In this embodiment, the number of the to-be-measured areas is three, the three to-be-measured areas lead out signals to be measured through hole sites, the hole sites of the signals to be measured are distributed according to different functions realized by the board to be measured, the hole site spacing is fixed by 1.6mm, and the selected spring pins are located within the spacing to avoid adjacent signal contact.
In the test tool bottom plate provided by the utility model, the power supply processing part is provided with the stabilized voltage power supply to process so as to supply power to required elements. The information processing part processes the obtained information of the circuit board to be detected and the obtained button information and feeds the processed information back to the display screen for display. The button part is used as the input of man-machine interaction, and can display the information of each circuit board to be tested or turn pages and the like according to the requirements of testers. And the display screen displays the processed information in real time. The fastening piece compresses the circuit board to be tested or fixes the parts through the bronze column, the screw and the specific connector. The spring pins are welded on the bottom plate of the test fixture, the hole positions of the circuit board are in one-to-one correspondence with the hole positions of the bottom plate of the test fixture through the fastening piece, and the test hole positions are separated by a certain distance so as to avoid touching.
