METHOD AND APPARATUS FOR MANUFACTURING ENGINEERING BALLS WITH HIGH PRECISION AND HIGH YIELD

摘要

The present invention is discharged through the orifice from the spray tank and was ground by a vibration of the vibration device fall by to form a droplet, sikimyeo sphering, cooling, solidification to a busy A / sieseu blood package solder balls, such as a metal ball or a ceramic ball, etc. in the production of the engineering view, the engineering view size, the sphericity and surface roughness, such as precision manufacturing a and, in the manufacturing method of the yield significantly, which can increase high accuracy and high yield of the engineering view, and that the device It provides.; Manufacturing method of the main engineering view is disposed at a position that a liquid droplet so as to maximize the yield by eliminating defects due to adhesion of the liquid between which drops from the orifice (21a) fall, a predetermined positive or negative voltage is applied to the charger that 22 by passing the droplets that fall from the orifice (21a) through the step of applying a repulsive force to each other electrically by the electrostatic liquid falling downward and charging; The electrostatic downward by the electrically resisting drop between the contact to the deflector (23) is the predetermined voltage so as to partially fused further prevented by an electric force to magnetic force to to each other completely separate the liquid between the application of the falling and by under electrostatic charging It is characterized in that comprises the step of Correcting deflection between the droplet.
