Description
Technical Field
[0001] The utility model relates to the technical field of memory chip modules, and more particularly to a heat dissipation structure based on a micro-compressed solid-state storage hard disk module. Background Art
[0002] Three common module connection and assembly methods include embedded welding, connector slots, and board-to-board pin connections. Embedded welding refers to assembly onto a device via welding, such as eMMC and UFS. Its advantage is compactness and lightness, but its disadvantage is inconvenience in upgrading and replacing. Connector slots are connected via spring connectors and secured with screws and other structures, such as conventional memory modules and M.2 interface solid-state drives. The advantage is simple upgrading and replacement, but the spring pin structure and material limitations, such as defects in conductivity, equal length, impedance, and shielding protection, make them incapable of meeting higher frequency applications. Furthermore, the connector structure takes up space, limiting lightweight applications. With the development of small size and high density, the seismic stability of micro storage hard drive modules also tends to weaken, making them incapable of meeting the requirements of next-generation technology. Board-to-board pin connections were first used in CPUs, using high-precision, tiny board-to-board spring pins. Because the pins are extremely short and highly consistent, they are more suitable for high-frequency product applications. Among them, memory modules were the first to adopt board-to-board pin connection, giving birth to two types of compressed attached memory modules: LPCAMM2 (Low power DDRV CAMM2 module) and CAMM2 (Compression Attached Memory Module); however, board-to-board modules in the flash storage field are still in the exploratory stage, and standardized board-to-board pin connection modules and peripheral accessories such as onboard heat sinks have not yet been formed.
