发明名称 Method and apparatus for packaging flip chip bare die on printed circuit boards
摘要 An apparatus and a method for providing a fully protective package for a flip chip with a protective shield plate and an underfill encapsulant material. The apparatus comprises a semiconductor chip electrically connected by flip chip attachment to a substrate. A shield plate is placed in contact with a back surface of the semiconductor chip. An underfill encapsulant is disposed between the semiconductor chip and the shield plate, and the substrate. A glob top encapsulant may be applied about the periphery of the upper surface of the shield plate that extends to the substrate for additional protection and/or adherence.
