The invention relates to test equipment and a test fixture. The test fixture comprises a fixture body, a test probe, a fixing plate and a positioning piece used for placing a circuit board. The jig body is provided with a mounting part, and the test probe is arranged on the mounting part. The positioning piece is fixed to the fixing plate and movably arranged on the jig body in a penetrating mode so that the jig body can move relative to the fixing plate. When the circuit board is tested, the fixing plate is connected to the testing equipment body, the circuit board is placed on the positioning piece, and the fixing plate and the circuit board are kept still relative to the testing equipment body. If the positions of the jig body and the circuit board are deviated, the fixing plate and the circuit board are kept still, and the test probe and the jig body are driven to be finely adjusted as a whole. Thus, bending deformation of the test probe can be avoided, the service life of the test probe is effectively prolonged, and the stability of the test fixture is higher. In addition, fine tuning is carried out on the test fixture through the fine tuning device, and a traditional fine tuning frame is not needed, so that the test fixture is more convenient to install.
Description
technical field [0001] The invention relates to the technical field of circuit board testing, in particular to a testing device and a testing fixture. Background technique [0002] The circuit board is an important electronic component in electronic products. It is a support for electronic components and a provider of electrical connections for electronic components. In the manufacturing process of circuit boards, the test steps of circuit boards are a crucial link that directly affects the quality of shipped products. [0003] Generally, the circuit board is placed on the test fixture, and the probes of the test fixture are fine-tuned by the fine-tuning device. However, every time an adjustment is made, the probe of the test fixture will be deformed once. Under continuous bending and deformation, the probe of the test fixture will be easily broken, which will affect the service life of the test fixture. Contents of the invention [0004] Based on this, it is necessary t...
