Problems solved by technology

This results in a large burden on the operator, leading to an increase in inspection time
In addition, since a detector is required in the structure of each workpiece, it is unrealistic to increase the number of detectors when inspecting multiple items.

Abstract

The invention provides an ultrasonic test device and an ultrasonic test method that can obtain stable test images. The ultrasonic test device comprises scanning units (1, 2) that can scan in a horizontal direction; a height adjusting unit (3) disposed in a vertical direction of the scanning units (1, 2); a support (5) arranged on the height adjusting unit (3); an ultrasonic detector (4) disposed on the support (5); a nozzle accessory (6) enabling water to flow from a nozzle to form continuous water flow from the ultrasonic detector (4) to a workpiece (9); and a gap adjusting unit (7) arranged on the height adjusting unit (3) or the support (5) and enabling the nozzle accessory (6) to move in a vertical direction.

Description

technical field [0001] The invention relates to an ultrasonic inspection device and an ultrasonic inspection method. Background technique [0002] Ultrasonic inspection equipment is a device that irradiates ultrasonic waves to the inspection object (hereinafter referred to as "workpiece"), and uses ultrasonic contact parts (hereinafter referred to as "probes") to receive reflected or transmitted ultrasonic waves and image them. [0003] For example, when the workpiece is an electronic device, it is necessary to detect fine defects, and an ultrasonic inspection device requires high resolution. The higher the frequency of the ultrasonic wave used by the ultrasonic inspection device, the higher the resolution can be obtained. On the other hand, the higher the frequency of the ultrasonic wave used, the greater the attenuation and the lower the S / N ratio. Water attenuates ultrasonic waves less than air, so a typical ultrasonic inspection device performs ultrasonic inspection in ...
