US Patent 7810705 Apparatus and method for supplying electrically conductive material

In a conductive material supply apparatus that can connect a small slider electrode and a wiring electrode on a flexure in a miniaturized magnetic head, electrically conductive material is supplied, with the aid of flow of nitrogen gas that is pressurized to a first pressure, into the interior of a nozzle assembly that defines an interior space having a nozzle orifice through which the electrically conductive material can pass. After the electrically conductive material has been supplied, the flow of the nitrogen gas is stopped, and the interior space is temporarily brought into communication with the exterior space thereby decreasing the pressure in the interior space. Thereafter, nitrogen gas maintained at a second pressure that is designed to be lower than the first pressure is supplied to the interior space, whereby the electrically conductive material is ejected to the exterior from the nozzle orifice by the effect of the second pressure.
