Ultrasonic investigation system, e.g. for checking electronic devices - transports objects sequentially to detector, and positions such that coupling fluid bath is between object and ultrasonic sensor

摘要

The system contains an ultrasonic transducer (1) which transmits ultrasound to an object (27) and receives the same ultrasonic waves reflected back from the object. A transport mechanism (11) continuously or sequentially conveys objects to an investigation position. A positioning arrangement (13) positions each object transported into the investigation position so that a coupling medium (13) is arranged between the object and the transducer. The objects are positioned in three dimensions relative to the transducer. USE/ADVANTAGE - E.g. for testing electronic devices, ICs, or material items. For efficient continuous or sequential testing of multiple objects.
