Abstract
A flip-chip type quad flat package and a leadframe. The leadframe comprises a bump-connecting area and a non-connecting area. The maximum width of the bump-connecting area is larger than the width of the non-connecting area. A bump is limited to the bump-connecting area after performing a reflow process so that the bumps are prevented from collapsing, the manufacturing cost is reduced and the process is simplified.
