METAL-WIRE FEEDING SYSTEM FOR LARGE CAPABILITY

摘要

The present invention relates to a high-capacity metal vapor supply, large metal vapor supply according to the invention a wire feeder unit for supplying the metal wire strands at the same time a number of 2 or more; Comprises a; and a cavity is formed in the upper surface boat to evaporate by heating the metal wire supplied from the wire feeder. In addition, the head and the nozzle is configured to be rotatable, in particular, the front cavity of the boat or PBN (Pyrolitic Boron Nitride) coating film is formed. According to ; the invention, the metal wires and metal deposition capacity is available it is possible to feed a number of strands simultaneously at least two, and further, when the feed of the metal wires need not to rotate the head and nozzle apart from each other by the boat, it is possible to prevent the metal is deposited on the nozzle.
