Problems solved by technology
[0002] The circuit board of the current intelligent pressure processor is mainly tested manually. Generally, the voltage and current between two measurement points on the circuit board are directly tested by a multimeter to judge whether the circuit board is qualified. This method has the disadvantage of low test efficiency.
For mass-produced circuit boards, a large number of people need to be invested in manual testing, and manual operations and judgment results are required. In the case of long-term work, due to the large amount of manual operations, the probability of quality problems is very high

The invention discloses a circuit board testing device and a circuit board testing method. The circuit board testing device comprises a test board; first-class circuit board access part which is arranged on the outer surface of the test board and is used for accessing a first-class circuit board to be detected; a second type circuit board access part which is arranged on the outer surface of the test board and is used for accessing a second type circuit board to be detected; a communication unit which is connected with the first type circuit board access part and the second type circuit board access part, sends a detection signal to the first type circuit board access part and the second type circuit board access part, and receives a feedback signal; a storage unit which is used for storing standard signal values of the first type of circuit board and the second type of circuit board; a comparison unit which is used for comparing the feedback signal received by the communication unit with the standard signal values of the first type of circuit board and the second type of circuit board stored by the storage unit to form a comparison result; and a display unit which is arranged on the outer surface of the test board and displays the comparison result.
Description
technical field [0001] The invention relates to the technical field of circuit board testing, in particular to a circuit board testing device and a circuit board testing method. Background technique [0002] The circuit board of the current intelligent pressure processor is mainly tested manually. Generally, the voltage and current between two measurement points on the circuit board are directly tested with a multimeter to judge whether the circuit board is qualified. This method has the disadvantage of low test efficiency. For mass-produced circuit boards, a large number of people need to be invested in manual testing, and manual operations and judgment results are required. In the case of long-term work, due to the large amount of manual operations, the probability of quality problems is very high. [0003] In the inspection of circuit boards, how to ensure that the equipment meets the requirements of users, reduce labor intensity, reduce labor costs, and improve productio...
