Patent ID: 7878065

Claim:
An ultrasonic inspection apparatus for inspecting integrated circuits for defects, operating by projecting ultrasonic waves from a transmitting transducer and receiving ultrasonic waves passing through or reflected from the integrated circuits by a receiving transducer to detect the defects, the ultrasonic inspection apparatus comprising: a container containing de-ionized water; at least one limiting member; a loading member; and a cover member; wherein the at least one limiting member, the loading member, and the cover member are disposed in the de-ionized water, and located between the transmitting transducer and the receiving transducer, the limiting member is connected to internal side walls of the container, the loading member is supported on the limiting member for loading the integrated circuits to be detected, the cover member is detachably disposed on the loading member for fixing the integrated circuits between the loading member and the cover member by a gravitational force of the cover member acting on the loading member.
