摘要：
An underfill injection mold includes an inner surface defining a cavity to receive injected underfill substantially between a first substrate and a second substrate. The cavity includes convex, curvilinear sidewalls to define a concave, curvilinear underfill fillet of the injected underfill. In an example, dimensions of the inner surface that define the underfill fillet are based upon a finite element analysis of the underfill.
