Description
Technical field
The utility model is related to electronic circuit board to be related to field, particularly relates to a kind of based on the quiet of PCB
Electric safeguard structure.
Background technology
Electrostatic is a kind of natural phenomena of objective reality, and the mode of generation is various, such as contact, friction, appliance chamber sensing.
The characteristics of the characteristics of electrostatic is accumulation for a long time, high voltage, low battery, low current and short action time, electrostatic is to our electronics
The component of equipment has irreversible infringement.
Electro-static Driven Comb electronic component, is a kind of electronic component for electrostatic quick release, and this device is to system
Electronic component there is good protective action.But if the quantity for increasing Electro-static Driven Comb electronic component is carried out to system
Protection, certainly will increase certain cost.Nowadays how product cost is reduced in electron trade, as the life that enterprise increasingly payes attention to
Cun Zhi roads.
Drawbacks described above, is worth improving.
The content of the invention
In order to overcome the shortcomings of existing technology, the utility model provides a kind of electrostatic protection knot based on PCB
Structure.
Technical solutions of the utility model are as described below：
A kind of electrostatic protection structure based on PCB, including PCB main body, in the PCB main body
It is provided with holding wire and ground wire, it is characterised in that in the PCB main body, is provided with some letters relative one by one
Number tip and ground connection tip, the sophisticated and described ground connection of the signal is sophisticated to connect the holding wire and the ground wire respectively, and
The signal is sophisticated and ground connection tip parcel is provided with welding resistance windowing.
Further, the sophisticated and described ground connection tip of the signal is equal in magnitude.
Further, the sophisticated and described ground connection tip of the signal is conductive copper sheet.
Further, the sophisticated and described ground connection tip of the signal is zigzag tip, and the sophisticated saw of the signal
The zigzag tip at the sophisticated and described ground connection tip of dentation is relative one by one.
Further, the spacing between the sophisticated and described ground connection tip of the signal is at least 4mil.
Further, the edge width of the welding resistance windowing is at least 3mil.
According to the utility model of such scheme, its advantage is that the utility model uses electronic circuit board copper sheet
Special shape corrosion technology, extra electronic component is not increased, you can reach the purpose of quick release electrostatic, saving makes
With the cost of ESD components, production cost is reduce further, while the zigzag tip for using can further disperse electrostatic
Release, reduces Electro-static Driven Comb risk, simple structure, beneficial to the manufacturing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, signal tip；2nd, it is grounded tip；3rd, welding resistance windowing.
Specific embodiment
Below in conjunction with the accompanying drawings and implementation method is conducted further description to the utility model：
As shown in figure 1, a kind of electrostatic protection structure based on PCB, including PCB main body, the PCB electricity
Holding wire and ground wire are provided with the plate main body of road, some letters relative one by one are additionally provided with the PCB main body
Number tip 1 and ground connection tip 2, signal tip 1 and ground connection tip 2 connect holding wire and ground wire respectively（Not shown in figure）, and
Signal tip 1 and ground connection tip 2 surround and are provided with welding resistance windowing 3.
Signal tip 1 is identical with the size at ground connection tip 2, and is conductive copper sheet, in the present embodiment, signal tip 1
Zigzag tip, and the zigzag tip at signal tip 1 and the zigzag tip size for being grounded tip 2 are with tip 2 is grounded
It is equal, relative one by one.Jagged tip, can further disperse Electro-static Driven Comb, reduce Electro-static Driven Comb risk.
In the present embodiment, the spacing between signal tip 1 and ground connection tip 2 is at least 4mil, to ensure to process spacing,
The edge width of welding resistance windowing 3 is at least 3mil, to ensure green oil bridge spacing.
The utility model utilizes point discharge principle, and the tip and connection that connection holding wire is set in PCB connect
The ground connection tip of ground wire, electric charge is especially intensive at the tip at signal tip, and the electric field in its neighbouring air is especially strong so that its
Ion in neighbouring air is accelerated, and the ionic bombardment air molecule of these high-speed motions makes more molecular ionizations, at this moment
Air turns into conductor, the such electrostatic ground connection for being passed to opposite tip quickly, and then is delivered to ground wire, and such electrostatic is just
Ground level is released to quickly to get on, and electrostatic protection has been carried out to whole system.
The utility model does not increase extra electronics unit device using the special shape corrosion technology of electronic circuit board copper sheet
Part, you can reach the purpose of quick release electrostatic, saves using the cost of ESD components, reduce further production cost,
The zigzag tip for using simultaneously can further disperse Electro-static Driven Comb, reduce Electro-static Driven Comb risk, simple structure, beneficial to production
Manufacture.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of the utility model appended claims.
Exemplary description is carried out to the utility model patent above in conjunction with accompanying drawing, it is clear that the reality of the utility model patent
Now it is not subject to the restrictions described above, as long as the method design for employing the utility model patent is various with what technical scheme was carried out
Improve, or it is not improved the design of the utility model patent and technical scheme are directly applied into other occasions, in this reality
With in new protection domain.
