Abstract
An electronic package is provided including a substrate, a device mounted on the substrate, and a solder member electrically coupling the device to the substrate. The package includes a dielectric material positioned substantially around the solder member which forms a physical connection between the substrate and the device. The volume of the solder member contracts during melting thereof to prevent failure of the physical connection and/or the electrical coupling between the substrate and the device.
