Abstract
The utility model relates to a Hall sample fixture and a Hall effect tester for corrosion treatment, wherein the Hall sample fixture comprises: a bracket, which comprises a connected fixed frame and a tray; a pressing assembly, which comprises a mounting member and at least four pressure rods, wherein the mounting member is axially movably connected to the fixed frame, and at least four pressure rods are respectively hinged to the mounting member, and suction cups are arranged at the ends of the pressure rods; a driving assembly, which is used to drive the mounting member to move axially; when clamping the Hall sample, the Hall sample is placed on the tray, and four suction cups cover the upper surface of the metal electrode located at the four corners of the Hall sample, and the driving assembly drives the mounting member to drive at least four pressure rods to move downward, and the Hall sample is pressed onto the tray through the suction cups. The Hall sample fixture of the utility model can stably clamp the Hall sample, avoid the Hall sample from falling during the corrosion treatment process and affecting the corrosion effect, and can prevent the metal electrode from being corroded, thereby improving the accuracy and stability of the subsequent Hall effect test results.
