A Study of Reaction Viscosity Changes in Electronic Packaging with Different Nanoparticle Strengthened Epoxy Matrices
Abstract:
In this paper, the effects of strengthening epoxy matrices with nanopowders are discussed. Investigate the changes of reaction viscosities after adding different hardeners, nanoparticles and diluents to the polymer matrices. Analyze the applications to the automatic electronic packaging. The results show that different species in the curing reaction systems of epoxy will affect flow stabilities. Reaction viscositiesare affected primarily by the choice of hardeners. Nanoparticles will increase system viscosities and shorten matrix resin gel time. Adding diluents will help spread the powders and material flows in the systems, but is relatively not good for stability.
