Abstract

This research work focuses on optimal design of a high frequency jetting dispenser actuated by two piezoactuators. Firstly, a new configuration of the high frequency jetting dispenser for integrated circuits (ICs) fabricating is proposed. The optimal design of the jetting dispenser is then considered. In the optimal design, significant parts of the jetting dispenser such as the needle, the nozzle, the piezoactuators, the displacement amplification lever and return spring are considered. Firstly, the geometry of the nozzle and needle is optimally designed considering the maximum velocity of dispensed adhesive. The other significant parts of the jetting dispenser such as the piezoactuators, return springs and the amplifying lever are designed so that the jetting dispenser has a compact size and can work well at 1000Hz. In addition, the amplitude of needle motion can reach up to 0.3mm.
