Abstract: In electronics packaging, one of the key processes is dispensing fluid materials, such as adhesive, epoxy, encapsulant, onto substrates or printed circuit boards for the purpose of surface ...

Abstract: Fluid dispensing is a process widely used in electronics packaging manufacturing, by which fluid materials are delivered in a controlled manner for the purpose of bonding, sealing, coating, or ...

Abstract: Piezoelectric actuators (PEAs) have been widely used in nanopositioning applications due to their high stiffness, fast responses, and large actuating forces. However, the existence of nonlinearities such as hysteresis can ...

Abstract: Tissue regeneration with scaffolds has proven promising for the repair of damaged tissues or organs. Dispensing-based printing techniques for scaffold fabrication have drawn considerable attention due to their ability to ...

Abstract: Basic flow relationships are developed for three typical non-Newtonian lubricant models: the pseudo-plastic model, the circular viscoplastic model, and the ideal viscoplastic model. It is found ...

Abstract: The Reynolds equations for viscoplastic lubricants can be quite complex, involving multiple branches which depend on the form of the boundary conditions invoked in their development. Methods of ...

Abstract: A metalforming inlet zone analysis is developed for a viscoplastic lubricant that is Newtonian below some critical stress level at which it shears plastically. The analysis includes the effects ...

Abstract: This paper examines the almost-sure asymptotic stability condition of a linear multiplicative stochastic system, which is a linear part of a co-dimension two-bifurcation system that is on a ...

Abstract: Surface-degrading polymers have been widely used to fabricate scaffolds with the mechanical properties appropriate for tissue regeneration/repair. During their surface degradation, the material properties of polymers remain ...
