Life and loss of circuit board

Overview of the life of the circuit board

Circuit board is a key component of connecting various components in electronic equipment, and its life directly determines the reliability and performance of the equipment. The life of the circuit board refers to its normal work and maintain the performance of the time, during this period of time, the circuit board will not appear obvious poor connection, poor contact, plate cracking and plate deformation phenomenon. At present, the life of the circuit board is generally 5 to 10 years, but the specific life will be affected by a variety of factors.

The factors that affect the life of the circuit board

1. Environmental factors

Environmental factors are one of the main factors affecting the life of the circuit board. High temperature, humidity, dust, vibration, etc. will have a negative impact on the circuit board, accelerate the aging of the circuit board and reduce its life. Therefore, when using electronic equipment, try to avoid the use of harsh environments such as high temperature, humidity, dust and vibration, and regularly clean and maintain the equipment.

2. Electrical factors

Electrical factors, including voltage fluctuations, electrical noise and lightning strikes, will accelerate the aging of the circuit board and reduce its life. In order to extend the life of the circuit board, the appropriate power supply and protection circuit should be used to avoid too high or too low voltage, current and discharge.

3. Mechanical factors

Mechanical factors include mechanical vibration, mechanical shock and mechanical damage. Mechanical vibrations, shocks, and damage can cause the board to expand, contract, or break, affecting its connectivity and conductivity. Care should be taken to avoid mechanical collision and vibration when using electronic equipment, while maintaining the normal use of the equipment to avoid misoperation.

The method of extending the life of the circuit board

1. Maintain a dry, clean and safe environment

Electronic devices should be kept in a dry, ventilated environment with little humidity, away from dust, moisture and other contaminants. At the same time, the equipment should be cleaned and maintained regularly to prevent dust and impurities from entering the equipment, and keep the temperature appropriate. In addition, regular placement of electronic equipment is also conducive to extending the life of the equipment.

2. Use electronic devices wisely

Pay attention to the rational use of electronic equipment, avoid frequent switching on and off the power supply, avoid overload and short circuit, and avoid deliberately twisting or bending the wire and circuit board to avoid damage to the equipment, and promptly replace the の defective parts of the equipment.

3. Pay attention to maintenance and maintenance

In order to extend the life of the circuit board, it is also necessary to pay attention to the maintenance and maintenance of the equipment. Regular inspection and replacement of aging parts and electronic components, updating software and systems, and timely handling of electronic equipment failures are all important steps to extend the life of the board.

Circuit board is an important part of electronic equipment, its life and loss will have an important impact on the reliability and performance of the equipment. To extend the life of the circuit board, it is necessary to pay attention to the impact of environmental factors, electrical factors and mechanical factors on the circuit board, and take reasonable life extension methods and maintenance means. Only in this way can electronic equipment work well and create more value for people's lives and production.
