    • A small memory card includes a first substrate, a heat sink, a second substrate, at least one upper memory chip, at least one bottom memory chip and a glue layer. The heat sink is arranged between the first substrate and second substrate, and contacted with the metal, which are filled within the plurality of through holes, which formed between the first substrate and second substrate. And each of the upper memory chips and bottom memory chips are mounted on the first substrate and the second substrate, so that the heat of the upper and bottom memory chips may be traveled to the heat sink via the metal, which is filled within the through hole, then the heat will be dispersed. Thus, the small memory card of present invention having high function of disperses heat to promote its durability and lifetime effectively, the manufacturing processes must be simplified and the manufacturing cost must decrease also.
    • 小型存储卡包括第一基板,散热器,第二基板,至少一个上部存储器芯片,至少一个底部存储器芯片和胶合层。 散热器布置在第一基板和第二基板之间,并且与形成在第一基板和第二基板之间的多个通孔中填充的金属接触。 并且上部存储器芯片和底部存储器芯片中的每一个安装在第一基板和第二基板上,使得上部和下部存储器芯片的热量可以经由金属行进到散热器,该金属填充在通孔 孔,那么热会分散。 因此,本发明的小型存储卡具有高散热功能以有效提高其耐用性和寿命,因此制造工艺必须简化,制造成本也必须降低。
