Abstract: A scanning acoustic microscope comprises a structure including a loading portion and a scanning portion, a transducer disposed in the scanning portion and operable to develop ultrasonic energy, and a controller. A driver is responsive to the controller and is capable of moving the transducer along a scan path with respect to a first plurality of parts disposed in the scanning portion as a second plurality of parts are being loaded into the loading portion.

Abstract: An improved scanning station and method for a tray-fed scanning acoustic microscope has a vacuum system which at least assists in immobilizing loosely held parts in the trays during insonification by an ultrasonic beam generator.

Abstract: A method and apparatus for non-destructive ultrasonic inspection in which a plurality of integrated circuits or other electronic components laid out in a fixed pattern on a liquid-permeable tray are moved along an inspection path through a scanning station. In the scanning station the electronic components are repetitively scanned by an ultrasonic beam from a transmitter/receiver moving rapidly back and forth across the inspection path; an ultrasonic coupling liquid (usually water) continuously flows along the beam path; the coupling liquid also flows along the surfaces of the electronic components opposite the beam path. The tray of electronic components is air dried as it emerges from the scanning station. Both reflected and "through" ultrasonic signals can be collected to disclose any anomalies present in the electronic components. A screen may be used to assure retention of the electronic components in the desired pattern on a tray.

Abstract: A controlled-immersion inspection mechanism gradually immerses a planar pattern of integrated circuits or other articles into a tank filled with water to a given level; across the tank there are two spaced parallel guide tracks along which two carriages, connected by a platform, move from an entry position above the water to an inspection position. In the inspection position the platform supports the articles, in an orderly array, for scanning inspection by a focussed energy beam, preferably an ultrasonic beam. A platform drive drives the platform between its entry and inspection positions. A mesh or other removable cover that permits water to flow but stabilizes article positions may cover the articles during immersion; the mesh is usually removed before scanning.
