What Factors Influence The Increase In Demand For Board To Board Connectors?
The growth of board-to-board connector systems stems from their compact design as electrical and mechanical devices utilising Printed Circuit Boards (PCB). A board-to-board connector system enables signal, power, or data transfer between two PCBs.
The board-to-board connector market comprises electrical connectors that interconnect two printed circuit boards (PCBs) for signal, data, and power transmission. These connectors enable compact system design, high-speed data communication, and modular PCB architecture across consumer electronics, automotive electronics, industrial automation, telecom, medical devices, aerospace, and computing hardware.
High-speed data transmission, large numbers of PCB layouts per square inch, and growing demand for robotically controlled and IoT-connected devices drive the need for board-to-board connectors. There are many more manufacturers of automated factories today, so more automotive manufacturers are now utilising advanced driver-assistance and hybrid infotainment systems, leading to greater demand for components that can withstand higher temperatures and vibration. New technological upgrades identify board-to-board connector systems as a critical component in the architecture of future electronic devices.
Innovation With AI Impacts the Future of the Board-to-Board Connector Market
The introduction of artificial intelligence to the design, optimization, and integration of the board-to-board connector market into the development of advanced electronic devices is changing the way these materials are designed. A significant milestone occurred in November 2025, when HARTING launched its AI-enabled connector configurator, which can transform an engineers plain-language input into an instantaneous three-dimensional prototype of the product. The result is a reduced design cycle from weeks to less than one minute, with the added ability to customize and create more accurately chosen connectors.
At the OCP Global Summit 2025 (October 13-16, 2025), Amphenol also demonstrated how high-speed/high-density board-to-board connectors can be engineered specifically for AI Servers and Cloud Data Centers. These products will be able to accommodate higher bandwidths and lower latency, as well as have improved power-handling abilities, all of which are key requirements of the training and inference workloads associated with AI.
These examples of innovation in the field of connectors clearly demonstrate that AI is leading to the development of connector technologies that will enable more intelligent, faster, and more efficient means of connecting electronic devices.
