A method for testing the hermetic seal of a packaged device, which includes: a package that delimits a device chamber; and a transducer device, which is arranged within the device chamber and generates an electrical signal indicating at least one physical quantity external to the package. The testing method includes the steps of: imposing a reference pressure in the device chamber; arranging the packaged device in a testing chamber in which a testing pressure is present, different from the reference pressure; and subsequently detecting possible pressure variations within the device chamber.

A for positioning a miniaturized piece includes a positioning structure that forms a first cavity designed to receive with play the miniaturized piece and a second cavity communicating with the first cavity. At least one electrical-contact terminal is provided facing the second cavity and is electrically coupleable to an electronic testing device designed to carry out an electrical test on the miniaturized piece. An actuator device causes a vibration of the positioning structure such that the vibration translates the miniaturized piece towards the second cavity until it penetrates at least in part into the second cavity.
