Floating board-to-board connectors

FS 0.635 improves tolerance compensation

Middletown, Pa. – The space-saving board-to-board connectors in Phoenix Contact’s FS 0.635 series enable mezzanine PCB arrangements with high-speed data transmission rates up to 30 Gbps. The floating system features a tolerance compensation of up to 0.7 mm in the “x” and “y” directions, as well as 0.6 mm in the “z” direction.

This flexibility within the board-to-board connection minimizes mechanical strain and provides a reliable connection. These properties are particularly important in environments with high vibration, when using several board-to-board connectors side by side, or for automatic insertion using robots.

The combination of floating and high speed is unique on the market: Due to the curved contact, the floating version achieves a data transmission rate of up to 40 Gbps, compared to the rigid version, which supports up to 30 Gbps.

As an additional service, Phoenix Contact offers design-in support with high-speed simulations and S-parameters. The floating female connector strip is combined with a fixed, rigid male connector strip. Because of the floating principle, the FS 0.635 series can achieve stack heights between 8 and 12.6 mm. As a standard rigid board-to-board connection, it can realize stack heights between 6 and 16.6 mm. The entire series is available now in 20, 40, 60, and 80 positions.

Achieve Greater Design Flexibility and Reduce Costs with Chiplets

Sponsored by Keysight

Chiplets are a new way to build a system-on-chips (SoCs) to improve yields and reduce costs. It partitions the chip into discrete elements and connects them with a standardized interface, enabling designers to meet performance, efficiency, power, size, and cost challenges in the 5 / 6G, artificial intelligence (AI), and virtual reality (VR) era. This white paper will discuss the shift to chiplet adoption and Keysight EDA's implementation of the communication standard (UCIe) into the Keysight Advanced Design System (ADS).
