Abstract
The quartz resonator comprises a vibrator (12) and a mounting (10). The electrodes (13) formed on the faces of the vibrator and on the mounting (11) are gold films. The vibrator (12) and the mounting (10) are pressed with the aid of a tool (15) whilst the electrodes (13, 11) are heated to a temperature of below their melting point. This heating causes a diffusion of the metals of the electrodes so as to establish the mechanical link and electrical connection of the electrodes between the vibrator and the mounting. <IMAGE>
