How to choose the size of board-to-board connectors

According to market trends, board-to-board connectors have changed considerably in recent years, with board-to-board connectors becoming smaller and smaller. Currently the most common board-to-board connector pitch is 0.40 millimeters; although a stack height of 1 millimeter belongs to the small connectors, the major manufacturers of board-to-board connector applications use board-to-board connectors as low as 0.70 millimeters or even lower. So, let's say, about how to choose the size of board-to-board connectors? A few years ago, old miniature connectors with widths over 4 mm were replaced by 3.40 mm wide connectors, and current board-to-board connector concepts are typically in the 2.40 to 2.60 mm range. In choosing a board-to-board connector the smaller the better, as the smaller it is the more space available will increase. Before we choose to use an ultra-small board-to-board connector, we need to know if the connector has all the other features you need and test it carefully to make sure it is robust enough. Then, a receptacle with a top-mounted connector needs to be used because this setup allows tracking under the receptacle and conformal coating can be easily applied. Some of the disadvantages of top-mounted receptacles are that the vacuum pickup area width tends to be narrower on the terminal face of the receptacle, and there is no plastic shell material, but it prevents the trouble associated with uneven rise of crude oil on the top face of the receptacle. In order to ensure that the selected board-to-board connector can be disconnected quickly, additional length dimensions of the connector locking function may be required to achieve the required size of the board-to-board connector, be aware that more connector disconnect operation, usually means greater involvement, because it may lead to problems with large-size circuits.-2、About Evergrande Electronic Products Network platform related to the introduction and sales of products briefly: Evergrande Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable products we can provide solutions, please contact the following Division I business personnel; If you have related [connectors | wire harness | wire and cable products] sales / resources and promotion needs, please click on the "¡¡ Business Cooperation ←" with the person to discuss!
