How do we choose board to board connectors?


How to buy high-quality Board To Board connectors has always been a problem that consumers need to consider, so what aspects should be considered? Below, the connector manufacturer of Yachuang Electronics will teach you several ways to buy board-to-board connectors.






Board to board connector refers to the connection between the board end and the board end. For example, some connector pins and busbars belong to board to board connectors. Now the competition in the connector electronic component market is fierce. From the earliest FPC connector to the withdrawal of the specification and model of board to board connector, the demand for connectors in the field is still large, but it is found that everyone is only connected to the earliest FPC connection, We don't know much about what to pay attention to when purchasing board to board connectors and how to connect them. Let's explain how to purchase and connect board to board connectors.






1、 Consider the mechanical properties of board to board connectors


The mechanical properties of connectors can be divided into insertion force, pull-out force and mechanical stupidity. The reliability of mechanical properties is very important for the connector, because once the inferior connector is inserted, it is likely to cause irreversible damage to the circuit.


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


2. Installation dimension of board connector for plug-in header, the length of the welding pin welded to the PCB requires that the exposed part of the PCB board is greater than 0.5mm.


3. For the board to board connector with dense precision, the model with locating pin shall be selected as far as possible when the PCB space allows, so as to facilitate the operation when manual welding is required.


2、 Consider the environmental performance of board to board connectors


The environmental performance of the connector can be divided into heat resistance, moisture resistance, salt spray resistance, vibration, impact, etc. According to the specific application environment, if the application environment is relatively humid, the requirements for moisture resistance and salt spray resistance of the connector are very high, and the metal contacts of the connector should be prevented from rusting.






4. Whether there is anti stupidity design.


5. Whether the materials used contain lead.


6. Contact resistance: small volume board to board connector with low contact pressure. When using with low current and voltage, it is recommended to use gold-plated or silver-plated connector to avoid the influence of film resistance on signal.


7. Observe whether the height of board to board connector meets the welding height of components around PCB. The matching height must be greater than the welding height of components around the PCB, and there must be a certain margin to ensure no interference. Special attention should be paid to the possible height error of components after PCB welding.

3、 Consider the number of pins and pin spacing of board to board connector


The number of pins and pin spacing of the connector are the primary choice for selecting the connector, and the selection of the number of pins of the connector is determined by the number of signals to be connected. Moreover, today's electronic equipment is becoming smaller and more accurate, and the spacing of connectors is also from 2.54 mm to 1.27 mm to 0.5 mm. However, the smaller the spacing, the higher the requirements for the production process.
