Electronic devices and methods for fabricating electronic devices are described. One method includes providing a substrate with a die attach area, and forming a layer on the substrate outside of the die attach area. The layer may be formed from a fluoropolymer material. The method also includes coupling a die to the substrate in the die attach area, wherein a gap remains between the die and the die attach area. The method also includes placing an underfill material in the gap and adjacent to the layer on the substrate. Examples of fluoropolymer materials which may be used include polytetrafluoroethylene (PTFE) and perfluoroalkoxy polymer resin (PFA). Other embodiments are described and claimed.
