摘要

As a core part of the electric vehicle motor controller, the integrated control board plays an important role in reliability and safety of the controller running. In order to ensure the stability of the performance of the new controller, this paper carried out a high accelerated life test for the relatively weak integrated control board, so as to quickly stimulate the weakness and defects of the PCBA in design and production process. Based on the discovered faults, we can improve and optimize the design and process as early as possible. As a result, we can reduce the failure rate of the product and finally improve its inherent reliability level. In addition, this test may also provide parameters for the following reliability tests such as high accelerated stress screening test, so the plan design proposed in this paper is of great value and significance.
