Description

Technical Field

[0001] The present invention belongs to the technical field of chip burning test, and more specifically, relates to a multi-channel Hall sensor burning test device and method. Background Art

[0002] The Hall chip is an integrated circuit based on the Hall effect, which can detect magnetic fields and convert them into electrical signals. When current passes through the Hall element in the Hall chip, if a magnetic field is applied perpendicular to the current direction, a potential difference will be generated in the transverse direction of the Hall element. This potential difference is the Hall voltage. The magnitude of the Hall voltage is directly related to the strength of the magnetic field and the magnitude of the current. Through the built-in circuit, the Hall chip can convert this voltage difference into a digital or analog signal output. Depending on the application scenario, the Hall sensor needs to burn a specific program into the built-in Hall chip, and needs to be tested to determine whether the Hall chip value after burning is qualified. Different types of Hall sensors generally have different numbers of channels, and different numbers of channels correspond to different numbers of Hall chips.

[0003] In the prior art, a Chinese patent with document number CN115420323A discloses a program burning and detection device for a Hall sensor, including a test frame, a burner, a detector, an industrial computer and a display screen arranged in the test frame. The test frame is provided with a workbench and a control console, and also includes a Y-axis assembly, a Z-axis assembly, a C-axis assembly, a moving axis, a test gear, an adapter, an adjustment mechanism, a cylinder and a pressing plate.

[0004] Although the program burning and detection device of the above-mentioned patent can improve the burning quality of the Hall sensor by testing the gear, it is still unable to solve the following problems existing in the existing Hall sensor burning and testing equipment: (1) it is unable to adapt to the burning and testing operations of multiple Hall sensors without switching workstations, which may result in low production efficiency; (2) it is necessary to tediously replace the carrier tooling and / or the electrical circuit of the program burning to achieve the burning and testing of Hall sensors of different sizes and different numbers of channels, resulting in low practicality.
