Hello everyone, I am the editor. According to market trends, board-to-board connectors have undergone great changes in recent years, and board-to-board connectors have become smaller and smaller. The current common board-to-board connector pitch is 0.40 mm; although the stack height of 1 mm is a small connector, the main board-to-board connector application manufacturers use board-to-board connectors as low as 0.70 mm or even lower. So how to choose the size of the board-to-board connector? The following editor explains how to choose the size of the board-to-board connector!

A few years ago, the old miniature connectors with a width of more than 4 mm were replaced by 3.40 mm wide connectors. The current board-to-board connector concept is usually in the range of 2.40 to 2.60 mm. In the process of selecting a board-to-board connector, the smaller the better, because the smaller it is, the more available space will increase.

Before we choose to use an ultra-small board-to-board connector, we need to know whether the connector has all the other features you need, and carefully test it to make sure it is strong enough. Then, a socket with a top-mounted connector is needed because this setting can be tracked under the socket and conformal coating can be easily applied. Some disadvantages of top-mounted sockets are that the width of the vacuum pick-up area is often narrow on the socket terminal surface and there is no plastic shell material, but it can prevent the trouble caused by uneven crude oil on the top surface of the socket.

In order to ensure that the selected board-to-board connector can be quickly disconnected, a connector locking function of extra length may be required to realize the board-to-board connector of the required size. Pay attention to more connectors to disconnect Operation usually means greater participation, because it may cause problems with large-scale circuits.
