Abstract

The invention discloses a wireless micro-secure digital memory card and a manufacturing method thereof. The wireless micro-secure digital memory card comprises a rectangular body, a circuit region and a finger lock region, wherein the circuit region is arranged in the middle of the body and extends to one short side edge of the body; the packaging thickness of the circuit region is 0.6-0.8mm and the circuit region is used for coating a memory module and a controller module; the finger lock region is horizontally arranged at the other short side edge of the body, the packaging thickness of the finger lock region is 0.9-1.1mm, the finger lock region raises out of the front of the body and is used for coating a three-dimensional micro radio frequency antenna of which the thickness is 110-185% of the packaging thickness of the circuit region; and the controller module is electrically connected with the memory module and the three-dimensional micro radio frequency antenna.

Description

technical field [0001] The present invention relates to a secure digital card (SD Card), and in particular to a micro secure digital card (Micro SD Card). Background technique [0002] A Secure Digital Memory Card (Secure Digital Memory Card, commonly referred to as SD Card) is a memory card that is widely used in portable devices, such as digital cameras, personal digital assistants, and multimedia players. The SD card technology is based on the Multi Media Card (MMC) format, but the SD card is slightly thicker than the MMC card. The SD card also has a higher data transfer speed, and the standard is constantly updated. Most SD cards have a write protection control on the side to prevent some data from being accidentally written, and a small number of SD cards even support digital rights management technology. The size of a general SD card is about 32mm×24mm×2.1mm, but it can be as thin as 1.4mm, which is the same as the MMC card. [0003] Micro Secure Digital Card (Micro...
