A device for positioning an electronic test head with respect to a manipulator for manipulating electronic components, in particular integrated circuits, includes a supporting structure fitted to a base, a frame to which the electronic head is connectable, and an actuating assembly for moving the frame with respect to the supporting structure; the base has a number of shoes, e.g. compressed-air shoes, cooperating with a supporting surface; when idle, the base rests on the supporting surface by means of the shoes; when compressed air is supplied to the shoes, the shoes are raised vertically by a few microns with respect to the supporting surface; in which condition, the device is supported hydrostatically and substantially weightlessly with respect to the supporting surface, and the whole device can easily be moved manually by the operator in any direction parallel to the supporting surface.
