Influences of Atomizing Pressure on Preparation Processing of Lead-free Solder Powder

摘要：

An investigation on the melt delivery tube tip pressure and the effective atomizing efficiency of atomizing powder was carried out. The results show that all of melt delivery tube tip pressures are negative value in the atomization gas pressure range of 0.4~0.9 MPa,and they monotonously increase with increasing the atomizing pressure;when the atomizing pressure is higher than 0.7 MPa,the negative pressure of the melt delivery tube tip is slowly increasing with continuously increasing the atomizing pressure;the atomized powder possesses higher effective atomizing efficiency,more uniform size distribution,better sphericity and smoother surface at the atomizing pressure of 0.7 MPa and the pressure of the melt delivery tube tip of-39.44 kPa.
