Article Design and Experiment of a Solder Paste Jetting System Driven by a Piezoelectric Stack

Dec 27, 2017 | Shoudong Gu, Xiaoyang Jiao, Jianfang Liu *, Zhigang Yang, Hai Jiang and Qingqing Lv

To compensate for the insufficiency and instability of solder paste dispensing and printing that are used in the SMT production process, a noncontact solder paste jetting system driven by a piezoelectric stack based on the principle of the nozzle-needle-system is introduced in this paper, in which a miniscule gap exists between the nozzle and needle during the jetting process....
