    • A memory module having a packaging cover to encapsulate a board having multiple separate chips, which dynamically generating varying amounts heat. The packaging cover provides localized heat dissipation among the multiple separate memory chips. The separate chips are interconnected to the board via a set of solder balls. The packaging cover further provides a rigid encapsulation of the board and chips. In one embodiment, the memory module includes a thermally conductive substance displaced within the packaging cover to conduct heat from the separate chips to the packaging cover. In one embodiment, the packaging cover consists of a plastic material having a sheet of metal coupled to an interior surface of the packaging cover. In one embodiment, the packaging cover includes two separate covers, with a first cover having an insert pin, and a second cover having an insert receptacle to receive the insert pin. In an alternative embodiment, the first cover of the packaging cover includes a set of clip snaps to secure a coupling between the first cover and a second cover of the packaging cover.
    • 一种存储器模块,其具有封装封装封装封装的板,该板具有多个单独的芯片,其动态地产生变化量的热量。 包装盖在多个分离的存储器芯片之间提供局部散热。 单独的芯片通过一组焊球与板相互连接。 包装盖还提供了板和芯片的刚性封装。 在一个实施例中,存储器模块包括在封装盖内移动的导热物质,以将热量从分离的芯片传导到包装盖。 在一个实施例中,包装盖由具有耦合到包装盖的内表面的金属片的塑料材料组成。 在一个实施例中,包装盖包括两个单独的盖,第一盖具有插入销,第二盖具有用于接收插入销的插入件插座。 在替代实施例中,包装盖的第一盖包括一组夹扣,以固定第一盖和包装盖的第二盖之间的联接。
