    摘要: Electronic devices and methods for fabricating electronic devices are described. One embodiment includes a method comprising providing a first body and a second body, and electrically coupling the first body to the second body using a plurality of solder bumps, wherein a gap remains between the first body and the second body. The method also includes placing an underfill material into the gap between the first body and the second body, the underfill material comprising magnetic particles in a polymer composition. The method also includes curing the underfill material in the gap by applying a magnetic field powered by alternating current, to induce heat in the magnetic particles, wherein the heat in the magnetic particles heats the polymer composition, and the magnetic field is applied for a sufficient time to cure the polymer composition. Other embodiments are described and claimed.
