What are all the computer board-to-board connectors? What are the problems that need attention?

A computer board to board connector is an electronic component used to connect two circuit boards that can transmit electronic and electrical signals. Board to board connectors play an important role in electronic devices such as computers and servers. Here we introduce some common computer board-to-board connectors and the problems they need to pay attention to.1.2.54mm board-to-board connector2.54mm board-to-board connector is one of the most common board-to-board connectors and is suitable for the connection of most electronic devices. It has a pitch of 2.54mm and a typical pin count of 2 to 40. This connector is characterized by simplicity and reliability, with a simple structure that makes it easy to install. However, it should be noted that due to its more pins, if not used properly can easily cause a short circuit, resulting in circuit failure.2.1.27mm board-to-board connector1.27mm board-to-board connector is a kind of dense board-to-board connector, suitable for connection between circuit boards, with the height, width, pin density and impedance control and other aspects of the advantages. It has a pitch of 1.27mm and a pin count of generally 2 to 100. However, because of its smaller pin pitch, it needs to be more careful in the process of using it.3.0.8mm Board-to-Board Connector0.8mm Board-to-Board Connector is a high-density connector for connection between circuit boards, with higher pin density and impedance control, etc. It has a pitch of 0.8mm, pin density and impedance control. It has a pitch of 0.8mm and a pin count of generally 2 to 80. Due to its high number of pins, attention also needs to be paid to preventing short circuits and circuit failures. Problems needing attention: 1. Number of pins: in the selection of board-to-board connectors need to consider the number of pins need to be connected to the circuit board, as well as whether the number of pins of the connector is sufficient. 2. pin spacing: different board-to-board connectors with different pin spacing, the need to connect according to the spacing of the circuit board to select the appropriate connector. 3. impedance matching: in the high-frequency circuits, you need to pay attention to the impedance matching of the board-to-board connector, so as not to affect the short circuit and circuit failures. Impedance matching: In high-frequency circuits, attention needs to be paid to the impedance matching of board-to-board connectors so as not to affect the signal transmission and reception effects.4. Board thickness: Different board thicknesses require the use of connectors with different heights in order to ensure the reliability of the connectors.5. Terminals and contact materials: The terminals and contact materials of the connectors should be selected from high-quality materials to ensure that the connectors are stable and reliable.
