Abstract

A controlled volume of a liquid metal is dispensed from a ceramic capillary tube. A wetted film of the liquid metal is applied to the tip of the tube and the liquid metal is inserted into the interior of the tube. The tube contacts a receiving surface with the wetted film and ultrasonic energy is applied to the tube to dispense a small control volume with extreme precision.
