The plant for production of powders by
Centrifugal Ultrasonic Atomisation (CUA)

This technology is used for production of powders with the ideal spherical shape, narrow particle-size distribution and low contents of oxygen for an electron technology: Sn61Pb39, Sn63Pb35Ag2, etc. Such plant is applied in England, USA, Japan and China for production of solder powders at preparation of soldering pastes used in surface-mount technology of electronic components.
