Research on the droplets formation of gallium based eutectic alloys based on the mode of pulse electromagnetic force

The uniform droplets of gallium based eutectic alloys have been widely used to develop the electronic packaging. Therefore, a droplet generator has been designed for formation uniform droplets in a controlled way, which entails important technological advantages over existing techniques. The results indicated that, the uniform droplets could be produced by continuous-ink-printing and drop-on-demand based on the mode of pulse electromagnetic force; compared with the droplets generator using one elastic diaphragm for producing water droplets by continuous-ink-printing, the metal droplets could be produced without using elastic diaphragm. Therefore, this work provides a useful parameter-selection approach for droplets production.
