What are the effects of environmental factors on electronic products
Electronic products have a wide range of applications. The atmospheric environmental conditions during storage, transportation, and work are complex and changeable. In addition to the natural environment, factors affecting products include climate, machinery, radiation, biological and personnel conditions. The environmental requirements of a product must be formulated on the basis of various environmental and working conditions that it may actually encounter. For example, the requirements for temperature and humidity are determined by the climate and seasonal conditions of the area where the product is used; requirements for vibration, impact, etc. are related to the mechanical strength and transportation conditions that the product may be accompanied by; and whether there is chemical gas, salt spray, dust, etc. special requirements. Taking electronic measuring instruments as an example, the former Ministry of Electronics of my country issued standards for environmental requirements and test methods, and divided products into the following three groups according to environmental requirements.
Group I: The instrument used in a good environment should be operated carefully and only allowed to be subjected to slight vibration. Such instruments are precision instruments.
Group II: Instruments used in general environments are allowed to be subjected to general shocks. Instruments commonly used in laboratories generally fall into this category.
Group III: Instruments used in harsh environments are allowed to be subjected to greater vibrations and shocks during frequent handling and transportation. Instruments used outdoors and industrial sites fall into this category.
There are so many types of electronic products that it is impossible to put specific environmental requirements on each product. When designing and manufacturing, the environmental requirements can be determined by referring to the grouping principle of the instrument. Obviously, for general electronic products, reducing environmental requirements will make it difficult to adapt to more users and changes in environmental reliability.
