摘要

摘要: 为满足先进电子线路柔性、快速钎焊，设计开发了机械振动式焊滴喷射装置，该装置由电磁驱动、焊滴喷射、同轴供气、温度控制等模块组成。采用锡铅合金进行了喷射试验，在供气流量7.5 L/min~10 L/min范围内，可制备出球形度较好的颗粒；通过调节振动参数，实现了单颗均匀微滴的可控稳定喷射；本文试验条件下焊滴飞行平均速度约为2.43 m/s，有利于焊滴充分铺展以充分钎焊，为高质量的电子线路快速钎焊奠定了基础。

Abstract: In order to improve the flexibility and effectiveness of solder printing in the advanced microelectronic packaging, a micro droplet DOD generator driven by mechanical vibration was developed. It consisted of four components: the electromagnetic drive system, solder spray device, coaxial gas supply system and temperature control system. Micro droplets generating experiment was carried out with Sn-40wt. % Pb alloy. When the gas flow rate was between 7.5 L/min and 10 L/min, uniform solder particles with good sphericity were obtained. By adjusting the parameters of vibration, single droplet was generated stably. The experiment results also showed that the flying speed of droplet was about 2.43 m/s under the condition in present paper which was helpful for sufficient spread resulting in good printing quality. The research laid a foundation of high quality printing in the microelectronics packaging.
