The board-to-board connector manufacturer tells you how to choose the connector? There are many types of connectors. Common types are: communication interface terminals, wiring terminals, wire-to-board connectors, and board-to-board connectors. Each category can be subdivided into several categories, such as: Board-to-board connectors include pin headers, female headers, etc.; Wire-to-board connectors include FPC connectors, IDC sockets, simple horn sockets, etc.

So when choosing a connector, from which angles should we consider the connector that is suitable for the product?

1. Pins and spacing
The number of pins and the spacing between pins are the basic basis for connector selection. The number of pins selected for the connector depends on the number of signals that need to be connected. For some patch connectors, the number of pins in the patch headers as shown in the figure below should not be too much. Because in the soldering process of the placement machine, due to high temperature, the connector plastic will be heated and deformed, and the middle part will bulge, resulting in false soldering of the pins. Our P800Flash programmer used this pin header and female header to make the board-to-board connection in the early stage of development. As a result, the pins of the prototype header were soldered in large areas. After changing to 2 pin headers with halved pins, there was no false soldering.

Nowadays, electronic equipment is developing towards miniaturization and precision, and the pin pitch of the connector has also changed from 2.54mm to 1.27mm and then to 0.5mm. The smaller the lead pitch, the higher the requirements for the production process. The lead spacing should be determined by the company's production process level, blindly pursuing small spacing.
