Abstract

The embodiment of the invention discloses a power panel testing method and device. By means of the power panel testing method and device, whether a power panel is qualified or not can be automatically judged through testing, and therefore the technical problem that a high error rate is caused by manual testing and accordingly testing efficiency is low is solved; the phenomenon that the power panel is damaged because input current is too large is avoided. The method includes the steps that current-limiting treatment is carried out on current input to the power panel according to a preset current-limiting value; after it is determined that a no-load voltage value output by the power panel having been subjected to current-limiting treatment satisfies a preset voltage value, a load voltage value output by the power panel is detected; after it is determined that the load voltage value satisfies a preset voltage value, the power panel is subjected to constant-current detection; after it is determined that a preset constant-current value is satisfied, discharging treatment is carried out on the power panel.

Description

technical field [0001] The invention relates to the technical field of integrated hardware, in particular to a method and device for testing a power board. Background technique [0002] The power board is an electronic component integrated board that supplies power to high-end electronic equipment. In addition to power supply, the power board also protects high-end electronic equipment from damage due to changes in external current and voltage, especially for current TVs. The power board is very important. However, before the power board is applied to the TV and packaged before production or after packaging, the performance of the power board needs to be tested or retested. The initial test is the first time the power board is powered on after the electronic components are installed. Test, retest is the test after the power board has been working for a long time. [0003] The current power board test method is usually to use a test stand, external voltage and ammeter to tes...
