(57) ABSTRACT
An ultrasonic inspection apparatus includes a container containing de-ionized water, at least one limiting member, a loading member, and a cover member. The at least one limiting member, the loading member, and the cover member are disposed in the de-ionized water and between the transmitting transducer and the receiving transducer. The limiting member is supported on the limiting member for loading the integrated circuits to be inspected. The cover member is detachably disposed on the loading member for holding the integrated circuits by a gravitational force of the cover member acting on the loading member.
