The 0.4mm Board to Board Connector, meticulously developed by yztech, is an ideal choice for precise inter-board connections in high-density electronic devices. As an innovative product in the small-pitch connection field, its 0.4mm ultra-fine pitch design saves more PCB space than 0.5mm board to board connector, especially suitable for devices with strict size requirements such as smart watches and micro-sensors. The connector housing is made of high-temperature resistant LCP material, certified by UL94 V0 for flame resistance, and can work stably in extreme environments from -55℃ to 125℃, ensuring long-term reliability of connector board to board connections.​
