Rectangular Connectors - Board Spacers, Stackers (Board to Board)) are the key components of rectangular connectors. Plate gasket is a kind of thin sheet material placed between the contact surfaces of rectangular connectors, which is mainly used to strengthen the tightness and stability between connectors and protect the connector contact surface from damage. A stack connector (board-to-board) is a form of rectangular connector specifically designed to connect two or more circuit boards, usually with a multi-layer structure that allows boards to be stacked vertically and electrically connected through the connector. Board-to-board connectors transmit signals and power from one board to another via pins or terminals inside them, enabling tight integration and efficient communication between boards.

Rectangular Connectors - Board Spacers, Stackers (Board to Board)) are widely used in many fields such as communications, computers, automotive electronics, consumer electronics and industrial automation. In the communications industry, they are used for interboard connections for high-speed backplane connectors, switches, routers and other devices. In the computer field, it is commonly used in the internal board connection of servers, workstations, laptops and other devices to improve the overall system performance. In automotive electronics, it is used to establish a reliable electrical connection between the ECU, sensors and actuators to ensure the smooth operation of the vehicle control system.

• 1. What are the types of board-to-board connectors?

  1. Pin headers/pin headers: This is the cheapest and most common connection method, suitable for low-end, large-sized smart devices, development boards, debugging boards, etc. Its advantages are cheap, convenient, stable hard connection, strong overcurrent capacity, and convenient welding and testing. The disadvantages are large size, difficult to bend, large spacing, and it is difficult to connect hundreds of pins.
  2. High-end board-to-board plug-in: This connector is denser than pin headers and is widely used in compact products. Its advantages are a large number of pins, small size, and the ability to achieve more functions within a limited size. The disadvantages are high prices, cannot be plugged and unplugged frequently, and the structural design needs to be fixed.
  3. Thickened board-to-board connector: This connector is suitable for development boards, test boards, and large and fixed devices, such as computer case wiring. Its advantages are cheap and common, and it is very easy to connect and measure when used with pin headers. The disadvantages are large size, difficult to fix, and not suitable for mass production scenarios.
  4. FPC connector: This connector is suitable for smart hardware devices that need to take signals out of the motherboard. Its advantages are flexibility, small size, and changeable shape. It is suitable for connecting the main board with the daughter board, connecting the main board with the peripherals, and wiring that needs to be bent.

• 2. Principle of board-to-board connector?

  The working principle of the board-to-board connector is to achieve the connection between the circuit boards by inserting and matching the pins with the sockets.
  The board-to-board connector mainly consists of two parts: a connection socket and a connection plug. The socket is usually fixed on one circuit board, and the plug is fixed on the other circuit board. When the two circuit boards are installed together, the plug is inserted into the socket, and the metal sheets of the pins and the socket contact each other to achieve electrical connection between the circuit boards. This connection method allows electronic signals and power to be transmitted between the two circuit boards, and is an important part of the internal circuits of electronic products to connect to each other and transmit electronic signals and power.

• 3. Specifications of board-to-board connectors?

  Specifications of board-to-board connectors include spacing, rated voltage, withstand voltage, temperature range, number of PINs, color, etc. Board-to-board connectors are widely used in power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, military manufacturing and other industries due to their strong transmission capacity.
  1. Spacing: There are many spacings for board-to-board connectors, the most common ones are 0.4mm, 0.5mm, 0.635mm, 0.8mm, 1.00m, 1.27mm, etc.
  2. Rated voltage and withstand voltage: The rated voltage is ACDC 60V and the withstand voltage is 250V/min.
  3. Temperature range: The temperature range is -55°C to +85°C.
  4. Number of PINs: There are many options for the number of PINs, such as 10P, 12P, 14P, 16P, 18P, 20P, 22P, 24P, 26P, 28P, 30P, 32P, 34P, 36P, 38P, 40P, 42P, 44P, 50P, 60P, 80P, etc.
  5. Color: The color of the board-to-board connector can be beige, coffee, white, black, etc.
