Abstract
A smart card fingerprint identification module packaging structure includes a first insulating layer, an insulating protective layer, a shielding layer, a second insulating layer, a fingerprint sensing area and bump pads. A first patterned circuit layer is embedded in the first insulating layer, and part of this layer serves as a first sensing circuit. A second patterned circuit layer is disposed on the second surface of the first insulating layer, and part of this layer serves as a second sensing circuit. A patterned metal layer is disposed on the second insulating layer and covers the outer surface of the second insulating layer as a shielding layer. The shielding layer corresponding to the first and the second sensing circuits is hollowed out to serve as a fingerprint sensing area. The longitudinal projections of the first sensing circuit and the second sensing circuit are staggered from each other without overlapping.
