0.4mm Board to Board Connector

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.​

 

The internal terminals are made of gold-plated phosphor bronze, with a contact resistance as low as 8mΩ and a mating life of more than 1000 times, which can maintain stable transmission even in frequently plugged scenarios. The unique foolproof structure design effectively avoids pin damage caused by misplugging, and is compatible with the surface mount technology of board to board pcb connectors, adapting to the efficient assembly needs of automated production lines. Although mainly used in consumer electronics, its structural strength and vibration resistance have reached the standard of automotive board to board connector, and can be used for internal connections of small automotive electronic modules. Whether building a signal transmission network for multi-layer circuit boards or realizing the docking between the main board and sub-board of micro devices, this 0.4mm board-to-board connector has become a core component of high-density connection solutions with its excellent precision, stability and compatibility.
