Embodiment Construction

[0044] The present invention will be described in detail below in conjunction with various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention. For example, the following will take UFD (USB Flash Drive) 3.0 as an example to illustrate the Universal Serial Bus device of the present invention, but those of ordinary skill in the art can easily think that the present invention is also applicable to UFD1.0, UFD2. 0 and other earlier versions of USB flash drives, it can also be applied to other types of USB drives, such as USB wireless network drives, etc.

[0045] Such as Figure 1 to Figure 3 As shown, in this embodiment, the USB device 100 includes a circuit board assembly and a plastic casing 20 . The circuit board assembly includes a printed cir...

Abstract

The invention provides a universal serial bus device which comprises a circuit board assembly and a plastic package casing. The circuit board assembly comprises a circuit board, a plurality of conducting terminals and at least one integrated circuit chip. The circuit board is provided with a front end, a back end, a first surface and a second surface, wherein the first surface and the second surface are opposite, and the first surface is provided with a plurality of metal contact pads. The plurality of conducting terminals are arranged on at least parts of the plurality of metal contact pads. The integrated circuit chip is arranged on the second surface of the circuit board. The plastic package casing is at least arranged on the second surface of the circuit board and packages the integrated circuit chip. Due to the fact that the conducting terminals can be directly arranged on the metal contact pads, slotting on the circuit board is not required, the universal serial bus device is simple in structure, and the reduction of the production and manufacture cost is facilitated.

Description

technical field [0001] The present invention relates to a universal serial bus (USB) device, in particular to a USB flash drive. [0002] The present invention also relates to a method of manufacturing the above-mentioned USB device. Background technique [0003] Universal Serial Bus (Universal Serial Bus, USB) is a serial bus standard that connects computer systems and external devices. It is also a technical specification for input and output interfaces. Photographic equipment, digital TV (set-top box), game consoles and other related fields. [0004] Since the USB1.0 version was launched in 1996, it has experienced USB1.1, USB2.0 versions, and has now developed to USB3.0 version. The main difference between the versions is the maximum transfer rate. The earliest version of USB1.0 has a transmission rate of 1.5Mbps (192KB / s), and is mainly used for human-machine interface devices, such as keyboards, mice, and joysticks. USB1.1, which was launched in 1998, has a tra...
