  Precautions for board-to-board connectors and operating points that are easy to overlook

  1. When using the board-to-board connector, be careful not to plug it in reverse or misplacement. When it is not smooth, remember not to forcibly pull and plug, so as to avoid damage to the internal pins of the connector.

  2. The spacing between the positive and negative leads of the board-to-board connector should be consistent with the position of the PCB board solder holes. If a plug is used to force a circuit board with a mismatched hole spacing, the lead wires will be stressed, causing short-circuit or leakage of the board-to-board connector. The phenomenon of rising current.

  3. Since the board-to-board connector has many pins, and the pin wiring inside the interface will be worn every time it is inserted, it is necessary to avoid excessively frequent plugging and unplugging of the connector, otherwise it will affect the board-to-board The service life of the connector. In addition, it is necessary to pay attention to whether the pins are deformed when inserting the board-to-board connector to avoid violent insertion and cause the pins to break or bend.

  4. When tightening the screws at both ends of the board-to-board connector, be careful not to make the screws on both sides firm, otherwise the screws on either side will be loose, which will easily cause the connector to skew and cause damage.

  Easily overlooked operation points:

  1. Normally, after using the equipment for a certain period of time, please stop it for a few minutes, and wait for the operating elements of the board-to-board connector to have enough time to dissipate heat, otherwise the metal terminals in the connector will easily cause acceleration components when the load is working for a long time Aging and other conditions are also due to the small size of the connector. If it cannot withstand the excessively high operating temperature, it will also cause damage to the connector components.

  2. Regarding the working environment of the board-to-board connector, it is generally because the internal terminals of the connector are mostly electroplated parts, so please be careful not to apply the connector to some excessively humid environments, otherwise the humidity will affect the insulation performance of the connector . Therefore, when selecting connectors, we must pay attention to considering the humidity in the working environment, whether it will affect the performance of the board-to-board connector.

  3. Since the plastic box of the board-to-board connector breaks during the injection molding stage, the usual process is to inject molten plastic into the metal tire film, and then quickly cool it to form. Therefore, after the connector is used for a period of time, some grease and other liquids will accumulate in the connector. It is also possible that the oil of some components in the circuit has dripped. Therefore, the connector needs to be cleaned from time to time. Otherwise, too much accumulation in the rear will cause the oil of some components in the circuit to leak into the circuit.

  4. The board-to-board connector interface has more internal terminal pins, so in the daily use of the connector, please pay attention to keeping these jacks clean, otherwise the board-to-board connector will accumulate and attract after long-term operation. To a certain amount of dust and debris, so if it is not handled in time, it will not only affect the performance and use of the connector, but also may cause some safety hazards.
