After the new design product is manufactured according to the self-designed materials, it is necessary to test the product design information according to the technical requirements. After the sample test is passed, the design data can be finalized and transferred to the new product trial production.
Two：production stereotype test
For products designed or copied by themselves, the stereotypes are still in the stage of trial production of new products. In order to check whether the product drawings, process materials, etc. are correct, whether the relevant process equipment, processing methods, etc. can ensure stable batch production, Conditions require testing of the entire project. After passing the test, the batch can be produced.
For the batch production of products, at regular intervals, in order to assess the stability of the quality of the product in batch production, or after an important modification in the structure, manufacturing process, and material substitution of a product, To meet the requirements of technical conditions, it is necessary to carry out tests on all specified items. The interval between the type tests is determined by the technical conditions of the product. For example, every three months, six months, one year, one and a half years.
The acceptance test is an inspection process after the assembly of electrical products is completed. After each batch of products put into production is assembled, the factory inspection department conducts tests according to the requirements specified in the technical conditions. Regarding the content of the acceptance test, there are different requirements for different products.
(1) Environmental stress screening
A series of tests conducted under ambient stress to expose defective components and manufacturing defects for correction.
(2) Reliability research growth test
A series of tests conducted to expose defects and verify corrective actions can prevent repeated occurrence of these defects in the product.
(3) Reliability identification test
Samples of production technology status approved by government representatives are tested under specified conditions to determine whether the product meets the specified reliability requirements and as a basis for approval of production.
(4) Production reliability acceptance test
A test performed by a government representative on a product that has been submitted or submitted under specified conditions to determine whether the product of the manufacturer meets the specified reliability requirements.
Six： engineering research, analytical testing
This test includes two main aspects of process testing and research testing of structural changes. Its purpose and tasks are: to analyze the quality problems of the batch products; to formulate new design structures, to improve the existing design structure; to determine the possibility of material substitution or adoption of new processes and technologies; Whether special requirements other than technical conditions are met.
