Embodiment Construction

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0024] (structure)

[0025] figure 1 It is a schematic diagram showing the cross-sectional structure of the nozzle head in the embodiment viewed from the front. A supply chamber 102 storing a metal material as a raw material is provided on the nozzle head 100 . A heating mechanism 141 is provided around the supply chamber 102, and heats and melts the metal material above its melting point. In addition, the nozzle head 100 includes a nozzle 103 that ejects molten metal. Furthermore, it is provided with the pressure chamber 104 which communicates with the nozzle 103 and generates the pressure for ejecting molten metal material. The supply chamber 102 and the pressure chamber 104 are separated by a piston 120 . Therefore, the pressure chamber 104 and the supply chamber 102 are simultaneously heated from the outside by the heating mechanism 141 . Furthermore, the upp...

Abstract

The invention provides a nozzle head, a metal particle manufacturing device using the nozzle head and a metal particle manufacturing method. In a nozzle head for jetting molten metal material, the temperature distribution of the molten metal material is increased, so that the deviation or the dimension of the composition of the jetted metal material is not stable. The nozzle head comprises a nozzle jetting molten metal, a pressure chamber used for generating the pressure for jetting the molten metal via the nozzle, a supply chamber supplying the molten metal to the pressure chamber, a piston located at the position striding the pressure chamber and the supply chamber to transmit the pressure, and a pressurizing part making the piston movable. The nozzle head comprises a first heating mechanism heating the pressure chamber and the supply chamber and a second heating mechanism heating the piston. The invention also provides the metal particle manufacturing device using the nozzle head.

Description

technical field [0001] The present invention relates to a nozzle head for ejecting a liquid material, and an apparatus and method using the nozzle head. In particular, it relates to a nozzle head for producing particles having a uniform size by ejecting a molten metal material, and an apparatus and method for using the nozzle head. Background technique [0002] Uniform particles with a uniform shape are widely used in various fields including electrical products regardless of their material. For example, uniform particles of silica produced by a sol-gel method are widely used as particles for ensuring the gap between glass plates with high precision in liquid crystal panels. [0003] And, in order to mount the semiconductor IC package on the circuit board, solder particles are used in the electrode portion. Since the electrodes of the semiconductor IC package are arranged in a grid pattern, this kind of solder particles is called a ball grid array. [0004] As a method fo...
