Vibratory treatment apparatus including a first receptacle arranged to receive media for vibratory treatment of the article, the first receptacle defining a first aperture; and a first valve positioned at the first aperture of the first receptacle, the first valve being arranged to allow passage of the article there through and to prevent the flow of media through the first aperture.

Example systems and methods for detecting movement of a sample subject to a polishing operation in a vibratory polisher. The system includes a sample holder to secure the sample to be polished. A housing supports a platen upon which the sample holder is placed. The platen allows for movement of the sample holder during a polishing operation as the sample holder traverses a polishing fluid distributed about the platen. One or more sensors are arranged about the housing, operable to monitor movement of the sample holder on the platen relative to the housing.

A vibropeening apparatus comprises a main frame, an enclosure receivable within the main frame, a rotary drive mechanism, and an article to be vibropeened. The enclosure defines an internal volume, the internal volume accommodating a vibropeening bed. The article is positioned within the internal volume, and the rotary drive mechanism is to configured to impart a rotary motion to the enclosure within the main frame.

A medium is accommodated in a container together with an electronic component body including an underlying electrode layer. The medium treats a surface of the underlying electrode layer while vibration is applied to the container. The medium is spherical or substantially spherical. The medium has a diameter not smaller than about 0.2 mm and not greater than about 2.0 mm. The medium contains tungsten.
