Techniques of the automated control of amplitude and impedance of ultrasonic systems (US) of microwelding are offered as methods of registration of the reflected beam of the laser which allow to coordinate in the optimum the image elements of US systems in a range of frequencies of 50–120 kHz and to provide high quality and reproducibility of properties of the microwelded connections of high density (with a step up to 90 microns). The offered techniques are applicable for both operative and periodic diagnostics of US microwelding systems of the equipment of connecting terminals as they do not demand labour-consuming dismantling of the microwelding head and usage of the bench equipment.

 

Keywords: ultrasonic systems, microwelding, high density connections.
