Abstract:
1. A conductive material supply method for ejecting electrically conductive material to a prescribed portion between a plurality of electrodes and solidifying it to thereby electrically connect said plurality of electrodes, comprising the steps of: transferring said electrically conductive material from a recessed portion to an interior space of a nozzle assembly with a first flow of gas of a first pressure introduced into the interior space of the nozzle assembly, said nozzle assembly includes a nozzle orifice through which said electrically conductive material is caused to pass and an interior space, the interior space being a substantially sealed space when said nozzle orifice is substantially closed by said electrically conductive material; bringing said interior space into communication with an exterior space to relieve the first pressure after said electrically conductive material has been transferred into said interior space; supplying a second flow of gas of a second pressure into said interior space; closing said nozzle orifice substantially with said electrically conductive material with supply of said second gas being continued, thereby achieving a pressure close to said second pressure in said interior space; and ejecting said electrically conductive material to said prescribed portion by the effect pressure created by the second gas.
