Electric appliance reliability tester and test method

Abstract

The invention discloses an electric appliance reliability tester and a test method. The tester comprises a clock generation unit used for outputting a clock signal, a plurality of multipath load scanning switching driving units and a power supply unit, wherein the input ends of the multipath load scanning switching driving units are connected with the output end of the clock generation unit, and the multipath load scanning switching driving units are used for receiving clock signals output by the clock generation unit; the working states of a plurality of to-be-tested electric appliances are controlled according to the clock signals, and the load output ends of the to-be-tested electric appliances are connected with a load through the electric appliance reliability tester; and the power supply unit is used for providing a working power supply for the electric appliance reliability tester. According to the invention, a plurality of to-be-tested electric appliances do not need to be independently provided with a test device in the test process so that the cost of an electronic and electrical product in an environment reliability test is effectively reduced, and the test times of completing the whole machine environment reliability test are indirectly improved. The tester can be widely applied to the technical field of electronic tests.

Description

technical field [0001] The invention relates to the technical field of electronic testing, in particular to a testing device and testing method for electrical reliability. Background technique [0002] With the use of new materials and new technologies, the performance of the product has been rapidly improved, the complexity of the product has increased correspondingly, and the number of failures has also increased accordingly. The environmental reliability test of electronic and electrical products is to simulate the condition of the product in the use environment through various environmental test equipment to verify whether the product meets the expected quality goals of research and development, design and manufacturing. However, most electronic and electrical products are relatively large in size and involve many controllers, such as refrigerators and air conditioners. To conduct tests, the investment in laboratory resources and power investment are very huge, so most ...

Problems solved by technology

However, most electronic and electrical products are relatively large in size and involve many controllers, such as refrigerators and air conditioners. Experiments are conducted, so that the investment in laboratory resources and power investment are very huge, so most companies cannot conduct sufficient environmental reliability tests for the whole machine
