Fingerprint recognition module is widely used to the electronic product industry such as mobile phone, notebook computer at present.Conventional fingerprint mould
Group encapsulating structure includes：Becket, protective layer, fingerprint recognition chip and circuit board.Protective layer is covered in fingerprint chip surface；Refer to
Line chip is connected by conductive material with circuit board, and point is filled with filling glue to seal between chip periphery and circuit board, is typically designed
Scheme chip is smaller than circuit board, and glue spots are on circuit boards；Becket is connected by glue with circuit board.
Mobile phone industry is high-accuracy industry, and fingerprint module will turn into smart mobile phone standard configuration, still, sometimes by complete machine end
Size influences, and chip than circuit board size bigger can avoid Assembly Interference.However, when chip is bigger than circuit board size, no dispensing
Position, so as to cause module reliability can not be by the way that product function can not ensure.
Utility model content
A purpose of the present utility model is to propose that one kind can solve the problems, such as that chip can not dispensing when bigger than circuit board
Point plastic structure；
Another purpose of the present utility model is to propose a kind of intelligent terminal for including above-mentioned plastic structure.
For up to this purpose, on the one hand, the utility model uses following technical scheme：
One kind point plastic structure, including connecting sheet circuit board and chip, the connecting sheet circuit board include body in flakes and are arranged at
Multiple units in flakes on body in flakes, the end set of each unit in flakes have dowel, and the chip is set
In on the dowel, the edge of the chip is located in the edge of the dowel, point between the chip and the dowel
It is filled with filling glue.
Further, copper sheet is laid on the connecting sheet circuit board, filling glue is filled between chip and the copper sheet.
Further, welded between the chip and the dowel by soldering.
Further, the chip is rounded, oval, rectangle or rhombus.
Further, when the chip is rectangular or during rhombus, the vertex rounding of the chip.
Further, the chip sets matcoveredn back to the side of the circuit board.
Further, the chip is fingerprint recognition chip.
Further, the connecting sheet circuit board is flexible PCB.
On the other hand, the utility model uses following technical scheme：
A kind of intelligent terminal, including the point plastic structure described in any of the above-described.
Further, the intelligent terminal is mobile phone or computer.
The beneficial effects of the utility model are as follows：
Provided by the utility model plastic structure and intelligent terminal, be structure in flakes during connecting sheet circuit board supplied materials, by
The end set size of the unit dowel bigger than chip size in flakes, can solve chip and be led greatly than circuit board end size
What is caused can not dispensing problem.The functional reliability of fingerprint module has been effectively ensured.
Brief description of the drawings
Fig. 1 is the structural representation for the point plastic structure that the utility model preferred embodiment one provides.
In figure：
1st, body in flakes；2nd, unit in flakes；3rd, chip；4th, dowel.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Preferred embodiment one：
This preferred embodiment provides a kind of point plastic structure, including connecting sheet circuit board and chip 3, connecting sheet circuit board include connecting
Piece body 1 and it is arranged at multiple unit 2 in flakes in flakes on body 1, at least partly the end set of unit 2 has dowel in flakes
4, chip 3 is arranged on dowel 4, and the edge of chip 3 is located in the edge of dowel 4, and point is filled between chip 3 and dowel 4
Fill glue.In the present embodiment, chip 3 is preferably fingerprint recognition chip 3, and connecting sheet circuit board is flexible PCB.Multiple fingers are at least
Two, multiple units in flakes 2 are preferably parallel set.
During connecting sheet circuit board supplied materials it is structure in flakes in the present embodiment, passes through the end set size ratio in unit 2 in flakes
The big dowel 4 of the size of chip 3, can solve the problems, such as that chip 3 can not dispensing caused by bigger than circuit board size.Point is cementing
Connecting sheet circuit board is cut after beam, obtains required product, you can ensures that the size of chip is more than the size of circuit board and kept away
Exempt to produce Assembly Interference, and the correlation function reliability of chip can be ensured.
In the present embodiment, preferably, copper sheet is laid on connecting sheet circuit board, filling glue is filled in chip 3 and copper sheet
Between, set copper sheet to avoid Electro-static Driven Comb (Electro-Static discharge, ESD) risk in a plastic structure.
In the present embodiment, welded between chip 3 and dowel 4 preferably by soldering.In the present embodiment, the shape of chip 3
Shape is not specifically limited, and can be configured according to specific needs, for example, chip 3 preferably but be not limited to it is rounded, oval,
Rectangle or rhombus.Rectangle can be rectangle or square.
In the present embodiment, in order to improve the comfortableness used, when chip 3 is rectangular or during rhombus, the vertex of chip 3 is fallen
Fillet.
In the present embodiment, chip 3 sets matcoveredn back to the side of circuit board, to avoid chip 3 from being damaged.Protection
