This article introduced a piezostack-driven jetting dispenser for a microelectronic packaging process. The dispenser had a compact displacement amplification module using two piezostack actuators for achieving compact design and maintaining high jetting performance and improving internal stress on the piezostack actuators. In this article, a working principle of a jetting dispenser configuration was introduced and was followed by the presentation of a displacement amplification mechanism using a cylindrical pivot. The dimensions of the amplification mechanism were determined based on a theoretical calculation of the system and the finite element analysis results. The internal stress of the piezostack and the output displacement of the dispenser were investigated at different operational frequencies. The experimental system with the jetting dispenser was manufactured, and the system performance was verified experimentally. For evaluating the performance, a mixed glycerol/ethanol was used for the dispensing fluid. The jetting system in this study achieved an ideal jetting performance at a jetting frequency of 350 Hz and a droplet diameter of 0.42 mm.

A novel hybrid excitation flux reversal machine (HEFRM) is developed. The machine has a simple reluctance rotor and a stator, which has both an ac armature winding and a dc field winding. The core on the surface of the pole arc at the centerline of the stator pole and the core on the outer surface of the stator yoke each have a slot along the rotating axis, where the field windings are placed. A permanent magnet (PM) with opposite polarity is placed respectively on each side of a slot in the same stator pole. In this paper, the working principle of the new HEFRM is introduced, the influence of magnetic pole parameters and armature parameters on motor performance are also analyzed, and genetic algorithm (GA) is used for multi-objective optimization of the torque characteristics. Finally, the HEFRM prototype is built, and its theoretical correctness is verified by the finite element analysis (FEA).

Based on the structure and working principle of our giant magnetostrictive actuator (GMA), the properties of the driving magnetic field were researched. A 3-D nonlinear magnetic field model of the GMA was established with the finite element analysis method, and the magnetic field distribution of the GMA was obtained with the software ANSYS. Then the 3-D model helped us to find the effects about the distribution of magnetic field of the GMA from the structure. The 3-D magnetic field finite element analysis model can give us a new tool of GMA design and analysis.
