How to choose board to board connector? The manufacturer of pin connector tells you

Board to board connectors are board to board connections. For example, some connectors are board to board connectors. Now the market of connector electronic components is very competitive. From the earliest appearance of FPC connector to the withdrawal of board to board connector, it seems that the demand for connectors in this field is still quite large. However, it is found that people only connect the earliest FPC connection, and it is not clear what to pay attention to and how to connect when purchasing board to board connectors. Here's how to explain board to board connectors.

Pay attention to the selection of board to board connectors.

1. The voltage loaded on the observation board to board connector shall not exceed 50% of its rated voltage.

2. Installation dimension of board connector for plug-in connector, the length of pin welded to pin connector PCB shall be greater than 0.5mm

3. For the board to board connector with dense precision, the pin pin female seat with locating pin should be selected as far as possible when the PCB space allows, so as to facilitate manual welding.

4. Whether there is anti daze design.

5. Whether the materials used contain lead.

6. Contact resistance: low contact pressure of small board to board connector. For low current and low voltage use, it is recommended to use gold-plated or silver plated connector for pin bushing to avoid the influence of film resistance.

7. Observe whether the height of the board to board connector after docking conforms to the welding height of the components around the PCB. The matching height must be higher than the welding height of components around PCB, and a certain margin must be ensured to avoid interference. Special attention should be paid to the possible height error of components after PCB welding.
