    摘要: A method for connecting electrical parts The method includes retaining a piece of metal within a nozzle, supplying inert gas to the nozzle, and irradiating the retained piece of metal with a light source while the supplied inert gas flows from apertures in the nozzle. The metal is melted by the light source. The method also includes ejecting the melted metal from the nozzle by the supplied inert gas onto electrical parts.
