Board-to-board connectors are connectors that directly connect two or more circuit boards together. Typically, both ends of a board-to-board connector are connectors in the form of pins or sockets, through which signal transmission and power supply between different circuit boards are achieved. Board-to-board connectors are widely used in electronics, communications, computers, medical, industrial control and other fields.

In electronic products, board-to-board connectors are usually used for internal connections, such as PCs, laptops, tablets, smartphones, digital cameras and other devices. Board-to-board connectors can connect motherboards, screens, keyboards, cameras, etc. various parts. In addition, in some industrial control and medical equipment, board-to-board connectors are also widely used to connect various modules, such as sensors, controllers, displays, etc.

The working principle of the board-to-board connector is relatively simple. It realizes electrical signal transmission and power supply between different circuit boards through the cooperation of pins and sockets. The pins are usually installed on one circuit board, and the socket is usually installed on another circuit board. When the two circuit boards need to be connected, the pins and sockets will automatically pair up to form a stable circuit connection.

Compared with other connectors, board-to-board connectors have the advantages of small size, easy installation, and reliable contact. Therefore, they are widely used in electronics, communications, computers, medical, industrial control and other fields. With the continuous popularization of electronic products and the continuous expansion of application fields, the application prospects of board-to-board connectors will become increasingly broad.
