Abstract
Time-pressure dispensing has been widely applied in IC packaging industry as a core technology. In such a process, the fluid is forced out of the syringe by the pressurized air and the model of the pressure in the syringe is difficult to develop because of the compressibility of the air. This paper presents the development of a model describing how the volume average pressure in the syringe varies by defining the unsteady time-pressure dispensing inflation process as a thermal insulation process for container of fixed volume. Additionally, a finite element simulation is performed to test the model by using FLUENT. The results show that the analytical solution and the simulation results match well. We also find that the face average pressure of a certain cross section varies greatly in the process, which implies the pressure in the syringe fluctuates very much.
