Problems solved by technology
[0003] In order to ensure that the performance of the circuit board meets the standard, after the circuit board is processed, it is necessary to use the test system to test the circuit board to ensure the connection of the circuit board. The traditional test system only tests the circuit connection of the circuit board, while The circuit boards driven by DC motors have a reduced service life due to their use environment, so testing only for the circuit connections of the circuit boards cannot meet the standards of circuit boards driven by DC motors, and it is difficult to test the circuit boards driven by a certain batch of DC motors. Whether the service life of the board meets the standard is tested
