Position construction and operation, therefore be not considered as limiting the invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, and can also be detachably connected, or integrally connect for example, it may be being fixedly connected
It connects；It can be mechanical connection；It can be directly connected, can also can be indirectly connected through an intermediary in two elements
The connection in portion.For the ordinary skill in the art, the tool of above-mentioned term in the present invention can be understood with concrete condition
Body meaning.
In addition, in the description of the present invention, unless otherwise indicated, the meaning of " plurality " is two or more.If this
The term for occurring " process " in specification, refers not only to independent process, when can not clearly be distinguished with other process, as long as
It can realize that the effect desired by the process is then also included in this term.In addition, the numerical value model indicated with "~" in this specification
It refers to the range that "~" front and back numerical value recorded is included as minimum value and maximum value to enclose.In the accompanying drawings, structure
Similar or identical is indicated by the same numeral.
Referring to Fig. 1, the single side Rigid Flex of the present invention includes dielectric layer 10 and wiring layer 20,20 layers of the wiring layer
It is laminated on the dielectric layer 10, the wiring layer 20 includes a plurality of signal wire 21 and a plurality of ground wire 22, a plurality of signal wire
21 and a plurality of ground wire 22 be alternately arranged, every signal wire 21 corresponds to a neighbouring ground wire 22, the ground connection of ground wire 22 with
Form signal circuit.
By interconnected ground wire 22 and signal wire 21, signal wire is the mode being staggered each other, therefore can reduce signal
Between mutual interference.Each signal line 21 is corresponding with a neighbouring ground wire, can reduce the length of signal circuit.Via
Such wire laying mode, the position for the signal wire that can make appropriate arrangements, and obtain good impedance matching.
By being set to the one-to-one ground wire of a plurality of signal wire in the wiring layer of single side Rigid Flex in the present invention,
By ground wire grounded so as to ensuring to form signal circuit in signal transduction process in time so that the impedance in circuit will not increase
Greatly, the signal interference between a plurality of signal wire also can accordingly weaken, to reach the technique effect for the transmission quality for improving signal.
Further, the signal wire 21 and the ground wire 22 is of same size.So that signal is in entire signal circuit
It keeps stablizing transmission.Meanwhile also allowing for the processing and manufacturing of single side Rigid Flex.
Further, the signal wire 21 and the ground wire 22 are arranged in parallel.To ensure corresponding signal wire
Coupling performance between 21 and ground wire 22 further decreases the overall impedance value of signal circuit.
Further include power cord 23 and power ground 24, institute in the wiring layer 20 of the single side Rigid Flex of the embodiment of the present invention
It states power cord 23 with power supply to be connected, electric current is provided for single side Rigid Flex.Power cord 23 is put by the formation of power ground 24
Electrical circuit.Further, a plurality of signal wire 21 and a plurality of ground wire 22 are only located at the power cord 23 and the power supply
On the side of ground wire 24.That is, the power cord 23 and the power ground 24 are disposed adjacent, and 23 He of the power cord
The power ground 24 is located on the side of the single side Rigid Flex.The purpose of such setting is, can reduce electricity
Interfering with each other between resource loop and signal circuit improves the transmission quality of signal.
Further, the power cord 23 is equal with the width of the power ground 24 and is L, the signal wire 21 with
The width of the ground wire 22 is H, then should meet 1/4L≤H≤1/3L.
Since power cord 23 and power ground 24 are used to provide electric current for entire single side Rigid Flex, electricity thereon
Stream is more than the electric current in each signal wire 21 and ground wire 22.Electric current in signal wire 21 and ground wire 22 is smaller, thus may be used compared with
Small cross-sectional area.It is difficult to reduce its thickness again for signal wire 21 and ground wire 22 due to the thickness of its own very little
Degree.It can reduce its cross-sectional area by reducing the width of signal wire 21 and ground wire 22 in the present embodiment.It is reduced to reach
The technique effect of single side Rigid Flex overall volume.Equally width is too small will also result in 22 structural strength of signal wire 21 and ground wire
Not enough, it is easily broken off.Comprehensive consideration above-mentioned factor should ensure that 1/4L≤H≤1/3L.
Further, it in order to ensure the stability in 24 transmission signal process of power cord 23 and power ground, needs to letter
Current strength in number floor is defined.The current-carrying capacity of power cord 23 and power ground 24 in the present embodiment, which is 10 amperes, often puts down
Square millimeter (A/mm2)。
Incorporated by reference to Fig. 2, further, insulating oil layer of ink 30, the insulating oil layer of ink 30 are coated on the wiring layer 20
It may include the anti-welding material of for example green paint, or it includes polyimide (polyimide) or ABF films (ajinomoto that can be
Build-up film) insulating materials, the line construction inside single side Rigid Flex can be protected not oxidized or short each other
Road.
To further decrease interfering with each other for signal between wiring layer 20 and the external world, the transmission quality of signal is provided.May be used also
To coat one layer of shielded layer 40 in the insulating oil layer of ink 30.The shielded layer 40 can with the conductive materials such as copper slurry, silver paste with
It prints, the mode of wire mark is formed in the surface of the insulating oil layer of ink 30.Shielded layer 40 can also use copper foil, silver foil, aluminium foil etc.
Conductive foil material is formed in the surface of the insulating oil layer of ink 30 in a manner of pressing or be bonded.
