3. Creation description (1) [Technical field to which the new type belongs] This creation relates to a storage device, and in particular to a small and portable universal serial bus (USB) storage device. Grain 4 short [previous technology] Discs are discreetly portable data storage media including u40 magnetic discs, & recordable optical discs' memory cards and card readers, as well as common μ " surface flash drives, Among them, the flash drive is the most practical, because it: write and plug and play, is more suitable for mobile e-commerce: and; storage and application 'so its market share is quite high, only this type of market : Yes, the competition is also very fierce. "Every manufacturer has made every effort to develop better and more useful products to meet the market needs." Please refer to the figure below. Its appearance mainly includes one The shell is. The case 包覆 is covered with a plurality of memories and a circuit board (not shown) that cooperates with it. This circuit j is connected to a USB connector 12 which is exposed at the end of the casing 10 And the USB connector 12 can be covered with a cover 14 which is a housing 1 fitted together. When in use, the cover 14 can be detached from the USB connector U and the connector 12 can be inserted into an electronic device. Corresponding slot. In, you can transfer and store. 8. However, the overall length of today ’s flash drives may vary depending on the design. The length of the blade is in the range of millimeters (mm) to 60mm, but its width is at least over ^ Ι4πιηη. Its volume is huge because of the casing There are standard flash memories with a length of about 20mm and a width of about 12mm, so that the width of the USB flash drive case is between 14mm and 16 dragons.

4. Explanation (2) In addition, because the width of the USB connector itself is small and fat, it should not cover the load, which makes the appearance of the USB flash drive convenient. In order to solve the above problems, a serial storage (USB) storage # is proposed to solve the above problems. [New Content] The main purpose of this creation is to save the installation! It is said that the technology of “supplied-multipurpose tandem bus storage technology” which has been used to package the soil on the earth ’s plate is significantly different from the conventional one. Make the type of the universal serial bus of the storage device to increase the portability and increase the readability of the universal serial bus. Another purpose of this type of storage is to provide a storage device, so The storage device volume is greatly reduced plus 0. Another purpose of this creation is to provide a storage device, so the application of the storage device volume is greatly reduced. According to this creation, a universal serial bus (USB) storage device includes a substrate on which a circuit layer, a universal serial bus interface, multiple passive components, and at least one memory chip are provided. This circuit layer is connected to the universal serial bus interface, and these passive components and the electronic chip are electrically connected to the circuit layer, and then a memory layer is encapsulated by a packaging layer. Cover and expose the interface of this universal serial bus. The detailed description will be given below with specific examples in conjunction with the attached drawings. Volume M282296 4. Creation Instructions (3) It is easy to understand the purpose, technical content, characteristics and Its achieved effect. [Embodiment] This creation is a universal serial bus (USB) storage device, which can be stored through a USB transmission connector of a computer. Please refer to the second and third figures. The storage device includes a substrate. 20. The substrate is a glass fiber board (FR4) or a resin-coated copper foil (FR5). The substrate 20 has a first surface 22 and a second surface 24. Here, the first surface 22 and the second surface • 4 is provided with a -circuit layer 26, and a universal serial bus interface 28 is provided on the first surface 此. This universal serial bus interface 28 is electrically connected to the circuit layer 26, and on the first surface 22 A plurality of passive components 30 are set on the surface using a Surface Moment (SMT) method. These passive components 30 can be selected from resistors, capacitors, inductors, or transformers, and these passive components 30 and circuit layers 26 are arranged. Electrically connected, and a memory chip 32 is provided on the first surface and the first surface 24 respectively, and the wafer 32 is electrically connected to the circuit layer 26 on the substrate 20 by wire bonding or flip-chip. Then, the wafer 32 is connected. , Passive element 30 and circuit layer 26 The encapsulation layer 34 made of epoxy resin grease. The universal serial bus interface 28 is not covered by the encapsulation layer 34 and is exposed. Finally, the packaged device is enclosed in a casing. 36, and the universal serial bus interface 28 is externally connected to the computer's USB transmission connector to provide storage data. In addition, the universal serial bus interface 28 does not have a traditional USB protective shell. The volume occupied by the serial bus interface 28 is reduced.

Page 7 M282296 IV. Creative Instructions (4) '-So this universal serial bus (USB) storage device, by setting the memory chip directly on the substrate 20, is different from the conventional technology of packaging. The memory is set on the substrate, so that the volume is reduced from the original length of about 40 mm (mm) and a width of at least 14 mm to a length of about 32 mm and a width of about 32 mm. In addition, this universal serial bus interface 28 and Without the traditional USB protective shell, the volume of this storage device is further reduced. Therefore, the present invention greatly reduces the volume, thereby increasing the convenience of carrying, and because the volume of the storage device is greatly reduced, this type of storage device has more applicability Yuanhua ^ If the appearance can be changed, the driver can be creative, it can be rectangular, mobile phone, egg or arc, or it can be compatible with the current flash memory card or memory card ^ Sa ^ lgltal 'SD ) The card is 32mm in length and is stored in a mini portable box. The embodiment described above is only a preferred embodiment of this creation. By understanding the characteristics of the second and the second editions, the purpose is to enable those skilled in the art to have the scope. Xinggu is based on this, and is not intended to limit the implementation of this creation. Patent scope: 1 Should be included in this creation application
