As AI computing power continues to scale, signal rates inside AI servers and high-speed optical modules keep rising. Signal integrity, interconnect density and assembly space have become core bottlenecks for next-generation computing hardware design. Constrained by stack height, pinout arrangement and parasitic parameters, conventional interconnect solutions struggle to satisfy high-frequency performance, compact stacking and assembly tolerance requirements simultaneously. The Board-to-Board Socket enables interconnection between two PCBs. Featuring a low-profile form factor, it establishes stable signal paths within limited vertical stacking height and serves as a critical building block for high-density high-speed interconnect architectures.
Engineered for high-frequency signal transmission, this socket reduces insertion loss and crosstalk, meeting stringent requirements for impedance continuity and contact reliability in high-speed interconnect systems. Deployed in GPU and optical module hardware, the Board-to-Board Socket optimizes board stacking layouts and shortens signal paths. It mitigates signal reflection and eye diagram degradation caused by impedance discontinuities, while accommodating floating assembly tolerances to improve overall assembly yield. This enables systems to deliver higher bandwidth with lower latency.
The performance ceiling of high-frequency interconnects relies not only on contact design, but also material selection, contact mechanics, plating processes and mass-production consistency — factors that determine whether a design can transition from prototypes to volume production. Top-link specializes in high-speed precision interconnects, offering Low Profile Sockets and Board-to-Board Sockets. We have optimized contact structures, plating materials and spring elements specifically for AI high-speed applications, balancing high-frequency electrical performance, long-term cycling stability and consistent mass manufacturability. Our solutions provide hardware engineers in the AI computing space with proven, implementable interconnect options to support 112 Gbps, 224 Gbps and 448 Gbps high-speed link development.
