A device for testing a circuit made up of a printed circuit board on which components, preferably dummy components, are assembled by the solder connections. An enclosure of the testing device subjects the circuit under test to a schedule of thermo-mechanical and/or vibration constraints. Bridges of electrical resistors, forms a hardware portion of the testing device. A software portion of the testing device sets a detection criterion representing damage to one or more solder connections and displays the results of the test. An input/output interface converts each electrical resistor measurement of the tested chains of solder connections into data for use the software portion. An adjusting component modifies the criterion for detecting damage to the solder connections. |
