Problems solved by technology
For the automatic power-on control of batch test fixtures, the test base plate is used to cooperate with the external manual switch. After the module is manually pressed, the operator presses the power switch and cooperates with the power-on control system to ensure the normal power-on of the module, so as to solve the " The power supply jitters when the power is turned on, and it is impossible to ensure that the module is fully in contact with the test thimble and then power on" problem
However, this technical solution increases the manual actions of the operator, takes a long time to test, and is prone to misoperation, which is not conducive to production use

Description
technical field [0001] The present application relates to the technical field of power supply module test control, and more specifically, to an automatic power-on control method and device for batch testing of complex power supply modules. Background technique [0002] With the development of technology informatization and technology, integrated circuits are becoming more and more complex, and the power supply required by the chip is becoming more and more detailed. In order to ensure the normal startup of the chip, there are not only different voltage requirements for the peripheral power supply circuit, but also There are requirements for timing of different voltages and IO ports. For example, for some modules, the module itself needs multiple peripheral power supplies with different voltage values, and has clear requirements for the power-on sequence and external enable signals. This poses certain challenges to the power control of the module test board and test fixture. ...
