Abstract
The invention provides a new apparatus and method for forming thin metal parts of simple or intricate shape and depositing the same onto selected receiving surfaces. The parts may be in the form of wire leads which are bonded to the receiving surfaces. The invention consists in providing a hollow tool which includes a porous body with an exposed surface having a selected two-dimensional or three-dimensional geometry, immersing the surface of the porous body in a melt of a metal which will not wet the surface, pulling the tool away from the metal while applying a suction force to the porous body so that a portion of the melt will adhere to the surface, bringing the tool into contact with a receiving surface, and cooling the surface and removing the suction force so that the adhering portion of the melt will be deposited as a solid or partially solidified body onto the receiving surface. The deposited part will bond securely to the receiving surface if the latter is made of a material which is wetted by the melt.
