Description
【Technical field】
The utility model is related to printed circuit board field, and in particular to a kind of Wiring structure of optimization coiling signal quality.
【Background technology】
Printed circuit board（Printed Circuit Board, pcb board）Also known as printed circuit board (PCB), printed substrate, are electricity
The important component of physical support and the signal transmission of sub- product.Cabling in pcb board plays the different chip pins of connection
Effect.Especially in some parallel signal transmission environments, because many root signals are transmitted together, it is necessary to ensure to transmit signal
Between it is isometric, because the position sent and received of every signal is different, air line distance has with short, therefore, apart from short
Cabling just must by itself extra coiling come with the cabling of other distances keep it is isometric.
Our traditional ways are exactly that coiling is directly carried out after cabling designs line width, do not do more to winding portion
Processing, actually using the cabling of winding mode, due to the biography between winding portion signal segment and section equivalent to progress differential mode
It is defeated, therefore can be significantly decreased in the impedance of the part, so that the impedance of overall cabling changes, influence signal matter
Amount.How to ensure that relatively good signal quality is worth research in the case of coiling.
【Utility model content】
In order to overcome the shortcomings of existing technology, the utility model provides a kind of cabling for optimizing coiling signal quality
Structure.
Technical solutions of the utility model are as described below：A kind of Wiring structure for optimizing coiling signal quality, including signal are walked
Line, the signal lead is distributed on pcb board, it is characterised in that the signal lead include be sequentially connected first straight line section,
Around line segment and second straight line section, described uniformly bent around line segment is mutually put down between cabling, and the flat part on line segment
OK, the first straight line section is equal with the line width of second straight line section, and the line width around line segment is first straight line section
Line width 85%-95%.
According to the utility model of said structure, it is characterised in that the line width around line segment is first straight line section
Line width 90%.
According to the utility model of said structure, it is characterised in that the bending section on line segment is bent with curved line.
According to the utility model of said structure, its advantage is, by the line width phase of the winding portion of signal lead
Line width for straight line portion reduces, so as to increase the impedance of winding portion, to cause winding portion and straight line as far as possible
Partial impedance is consistent, so as to ensure the uniformity of the impedance of signal lead, and then optimizes or improve the quality of signal transmission.
【Brief description of the drawings】
Fig. 1 is structural representation of the present utility model.
In figure, 1, pcb board；2nd, first straight line section；3rd, around line segment；4th, second straight line section；5th, kink；6th, flat part.
【Embodiment】
Below in conjunction with the accompanying drawings and the utility model is further described embodiment：
As shown in figure 1, a kind of Wiring structure for optimizing coiling signal quality, including signal lead, signal lead is distributed in
On pcb board 1, and signal lead include be sequentially connected first straight line section 2, around line segment 3 and second straight line section 4, it is equal around line segment 3
Even bending cabling, the bending section 5 on line segment 3 is bent with curved line, and is parallel to each other between the flat part 6 on line segment 3, the
One straightway 2 is equal with the line width of second straight line section 4, and is the 90% of the line width of first straight line section 2 around the line width of line segment 3.
In the present embodiment, around line segment 3 line width for first straight line section 2 line width 90%, will script cabling width drop
Low by 10%, on this condition, the impedance of winding portion and the impedance of straight line portion are basically identical, and guarantee signal that can be maximum is transmitted
Quality.
When signal is transmitted, because straight line portion cabling is not disturbed by itself, therefore impedance can be according to original
The line width values of setting enter walking line；But when coiling is carried out, because the direction of routing of adjacent winding portion is opposite（On one
Once, or a first from left is right）, and the spacing of winding portion is typically only 2 times of line width, therefore the part can be regarded as poor
Divide transmission mode, if like this entering walking line also according to original line width, the impedance of winding portion will compare straight line portion
Impedance it is low.In order to keep the uniformity of impedance, the utility model improves this by controlling to reduce the line width of winding portion
Partial impedance, and the line width of winding portion is consistent.
Line width of the utility model by the line width of the winding portion of signal lead relative to straight line portion is reduced, so that
Increase the impedance of winding portion, as to cause the impedance of winding portion and straight line portion consistent as possible, so as to ensure that signal is walked
The uniformity of the impedance of line, and then optimize or improve the quality of signal transmission.
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 for employing the utility model patent conceives various with technical scheme progress
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.
