Description

technical field [0001] The present disclosure relates to the field of electronic technology, and in particular, to a method, device and related equipment for testing electronic and electrical components. Background technique [0002] With the increasing intelligence of vehicles, there are more and more low-voltage electronic and electrical components on-board, such as on-board radar, on-board camera, on-board instrument, on-board display, and electronic toll collection (ETC), among which There are also more and more water-cooled cooling methods for low-voltage electronic and electrical components in vehicles, such as water-cooled autonomous driving domain controllers. However, this water-cooled cooling method tends to make the condensed water climate more serious, so it is often necessary to conduct a condensed water climate test on the on-board low-voltage electrical and electronic components to verify the reliability of the on-board low-voltage electrical and electronic co...

Problems solved by technology

However, this water-cooled cooling method tends to make the occurrence of condensed water climate more serious, so it is often necessary to conduct condensed water climate tests on vehicle-mounted low-voltage electronic and electrical components to verify the reliability of vehicle-mounted low-voltage electronic and electrical components

[0003] At present, there are only condensate water climate test standards for vehicle-mounted high-voltage electronic and electrical components. For example, if the ISO19453-4 standard is based on the existing condensate water climate test standards for vehicle-mounted high-voltage electronic and electrical components, conduct condensate water climate tests for vehicle-mounted low-voltage electronic and electrical components. , the test effect is poor, and it is often difficult to accurately evaluate the anti-condensation water climate capability of vehicle-mounted low-voltage electronic and electrical components
