Embodiment Construction

[0071] Please refer to FIG. 1A and FIG. 1B , which are diagrams and cross-sectional side views showing a small USB device 100 according to a first embodiment of the present invention. A USB device generally includes a printed circuit board assembly (PCB) 110 and a plastic case 150 fixed on the printed circuit board assembly 110 . Please refer to the upper part of FIG. 1A , the printed circuit board assembly 110 includes a printed circuit board (printed circuit board) 111, and the printed circuit board includes a printed circuit board handle portion 112 at the rear of the printed circuit board 111 end, and a printed circuit board plug portion 114 at the front end of the printed circuit board 111. The printed circuit board 111 is actually a planar substrate with two opposite surfaces, namely an upper (first) surface 116 and a lower (second) surface 118 . Formed on the upper surface 116 of the plug portion 114 are four metal contacts 120 shaped and arranged in accordance with a ...

Abstract

The invention relates to a small universal serial bus device which comprises a printed circuit board component, a plurality of conducting wires and a single molding outer casing. The printed circuit board component comprises: a printed circuit board which comprises a printed circuit board handle part and a printed circuit board plug part and is provided with a first surface and a second surface opposite to each other; a plurality of metal contact points which are arranged on the first surface of the printed circuit board plug part; at least a driven element which is fixed on the second surface of the printed circuit board handle part; at least an integrated circuit grain which is not packaged and is fixed on the second surface of the printed circuit board handle part. Therefore, the small universal serial bus device has uniform thickness.

Description

technical field [0001] The present invention relates to a portable electronic device, in particular to a portable electronic device utilizing the Universal-Serial-Bus (USB) specification. Background technique [0002] Due to the rapid growth of technological development in various fields, it is possible to make a small, portable memory card with a large capacity after being aggregated. Flash memory technology, such as those using Electrically-Erasable Programmable Read-Only Memory (EEPROM) technology to manufacture chips that can store 125Mb or more, small flash memory cards are designed It has a connector that can be inserted into a specific card reader, for example, providing a compressed flash memory card (Compact Flash, CF), a secure digital memory card (Secure-Digital, SD), a memory stick (Memory Stick, MS) , or other standardized formats used. [0003] In recent years, flash memory cards have been sold that include a USB connector, which allows the card to be plugged...
