Description
Technical Field
[0001] The present invention belongs to the technical field of ultrasonic scanning detection, and particularly relates to an inverted water-jet ultrasonic detection device. Background Art
[0002] Ultrasonic scanning mainly uses an ultrasonic probe to emit ultrasonic pulses, which reach the workpiece to be detected through a coupling medium. Since the acoustic impedance of different materials is different, ultrasonic waves will generate reflected echoes and transmitted waves at the junction of various substances. The ultrasonic probe receives the reflected echoes and converts them into electrical signals, and the waveform or image is displayed through computer processing, so as to detect the internal structure and defects of the workpiece and determine the size and position of the defects.
[0003] In the existing ultrasonic scanning process of semiconductor power modules and electronic components, pure water is mainly used as the coupling medium, and the entire workpiece needs to be completely immersed in pure water for scanning detection. Since some parts of the workpiece to be detected cannot be in contact with water, it is necessary to design a corresponding waterproof carrier to ensure the sealing of the workpiece underwater.
[0004] The inventor found that there are at least the following technical problems in the existing scanning detection device: on the one hand, the pure water in which the workpiece is immersed needs to be filtered and replaced regularly to meet the use requirements, and the sealing performance of the waterproof carrier of the workpiece needs to be detected to prevent water leakage. If water leakage occurs, it is easy to damage the internal circuit of the workpiece, resulting in the scrapping of the workpiece; on the other hand, in the automated production process, the workpiece needs to be repeatedly flipped and clamped during loading and unloading, which directly affects the working efficiency of scanning detection.
[0005] Based on this, it is necessary to improve the defects existing in the prior art to overcome the deficiencies existing in practical applications. Summary of the Invention
