Abstract: A process for applying an underfill material to a die is disclosed. A wafer is diced into a plurality of dies (without having any underfill film thereon) such that the dies have exposed bumps prior to an underfill process. Thus, the dies can be tested about their bump-sides because the bumps are entirely exposed for testing. The dies are then reconstituted bump-side up on a carrier panel in an array such that the dies are separated from each other by a gap. Underfill material (e.g., epoxy flux film) is then vacuum laminated to the carrier panel and the plurality of dies to encapsulate the dies. The underfill material is then cut between adjacent dies such that a portion of the underfill material covers at least one side edge of each die. The encapsulated dies are then removed from the carrier panel, thereby being prepared for a thermal bonding process to a substrate. Associated devices are provided.
