Description

technical field [0001] The invention belongs to the field of circuit board detection, in particular to circuit board detection equipment and a detection method. Background technique [0002] The sampling inspection of the circuit board before the manufacturer leaves the factory is generally to install the electronic components on the circuit board and then power on to detect the continuity of the circuit. This method not only detects the continuity of the circuit but also whether the electronic components are working normally. Therefore, there is an interference item of electronic components, and in order to save production costs, manufacturers generally remove the electronic components after completing the inspection and then solder them to the subsequent circuit board to be inspected for inspection, and each soldering and removal will use Electronic components are in a high-temperature environment to accelerate the damage of electronic components. Therefore, when a line is...

[0002] The sampling inspection of the circuit board before the manufacturer leaves the factory is generally to install the electronic components on the circuit board and then power on to detect the continuity of the circuit. This method not only detects the continuity of the circuit but also whether the electronic components are working normally. Therefore, there is an interference item of electronic components, and in order to save production costs, manufacturers generally remove the electronic components after completing the inspection and then solder them to the subsequent circuit board to be inspected for inspection, and each soldering and removal will use Electronic components are in a high-temperature environment to accelerate the damage of electronic components. Therefore, when a line is normally turned on, but the electronic components installed on the line are damaged, the test results will judge that the production of the circuit board of this batch is unqualified and reduce production. Efficiency increases the production cost, so it is necessary to provide a detection device that can detect the continuity of the circuit without installing electronic components
