Abstract
The invention discloses a universal test fixture for surface mounted technology (SMT)-based diode components, which comprises fore-and-aft sliding type positioning sliders, an elastic test probe module and a pull-out base plate. The fore-and-aft sliding type positioning sliders are composed of two sliders that are symmetrically arranged front and back. The two sliders are driven by screw-nut pairs arranged at the bottom thereof to move in opposite directions. The movable pull-out base plate is arranged close to the bottom. The left end of the movable pull-out base plate is connected with a reset device. On the pull-out base plate, the elastic test probe module is arranged between the two sliders. The elastic test probe module comprises a left test probe and a right test probe, wherein the two test probes are elastically flexible and are arranged right opposite to each other.
