Description

storage device

technical field

The present invention relates to a storage device, and more particularly to a storage device that can be matched with any casing and is easy to be modularized.

Background technique

With the development of computer technology, computers have become an integral part of most people's lives. Therefore, how to transfer files between different computers has become one of the problems in daily life. Due to the development of multimedia applications, the generated files are getting larger and larger. Although the 1.44MB disk is convenient to carry, the capacity is not enough. However, although the hard disk in the computer has a large capacity, it is inconvenient for users to carry it because of its large volume. In recent years, with the popularity of the Universal Serial Bus (USB) interface and the price reduction of Flash Memory, a storage device with large capacity, good compatibility, and portability has emerged. This storage device is called a flash disk drive or a USB flash disk (USB Flash Disk), which allows users to easily transfer data between different computers or storage devices.

FIG. 1 is a schematic structural diagram of a conventional storage device 100 . Please refer to FIG. 1 , the storage device 100 includes a circuit board 110 and a set of casings 120 . The circuit board 110 includes a docking portion 112, a control unit 114, and a flash memory 116, wherein the docking portion 112 is used as a connection port of a universal serial bus, and the control unit 114 is used to control the flash memory 116 to read and write data, and the flash memory 116 116 is used for storing data.

However, the docking portion 112 of the storage device 100 is directly fixed on the circuit board 110, and the circuit board 110 also has electronic components such as a control unit 114 and a flash memory 116. Therefore, the circuit board 110 must have a certain area and length to carry these electronic components. Because the circuit board 110 must have a certain area and length, the appearance volume of the storage module 100 is also limited and cannot be further reduced.

In view of this, there is another storage module for appearance volume. FIG. 2 is a schematic structural diagram of another conventional storage device 200 . Please refer to FIG. 2 , the device 200 includes a circuit board 210 , a docking portion 220 and a housing 230 . The circuit board 210 utilizes system packaging (System in Package, SiP) technology to integrate different types of electronic components on the circuit board with plastic, metal or ceramic materials to form a system-integrated packaging mode to protect the electronics in the packaging structure. element. Since the storage device 200 utilizes the system-in-package technology, the storage device 200 can be easily modularized and mass-produced.

However, since the system package seals all the electronic components in a package structure, once a certain component in the package structure is damaged, it cannot be repaired, but has to be discarded. On the other hand, in the manufacturing process of the packaging structure, once a process error occurs, it is difficult to rework. Therefore, the yield rate of the packaging process will directly affect the production cost of the storage module 200 .
