The conductive light shield for a probe station of the present invention for cable connection pin clips includes a conductive shield body and a light-absorbing layer. The conductive shield body covers the outside of the pin clip on the probe station. The conductive shield body includes a top wall and side walls extending downwards from the edge of the top wall, with one end of the side wall away from the top wall contacting the probe station. The conductive shield body provides electrostatic shielding and optical protection, ensuring that the pin clip is protected from electrostatic discharge and stray light interference during testing, thereby improving testing accuracy and stability. Cable openings are provided on the side walls to accommodate the cable layout between the pin clip and the testing machine, ensuring that the cable can pass smoothly and maintain a normal connection with the testing system. The light-absorbing layer is disposed on the surface of the conductive shield body. The organic carbon black coating has good light absorption properties and can effectively absorb stray light from the environment, reducing interference from light reflection on the optical alignment system.
