Portable storage device with fingerprint identification function

The present invention relates to a portable storage device, and more particularly to a portable storage device with fingerprint recognition function.

As technology advances, portable storage devices, which typically contain personal data, are stored internally. Generally, in order to prevent other people from obtaining personal information, a software is used to lock the data in the portable storage device, and a predetermined password is required to access the digital information in the portable storage device. However, this method of entering a password is still very easy because other people obtain the password through other means, so that the personal data is obtained by others.

Therefore, although a fingerprint identifier is developed, the fingerprint identifier is disposed on the portable storage device to identify the biometric information of the correct user. However, conventional fingerprint readers are too bulky, and therefore, the size of the portable storage device is still too large to achieve a slim and light design.

Further, the conventional fingerprint identification module mainly includes a substrate, a wafer, and a sealant. The wafer is disposed on the substrate and electrically connected to the substrate, and the encapsulant covers the surface of the substrate and a portion of the wafer for fixing the wafer and protecting the wires. In addition, the encapsulant needs to expose the sensing area of the wafer for finger fingerprint sensing.

However, when the finger touches the sensing area of the wafer, the wafer will withstand the force from the finger. Therefore, the wafer is liable to cause cracks in the wafer due to repeated stresses. In addition, the wafer is exposed to the air and is touched by the fingers. Dust particles in the external environment or oil or water marks on the fingers may cause distortion of the wafer.

Therefore, how to provide a fingerprint identification module to overcome the above-mentioned shortcomings has been However, it has become one of the important topics that the cause is to solve.

In view of the above problems, the present invention provides a portable storage device with fingerprint recognition function, which can set the fingerprint identification module on the storage device and achieve a slim design.

In order to achieve the above objective, the present invention provides a portable storage device having a fingerprint recognition function, including: a main substrate, a fingerprint identification module, a storage module, and a control module. The fingerprint recognition module is disposed on the main substrate. The storage module is disposed on the main substrate. The control module is disposed on the main substrate. The control module is electrically connected to the storage module and the fingerprint identification module to control the storage module and the fingerprint identification module.

The beneficial effect of the present invention is that the portable storage device with the fingerprint recognition function provided by the present embodiment can be fingerprint-identified by the fingerprint recognition module disposed on the portable storage device, so that it can be The correct user accesses the data, and by setting the miniaturized fingerprint recognition module in the portable storage device, the portable storage device is formed into a single body and can be simultaneously thin and light.

In addition, the dielectric constant of the mold layer 23, the color layer 243, and the protective layer 244 may be between 7 and 45. In other words, the height from the top of the protective layer 244 to the fingerprint recognition wafer 22 is very thin and the dielectric constant is high. Therefore, the mold layer 23, color The color layer 243 and the protective layer 244 do not affect the recognition function of the fingerprint recognition wafer 22.

It is worth mentioning that, since the fingerprint identification module 2 and the main substrate 1 share an encapsulation layer 24, that is, the fingerprint identification module 2 and the main substrate 1 have the same color protection layer, the fingerprint identification module 2 can be made. The thickness is thinner. Therefore, the signal connection end 214 or the pad 213 can be disposed on the second surface 212 of the substrate 21 by the added space, so as to be electrically connected to the control module 4, but the creation is not limited thereto. .
