During FPC production, electrical performance testing is performed to ensure the quality and reliability of the FPC. To facilitate the positioning of the FPC during testing, a general-purpose sliding vacuum adsorption needle mold fixture is needed. However, in practical use, this fixture, which uses bottom adsorption, is prone to incomplete vacuum release and residual adsorption force during FPC positioning, making it difficult to pick up and place the substrate. This presents a drawback and makes it inconvenient for press-fitting and positioning the test board. Now, a novel universal sliding vacuum adsorption needle mold fixture for FPC testing is proposed to address the above-mentioned shortcomings. Utility Model Content

Furthermore, the bottom of the elastic element 23 is embedded and fixed to the bottom end inside the cavity 3; Specifically, such as Figures 1-5 As shown, when positioning the test plate, after placing the test plate at the top of the test platform 15, the vacuum tube installed at the connector 8 is used to evacuate air, so that a vacuum negative pressure is generated inside the evacuation chamber 13 and the evacuation hole 14. The mounting block 5 can slide down inside the cavity 3, and at the same time, it can drive the positioning foot 1 4 and positioning foot 2 9 to move down. The pressure head 6 can press and position the top two sides of the test plate on the top of the test platform 15. After the test is completed, the vacuum adsorption force is disconnected, and the elastic element 23 inside the cavity 3 can push the mounting block 5 up to reset the positioning foot 1 4 and positioning foot 2 9, and remove the test plate.

[0015] Two sets of threaded rods 18 are fixed at the top two ends of the mounting block 5, one in front and one behind. Adjustment grooves 16 are provided at the top two ends of the positioning foot 14 and positioning foot 29 respectively. Adjustment nuts 17 are provided at the top of the threaded rods 18.
