Abstract
A wiring board manufacturing system, which is an electric wiring forming system, utilizes a magnesium alloy as a conductive metal for wiring pattern forming, and mixes and heats the magnesium alloy chips thereof in a cylinder (feeding unit) with a built-in screw, melting same into an alloy slurry of a thixotropic state. The alloy slurry thereof is discharged onto a board. The board is mounted on a work stage of a stage unit, which is driven and controlled in accordance with wiring pattern data inputted by a CAD or the like, and a wiring pattern is formed on the board with the discharged alloy. According to this system, it is possible to provide an electric wiring forming system, which does away with the effects on the environment resulting from waste liquid at manufacturing, enables manufacturing time to be shortened, and moreover, uses an inexpensive metallic material for forming a wiring pattern.
