Abstract

The invention discloses a circuit board testing tool which comprises an L-shaped pedestal and a lower die plate. The lower die plate is provided with a positioning groove, and the bottom of the positioning groove is provided with a first probe group that is connected with detection points at the lower surface of the circuit board. An upper die plate is also included, the upper die plate is provided with a second probe group that is connected with detection points at the upper surface of the circuit board, a connecting rod and guide rods, and a vertical plate is provided with a handle which can drive the connecting rod to move up and down and guiding blocks which are in up-and-down sliding cooperation with the guide rod. During detection, the circuit board is placed in the positioning groove, the positioning groove can ensure that the detection points at the detection points at the lower surface of the circuit board are correctly connected with the upper ends of first probe group, the handle pushes the upper die plate to move downwardly, the second probe group on the upper die plate is correctly connected with the detection points at the upper surface of the circuit board, the detection points of the circuit board are rapidly and accurately connected with a circuit board detector via the tool, and the circuit board detection speed is greatly improved.

Description

technical field [0001] The invention relates to a tooling, in particular to a circuit board testing tooling. Background technique [0002] In the production process of the car navigator, it is very important to test the circuit board in the car navigator. [0003] In the prior art, for circuit boards produced in small batches, the voltage and current between two measurement points on the circuit board are generally directly tested with a multimeter to determine whether the circuit board is qualified. This test method has the disadvantage of low test efficiency. [0004] For circuit boards produced in large quantities, in the prior art, a circuit board tester is generally used for automatic detection by software programs. The method of use is to connect each test point on the circuit board to the signal input terminal on the circuit board tester, run the test program in the computer, and the test result will be displayed on the computer monitor. If it is good, it will show O...
