Description
Technical field
The utility model is related to circuit board technology field, more particularly to waterproof and dampproof circuit board.
Background technology
Flexible PCB is a kind of printed circuit board (PCB) being made using polyimides or polyester film as base material.Abbreviation soft board
Or FPC, have the advantages that high, lightweight Distribution density, thickness of thin, can free bend, folding, winding and thermal diffusivity it is good, extensively
Apply in MP3, MP4 player, computer, digital camera, mobile phone, medical treatment, automobile, space flight and military field.Because FPC is used
Copper clad laminate, so conduction property is splendid.But flexible PCB does not have water-proof function, when making moist or being stained with water, easily
Break down, or even can be short-circuited, damage other hardware.
Application Number (patent)：CN201520266161.5 discloses a kind of circuit board, including：Circuit board body, is bonded in
Splash guard in circuit board body, as in splash guard and for collecting the water receiving tank that water is conveniently focused on, sticks in water receiving
Drying agent chip on groove.The circuit board of this waterproof, blocks the water under spilling, protection circuit plate, and water is assembled, and concentrates suction in time
It is dry, not only avoid circuit board from breaking down, and avoid influence using the use of the product of circuit board, so as to prevent accident, prolong
Long life.
But the waterproof circuit is when in use, the local phenomenon made moist still occurs, so as to influence the electricity on circuit board
The use of sub- component, reduces its performance.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides the circuit board for carrying water-proof function, it is ensured that
It has preferable waterproof, dehumidifying and drainage performance, improves its service life.
The technical scheme that the utility model is used is：Waterproof and dampproof circuit board, including circuit substrate and panel, panel
Upper surface is equably disposed with above the upward some waterproof strips of ladder, waterproof strip from edge to centre direction and is equipped with anti-
Water film；Silica-gel desiccant is filled between some waterproof strips.
Further, a U-shaped guiding gutter has been also respectively connected with circuit substrate two cross sections parallel with waterproof strip,
U-shaped guiding gutter is made up of enhancing nylon plastic(s).
Further, each U-shaped guiding gutter uses glue sticking in the side of circuit substrate.
Further, the side of each U-shaped guiding gutter is additionally provided with osculum.
Further, each waterproof strip is semi-cylindrical structure, and the cross section of waterproof strip radius from panel
Successively decrease in center to marginal position direction.
Compared with prior art, the beneficial effects of the utility model are：Waterproof and dampproof circuit board of the present utility model,
Its panel upper surface is equably disposed with the upward some waterproof strips of ladder from edge to centre direction, by circuit board pad
Height, is equipped with membrane waterproofing above waterproof strip first in addition, plays waterproof and self-draining effect, when water droplet is in circuit
The optional position of membrane waterproofing, water under gravity, can be discharged into the side of circuit board along stepped inclined-plane automatically.
Finally, silica-gel desiccant is filled between some waterproof strips, can be will leak out in time upper to circuit board
Moisture absorption, and be dried, improve the wet-out property of circuit board.The waterproof and dehumidifying for finally improving circuit board are made
With.
Brief description of the drawings
Fig. 1 is the structural representation of one embodiment of waterproof and dampproof circuit board；
Wherein：1- circuit substrates, 2- panels, 3- waterproof strips, 4- membrane waterproofings, 5- silica-gel desiccants, the U-shaped guiding gutters of 6-,
7- osculums.
Embodiment
In order to deepen to understand of the present utility model, with reference to the accompanying drawings and examples to the utility model furtherly
Bright, the embodiment is only used for explaining the utility model, and protection domain of the present utility model is not constituted and limited.
As shown in figure 1, waterproof and dampproof circuit board, including circuit substrate 1 and panel 2, the upper surface of panel 2 is from edge to center
Position direction is equably disposed with the upward some waterproof strips 3 of ladder, and the top of waterproof strip 3 is equipped with membrane waterproofing 4；Some water proofs
Silica-gel desiccant 5 is filled between bar 3.
In the above-described embodiments, a U has been also respectively connected with it on two cross sections parallel with waterproof strip 3 of circuit substrate 1
Type guiding gutter 6, U-shaped guiding gutter 6 is made up of enhancing nylon plastic(s), and the guiding gutter has preferable durability.
Further, it is also possible to which each U-shaped guiding gutter 6 is manufactured more square using glue sticking in the side of circuit substrate 1
Just.
For more preferable draining, osculum 7 can also be additionally provided with the side of each U-shaped guiding gutter 6.
Or each waterproof strip 3 is designed as semi-cylindrical structure, and the cross section of waterproof strip 3 radius from panel
2 center to marginal position direction is successively decreased, and plays more preferable drainage effect.
What embodiment of the present utility model was announced is preferred embodiment, but is not limited thereto, the common skill of this area
Art personnel, easily according to above-described embodiment, understand spirit of the present utility model, and make different amplifications and change, but as long as
