摘要:
A stack-type semiconductor package includes a first semiconductor package upon which a second semiconductor package is stacked. A layer of a hardened, insulative material, e.g., a no-flow underfill (NUF) material, is disposed between, and mechanically couples the stacked first and second semiconductor packages. The NUF layer covers portions of the first semiconductor package, e.g., the semiconductor die and the substrate of the first semiconductor package, and solder balls of the second semiconductor package that are fused to the substrate of the first semiconductor package. The NUF material is applied onto the semiconductor die and substrate of the first semiconductor package before the second semiconductor package is stacked on the first semiconductor package, and substantially cures after the solder balls of the second semiconductor package are fused to the substrate of the first semiconductor package.
摘要:
A memory card including a printed circuit board having an electronic circuit device mounted thereto and at least one I/O pad disposed thereon. The printed circuit board and the electronic circuit device are at least partially encapsulated or covered by an encapsulant material which hardens into a body of the memory card, such body generally defining the outer appearance of the memory card. The I/O pads of the printed circuit board are exposed in the body. The body is formed to include one or more chamfers. Such chamfer(s) are sized and configured to minimize potential damage to the connection terminals or host socket of a device during the process of interfacing the memory card thereto.
