Problems solved by technology
When there are multiple functional board plugs and sockets connected, the functional board plugs and sockets of the same shape must be marked to distinguish them, otherwise it is easy to connect the functional boards and sockets incorrectly and cause failures
Due to the change of the circuit board under test in the production process, the applicable fixtures will often be changed along with it. At this time, the applicable fixtures and function cards of the circuit board often need to be reconnected. It is easy to make connection errors according to the artificial identification of the signs. It takes a lot of time and is not conducive to the improvement of production efficiency

The invention discloses a circuit board testing device, comprising a testing clamp, a socket, a wire plug, a functional card and a computer. An identification module is arranged on the computer. Each socket is connected with an identification circuit. Any identification circuit at least comprises an electrical parameter, which is different from that of other identification circuits. The inventionfurther discloses a method for the circuit board testing device to realize an adaptive positioning for the socket and the wire plug. In the invention, the problems of easy error and time consumption in the event of connecting the wire plug with the socket in the prior art are resolved; and the method has the advantages of accurate judgment, high efficiency and human resource saving.
Description
technical field [0001] The invention relates to a circuit board testing technology, in particular to a circuit board testing device and a method for realizing self-adaptive position of a socket and a line plug. Background technique [0002] With the development of science and technology, electronic products are widely used in people's daily life and industrial production. As an important part of electronic products, the performance of circuit boards directly determines the quality of the entire product to a large extent. The testing of circuit boards plays an important role. key role. [0003] During the circuit board testing process, the circuit board under test needs to be pressed into its applicable fixture to make it contact the test pin. It is indirectly connected with the function card through the fixture. Each test device is equipped with several kinds of function cards, and there are several kinds of function cards. Different function cards complete different func...
