In electronic equipment, board-to-board connectors have an important role in transmission performance, and connector failure will lead to the overall performance of the equipment or can not work properly, so the stability of the test and analysis is very important. In this paper, Dickey precision connector manufacturers will explore and analyze the board-to-board connector failure causes, test methods and maintenance strategies.

First, the reasons for the failure of the board-to-board connector:

1. Connection of physical damage: physical damage may lead to the connector shrapnel, pin, row of pins and other failures, affecting the transfer of current leading to electrical components can not work properly.

2. Connector aging: prolonged use, the connector may occur aging phenomenon, making poor contact, resulting in signal interference, contact instability and other issues.

3. Poor connector contact: poor connector contact may be due to oxidation or corrosion on the metal contact surface, resulting in signal interference, contact instability and other issues.

Second, the board-to-board connector failure test methods:

1. Appearance inspection: through appearance inspection, you can understand whether the connector is physically damaged, whether the contact surface is oxidized, corrosion and so on.

2. Electrical parameter test: you can run the machine test, test the connected circuit, current, voltage, impedance and other aspects of the electrical parameters are normal, to determine the stability and reliability of the connector.

3. Reliability test: by placing in high temperature, high humidity, low temperature and other extreme environments, test the connector in such extreme environments, the ability to withstand, to determine the durability and reliability of the connector.

Third, the board-to-board connector failure maintenance strategy:

1. Regular cleaning: regular cleaning of the board-to-board connectors can avoid the problem of poor connector contact, to maintain contact stability.

2. Strengthen the inspection: In the process of use, regular inspection of the connector, found that wear and tear or damage timely replacement.

3. Reasonable use of the environment: in the use of the environment, try to avoid connectors and water, oil, impurities and other harmful substances in contact, to avoid oxidation corrosion and other problems.

Summary: the failure of the board-to-board connector will have a greater impact on the performance of electronic equipment, so the stability of its testing and maintenance is very important, in the use of the process should pay attention to the prevention of connector aging, physical damage and poor contact and other issues, while strengthening the inspection and maintenance to ensure that the connector's stability and reliability.
