Abstract

The invention discloses an impedance test device, which comprises a test platform, a driving device, a plurality of test probes, an information processing device, a monitor, a universal meter, a relay module and a plurality of control keys. The test platform comprises a base for carrying a workpiece to be tested and a probe mounting frame which can be adjustably arranged above the base. The driving device is arranged on the base and is fixedly connected with the probe mounting frame to drive the probe mounting frame to move relative to the base. The plurality of the test probes are arranged on the probe mounting frame and are electrically connected with the relay module. The information processing device is arranged in the base for receiving a command, driving the driving device, the universal meter and the relay module to work, and performing the comparative analysis of test results. The impedance test device can automatically test the impedance of a plurality of impedance test points on the workpiece to be tested at one time, thereby effectively improving impedance test efficiency and test quality.

Description

technical field [0001] The invention relates to an impedance testing device, in particular to an impedance testing device capable of automatically performing multi-point impedance testing. Background technique [0002] In the field of electronic component manufacturing, before assembly and use of each electronic component, in order to enable it to have functions such as conduction and shielding, it is generally necessary to perform an impedance test on the electronic component to confirm whether the impedance value of the electronic component is within the specifications required by the customer. Usually, the customer will mark the test positions of several impedance measurement points on the blueprint of the electronic component, and mark a certain test point as a common point, and request to detect the impedance value between the remaining impedance test points and the common point. [0003] During the entire test process, the inspector needs to use a multimeter or an imp...
