Electronic product development is a complex process that requires time, and reliability testing is crucial to the durability of the product. For example, reliability testing of temperature and humidity can demonstrate the state of electronic products under extreme high and low temperatures, and this type of testing can verify the impact of the climate on electronic products.
Electronic products refer to relevant products that are manufactured using electronic technology with electrical energy as the working basis, including electric/electrical equipment and microelectronic instruments, equipment and systems. Electronic products are widely used in national defense, various sectors of the national economy and people's lives.
In general, electronics reliability is related to lifespan. The longer the average lifespan of electronic components, the higher the reliability of electronic products is often. However, reliability and lifespan are not the same concept. High reliability of electronic products does not mean long lifespan, and a long lifespan does not necessarily result in high reliability. All of these aspects are related to usage requirements.
There are several factors that mainly impact electronic product reliability:
Electronic components are greatly affected by environmental factors during operation, such as temperature, humidity, salt spray, pressure, altitude, atmospheric pollution particles, etc., all of which can impact the normal operation of electronic components, causing decreased electrical performance or even damage to components, leading to malfunctions.
The mechanical structure of electronic products should meet the requirements of the operating conditions. Strong mechanical vibration or collision can cause the equipment to suffer from mechanical structural damage deformation, or even lead to physical damage or failure of electronic components, resulting in abnormal operation of electronic products.
Electromagnetic waves are ubiquitous in the environment, and electronic products constantly come into contact with electromagnetic signals during operation. Under the influence of electromagnetic signals, the noise of electronic circuits will increase, and the stability will decrease. If the interference is severe, it may even cause equipment failure or endanger personal safety.
In addition to the quality of electronic components and design factors, the manufacturing process will also directly affect the reliability of products. Different assembly processes will directly impact the firmness of the connections, sealing, and resistance to environmental corrosion, which will further affect the quality and reliability of electronic products.
In fact, in addition to the use of reliability, the inherent reliability and environmental adaptability of electronic products are determined by the design and manufacturing process. That is to say, after electronic products are manufactured, the main reliability indicators of electronic products are fixed and unchangeable. External environments are only a test of reliability. Therefore, the key to improving electronics reliability lies in improving design and manufacturing quality.
