[0002] Capacitive fingerprint module: Its principle is similar. On a "flat plate" integrated with thousands of semiconductor devices, the finger is placed on it and forms the other side of the capacitor (inductor). Since the finger plane is uneven, the actual distance between the convex and concave points in contact with the flat plate is different, and the capacitance / inductance values ​​formed are also different. Based on this principle, the device summarizes the different values ​​collected, thus completing the fingerprint collection.

[0003] Existing fingerprint modules require glue dispensing during production. This process usually involves attaching a single IC module to a PCB board, and then sealing the IC and PCB board with glue. This single processing method is inefficient and affects production speed. Utility Model Content
