A curable underfill composition comprising an epoxy containing a curing agent component and a latent accelerator component. The accelerator component comprises a material which produces a resin with an exotherm below 300 J/g. Further, the combination may be utilized in an unfilled state which allows the epoxy to remain very viscous and thus increases the speed of the underfill process in comparison to filled epoxy compositions and epoxy compositions containing different accelerator components.
