Board-to-Board Connectors

PRECI-DIP’s board-to-board connectors use precision-machined contacts to ensure stable electrical performance and high contact reliability in PCB interconnections. Their custom design supports direct board stacking with consistent contact alignment and durability over repeated mating cycles. Available in multiple series with various contact layouts and termination types, they offer flexibility for design, assembly, and maintenance. These connectors are suited for demanding environments where durability and connection quality are critical.

Nicomatic’s Matr’YX series BGA board-to-board connectors meet the need for absolute ruggedness and compactness that defense, aeronautics, and space applications demand. Matr’YX offers an exceptional density of over 70 contacts per cm² (available from 49 to 301 contacts). Thanks to modular stack heights ranging from 5.5 mm to 14.5 mm, this series delivers critical space and weight savings. This connector stands out with a unique feature for a 1 mm pitch: 4-point contacts combined with an optimized gold layer, which drastically reduces fretting corrosion and ensures long-term reliability. Designed for maximum mechanical robustness, the Matr’YX withstands extreme vibrations (30 gRMS from 5 to 2000 Hz) and thermal cycling from -55 °C to +125 °C. It is also compliant with ECSS outgassing standards for space thermal vacuum environments, while ensuring high-speed data transmission reaching 12.5 Gb/s NRZ and 25 Gb/s PAM4.

Phoenix Contact’s FP 0,8 series board-to-board connectors features innovative ScaleX technology. The unique double contact ensures a reliable, robust connection and high tolerance compensation when plugging. Due to their excellent signal integrity, they are ideal for high-speed data transmission up to 52 Gb/s. The FP 0,8 series board-to-board connectors are available in three versions. The shielded versions are optimized for a very high level of electromagnetic compatibility (EMC). Two unshielded versions are divided into unshielded and shieldless. These are characterized by AOI-capable contacts and by a PCB footprint that is compatible with the shielded version.

Amphenol LTW (ALTW) SSL 1.1 simplifies mechanical design with a rugged, panel-mounted I/O interface featuring a low-profile housing that integrates seamlessly with PCB layouts. The result is faster integration, improved design flexibility, and a robust connection solution for demanding environments. Optimize your design with board-to-board connectors that maximize available space and deliver high pin density in compact applications. Designed for electronics, industrial control panels, and data systems, they provide a reliable connection between internal PCBs while reducing design complexity.

The Samtec FTSH series is a 1.27 mm centerline terminal strip (“header”) available in surface-mount and through-hole designs, and in vertical and right-angle configurations. These high-reliability connectors are available in 2 to 50 pins per row, with selective gold/tin plating in flash or light gold. Options to improve manufacturability include shrouds, locking clips, guideposts, pick-and-place pads, ejector and keying shrouds for mating with cable assemblies, and tape-and-reel packaging. Samtec FTSH terminal strips are commonly used as JTAG connectors. Common sizes are 10-pin (2 x 5), 14-pin (2 x 7), and 20-pin (2 x 10). JTAG connectors can be either through-hole or SMT, and either shrouded or unshrouded. The FFSD series is a popular low-profile ribbon cable assembly that mates with the FTSH series.

METZ CONNECT board-to-board connectors deliver the compact design, flexibility, and reliability that PCB applications demand. Available with horizontal and vertical wire entry options, these connectors integrate seamlessly into any design. With THR and SMT-capable variants, they are built to perform in today’s most demanding, high-speed automated production environments.

NOVASTACK 35-HDP 12 from I-PEX can transmit up to 40 Gb/s per lane in a very compact form factor, with a nominal mated height of just 1.2 mm and a 0.35 mm pitch board-to-board connector. This connector is equipped with four power contacts, each capable of delivering up to 4.5 A per pin. In addition, ZenShield technology provides 360° shielding around both the plug and receptacle, significantly reducing electromagnetic radiation. NOVASTACK 35-HDP 12 offers a versatile pin count and transmits up to 40 Gb/s/lane.

In addition to PCB micro-D and nano-D connectors, Axon’ Cable offers an alternative solution for PCB connection: plastic interposers made with twist-pin contacts. With a thickness of 0.65 mm, they are designed for solderless connection in a space-constrained area. Axon’ interposers are available with 9, 15, 22, 26, or 31 ways. They can be simply compressed between two rigid PCB sections. This is an ideal solution to connect 2 PCBs in highly space-constrained equipment.

ATTEND’s floating board-to-board connectors are designed to address alignment challenges in high-density electronic systems. Featuring an integrated floating mechanism with ±0.5 mm X- and Y-axis tolerance, the connectors help compensate for assembly misalignment, reduce mechanical stress, and maintain stable electrical connections. Supporting high-speed transmission up to 8 GT/s (PCIe 3.0), they offer a compact 0.5 mm pitch design with 60-, 80-, and 100-position configurations for space-constrained applications. The floating architecture, combined with compliant contact technology, helps absorb vibration, shock, and thermal expansion while ensuring reliable signal transmission across a wide operating temperature range from -40 °C to +105 °C. This makes the connectors particularly suitable for industrial automation, robotics, automotive electronics, AI and edge computing platforms, transportation systems, measurement equipment, and medical devices.
