface. It has an exceptionally low mating force and excellent contact normal force. The ExaMEZZ® connector plastic body been optimized for mezzanine applications, with hermaphroditic mating. One part number can often be used on both boards.

TwinMezz®

With highest data rates, signal density and lowest insertion force, TwinMezz® connectors provide superior electrical performance.. It is capable of meeting the design requirements for 20Gb/s mezzanine applications. The open pin field designs add to flexibility of the connectors offering mixed differential, single-ended and power pin assignment in a single connector. TwinMezz® connectors also feature Amphenol ICC's patented BGA connector termination for easy surface-mount attachment and efficient trace routing.

MezzoStak®

MezzoStak® connectors are 0.50mm fine pitch connectors, which can serve a wide range of applications with comprehensive position sizes and stack heights. They are efficient in demanding environments and highly reliable. The connectors also feature a hermaphroditic design which supports easy mating. Two versions offer a choice between supplemental PCB hold-downs and pegs for short overall length.

MEG-Array®

MEG-Array® connectors are high-density, high-speed coupled with discrete contacts. This offers mechanical design flexibility with wide range of position sizes and PCB stack heights. 1.27mm x 1.27mm array of discrete circuit contacts allows flexible ground distribution to optimize high speed signal integrity at speeds up to 28Gb/s. Amphenol ICC's advanced manufacturing supports a patented BGA interconnect design

BergStak®

BergStak® family is the ideal board-to-board connector solution for high-speed and high-density applications. These industry-proven connectors are known for its reliability and robustness. To meet future application demands and challenges for higher speed and smaller form factor, the BergStak® family has evolved from the original 0.80mm pitch to finer pitch 0.50mm and also higher speed performance in BergStak+™ and BergStak HS™ product series. These are also compatible with next-gen PCIe and SAS 3.0 with its higher speed and reliability.

Consider connector density, speed performance and mating requirements to choose the bestmezzanine connectors , matching your application designs.
