Purpose of environmental testing for electrical and electronic products

The purpose of environmental testing stems from the evaluation of the value of industrial products, not only the performance and performance is excellent, but also from the comprehensive evaluation of various other concepts, that is, under the harsh conditions of practice, function and performance. The level at which it can be ensured, and how long it can last, if it is difficult to change parts or repairs, these problems account for a large proportion of the pros and cons, and the ratio is flexible. For example, in the past, military equipment did not cost money, and the manufacture of excellent machines was the highest priority. Nowadays, the cost has been evaluated in the same direction as ordinary industrial products. Recently, with the globalization of trade, the conditions of transportation and operation have become more diverse. As a result, the requirements for the products are becoming more and more demanding, and the manufacturers who can handle these problems are the winners, able to survive, and thus how to improve quality, performance, trust, and low cost under the required conditions. Become a very important issue for manufacturers. These are not things that can be done overnight. It is necessary to properly consider the needs of users to develop a product plan, the manufacturing technology that can be manufactured, the data technology that can make or maintain the use of data, and the management of these proper use. , analysis techniques, etc., after these integrations are completed.

In order to further enhance the reliable method----environmental test, it takes a very important position. It is impossible to ensure quality without environmental testing. It is not an exaggeration. Environmental testing provides a defined, proven environmental impact to identify defects in structural design, components, data selection, and process in order to take appropriate action to improve the compliance of the intended application environment; It is to verify and assess the environmental adaptability of products, to test whether they can meet the requirements of specifications, technical standards or users, and as the basis for acceptance or rejection of production or bulk consumption; and to provide useful information for application, maintenance and logistics guarantees. Data information.

The purpose of the reliability test for electrical and electronic products is usually as follows:

1. In the development stage, it is used to expose defects in all aspects of the prototype product, and to evaluate the condition that the reliability of the product reaches the predetermined index;

2. The consumption phase provides information for monitoring the consumption process;

3. Carry out reliability verification or acceptance of the shaped products;

4. Exposure and analysis of product failure conditions under various environmental and stress conditions and related failure modes and failure mechanisms;

5. In order to improve product reliability, develop and improve reliability test plans to provide users with the basis for selecting products.
