Embodiment
Below in conjunction with the accompanying drawings and the principle and structure of the utility model is described in detail in embodiment.
As shown in Figure 2, Figure 3, Figure 4, the utility model proposes a kind of fingerprint recognition module, including chip body 1, chip body
1 is in tabular, and chip body is fingerprint recognition chip, and the front of chip body 1 is coated with ink layer 11, and ink layer 11 can be dumb light
Type ink or light type ink, as protective layer, increase exterior texture and beauty.Pin is interval with the back side of chip body 1
Foot 12, the back side of 12 vertical chip body 1 of stitch, the circuit for chip body 1 connect, and stitch 12 is arranged in what chip body was square
Ring-type, the raised ring Xing Loutong areas 13 of 1 dorsal edge of chip body in the outside of stitch 12, for being grounded.On the inside of stitch
The chip body back side is additionally provided with one piece of square Lou Tong area 14, and the surface indentation in square Lou Tong areas 14, makes it not exist with 1 back side of chip body
Same plane, and conductive fabric is posted on square 14 surface of Lou Tong areas, there be a corner unfilled corner in square Lou Tong areas 14, and separation forms one piece
Single corner block 141, for installing when, distinguish the prime direction of chip body stitch and play foolproof function.
In the utility model, the big I of chip body 1 needs to formulate according to different, and stitch 12 and nearest chip body 1
The distance at edge is greater than or equal to 0.8mm, and the thickness of ink layer 11 is between 0.020mm to 0.045mm.
As shown in Figure 5, Figure 6, another embodiment of the utility model proposes a kind of for installing above-mentioned fingerprint recognition module
PCB main board 2, the attachment face of PCB main board 2 is equipped with the through hole 21 of corresponding chip body stitch 12, through hole 21 be nearby additionally provided with
The mainboard Lou Tong areas 22 that chip body annular Lou Tong areas and square Lou Tong areas profile are correspondingly arranged, make chip body 1 pacify with PCB main board 2
Normal circuit connects during dress, instead of FPC soft boards, other peripheral components on PCB main board 2 is had more installation spaces.PCB master
The edge that chip body 1 is corresponded on plate 2 is also coated with white silk-screen, and contraposition during for installing, reduces installation difficulty.After installation,
Coated with filling glue at the outer rim that chip body 1 is bonded with PCB main board 2, prevent chip body 1 with PCB main board 2 because mismachining tolerance occurs
