Description
Technical field
This practicality is related to electronic device field, more particularly to a kind of new waterproof circuit board.
Background technology
Flexible PCB is using polyimides or polyester film as a kind of printed circuit board (PCB) made of base material.Abbreviation soft board
Or FPC, have the advantages that Distribution density is high, light-weight, thickness is 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 adopted
With copper clad laminate, so conduction property is splendid.But existing flexible PCB does not have water-proof function, making moist or be stained with water
When, easily break down, or even short circuit can occur, damage other hardware；The prior art does not solve the problem of so also.
In addition for electronic equipment, when work, can all produce certain heat, so that equipment internal temperature is rapid
Rise, if not in time distributed the heat, heating that equipment will continue, device will fail because of overheat, electronics
The unfailing performance of equipment will decline.Therefore, carry out good radiating treatment to circuit board to be very important, due to circuit board
Volume it is less and less, and electronic device of its carrying is more and more, and therefore, the heat dissipation of circuit board, which becomes, to be influenced circuit board and stablize
The outstanding problem of property.The especially circuit board of illuminating product, its caloric value higher.Existing heat dissipation for circuit board means include passing through
Heat dissipation is realized in rational cabling design, or using means such as radiator, heat-conducting plates, but cost is higher.
Utility model content
In order to solve above-mentioned technical problem, the utility model provides a kind of new waterproof circuit board, specifically
Technical solution is:
A kind of new waterproof circuit board, including circuit board body and splash guard, the splash guard are placed in the circuit board sheet
Body top, the splash guard is interior to be equipped with water receiving tank, and the water receiving tank is adhesive with drying agent chip, and the area of the splash guard is more than upper
The area of circuit board is stated, being cohered between the circuit board body and splash guard has adhesive layer, and the circuit board body includes bottom
Plate, electronic device, separation layer, thermal hole and heat dissipating layer, the separation layer are arranged on above bottom plate, and separation layer includes multilayer insulation
Layer, insulating layer is sequentially overlapped, and the thermal hole is longitudinally disposed in the isolation layer and to run through separation layer, the heat dissipating layer be arranged on every
On absciss layer, the electronic device is arranged on heat dissipating layer, and the electronic device is located at the top of thermal hole, and the thermal hole runs through
The heat dissipating layer is contacted with electronic device.
The thickness of the separation layer is less than 110 μm, and splash guard is soft plastic plate, and the drying agent chip is silica dehydrator
Agent.
Acquired technique effect is the utility model compared with prior art:The utility model is novel in design, manufacture and
Easy to use, cost is relatively low, and the utility model provides a kind of circuit board of waterproof, blocks the water under spilling, protection circuit plates, and
Water is assembled, and concentrates blot in time, not only avoids circuit board from breaking down, but also avoids influencing the product using circuit board
Use, so as to prevent accident, prolong the service life.
In addition the heat that the circuit board of the utility model can be produced electronic device by thermal hole and bottom plate body is fast
Speed distributes, so as to avoid electronic device peripheral temperature excessive, causes fluctuation of service；In addition, its structure is simpler, it is easy to
Manufacture, so as to reduce manufacture cost.
Brief description of the drawings

1 top of circuit board body, the splash guard 2 is interior to be equipped with water receiving tank 3, and the water receiving tank 3 is adhesive with drying agent chip 4, described
The area of splash guard 2 is more than the area of foregoing circuit plate 1, and being cohered between the circuit board body 1 and splash guard 2 has adhesive layer
5, the circuit board body 1 includes bottom plate 6, electronic device 7, separation layer 8, thermal hole 9 and heat dissipating layer 10, and the separation layer 8 is set
Put above bottom plate 6, separation layer 8 includes multilayer dielectric layer 81, and insulating layer 81 is sequentially overlapped, and the thermal hole 9 is disposed longitudinally on
In separation layer 8 and run through separation layer 8, the heat dissipating layer 10 is arranged on separation layer 8, and the electronic device 7 is arranged on heat dissipating layer
On 10, the electronic device 7 is located at the top of thermal hole 9, and the thermal hole 9 connects through the heat dissipating layer 10 with electronic device 7
Touch.
The thickness of the separation layer 8 is less than 110 μm, and splash guard 2 is soft plastic plate, and the drying agent chip 4 is done for silica gel
Drying prescription.
Binding agent is uniformly coated with circuit boards, and splash guard is placed on binding agent and is suppressed, then by drying agent chip, nothing
It is that the transformation of in the market circuit board, simple process and low cost can be achieved to need excessive step.
