Fig. 2 is the schematic cross-section of the Rigid Flex of one side shown in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope of protection of the invention.
In addition, the explanation of following embodiment is with reference to additional diagram, can in order to the specific embodiment implemented in order to illustrate the present invention.The direction term mentioned in the present invention, such as, " on ", D score, "front", "rear", "left", "right", " interior ", " outward ", " side " etc., it is only the direction with reference to annexed drawings, therefore, the direction term used be in order to better, be illustrated more clearly in and understand the present invention, instead of instruction or infer the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.
In describing the invention, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; It can be mechanical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition above-mentioned term concrete meaning in the present invention can be understood.
In addition, in describing the invention, except as otherwise noted, the implication of " multiple " is two or more.If there is the term of " operation " in this specification, it not only refers to independently operation, when cannot clearly distinguish with other operation, as long as the effect that can realize desired by this operation is then also included within this term.In addition, refer to by the number range that " ~ " represents the scope that the numerical value recorded before and after " ~ " is included as minimum value and maximum in this specification.In the accompanying drawings, structural similarity or identical representing with identical label.
Refer to Fig. 1, one side Rigid Flex of the present invention comprises dielectric layer 10 and wiring layer 20, described wiring layer 20 is laminated on described dielectric layer 10, described wiring layer 20 comprises many signal line 21 and many ground wires 22, the alternately configuration of described many signal line 21 and described many ground wires 22, the ground wire 22 that described in every bar, holding wire 21 correspondence is contiguous, ground wire 22 ground connection is to form signal circuit.
By interconnected ground wire 22 and holding wire 21, holding wire is the mode staggered each other, therefore can reduce interference each other between signal.Each signal line 21 is corresponding with a contiguous ground wire, can reduce the length of signal circuit.Via such wire laying mode, the position of holding wire of can making appropriate arrangements, and obtain good impedance matching.
By being arranged at many signal line ground wire one to one in the wiring layer of one side Rigid Flex in the present invention, by ground wire grounded thus can guarantee to form signal circuit in time in signal transduction process, impedance in circuit can not be increased, signal interference between many signal line also correspondingly can weaken, thus reach the technique effect of the transmission quality improving signal.
Further, described holding wire 21 is identical with the width of described ground wire 22.Signal is made to keep stable transfer in whole signal circuit.Meanwhile, the processing and manufacturing of one side Rigid Flex is also convenient to.
Further, described holding wire 21 and described ground wire 22 arranged in parallel.To ensure the coupling performance between corresponding holding wire 21 and ground wire 22, reduce the overall impedance value of signal circuit further.
Also comprise power line 23 and power ground 24 in the wiring layer 20 of the one side Rigid Flex of the embodiment of the present invention, described power line 23 is connected with power supply, for one side Rigid Flex provides electric current.Power line 23 forms discharge loop by power ground 24.Further, described many signal line 21 and described many ground wires 22 are only positioned at described power line 23 with on the side of described power ground 24.That is, described power line 23 and described power ground 24 are disposed adjacent, and described power line 23 and described power ground 24 are located on the side of described one side Rigid Flex.The object of setting like this is, can reduce the mutual interference between electric power loop and signal circuit, improves the transmission quality of signal.
Further, described power line 23 is equal with the width of described power ground 24 and be L, and described holding wire 21 is H with the width of described ground wire 22, then should meet 1/4L≤H≤1/3L.
Because power line 23 and power ground 24 are for providing electric current for whole one side Rigid Flex, the electric current therefore on it is greater than the electric current in each holding wire 21 and ground wire 22.Electric current in holding wire 21 and ground wire 22 is less, therefore can adopt less cross-sectional area.For holding wire 21 and ground wire 22 because the thickness of himself is very little, be therefore difficult to reduce its thickness again.Its cross-sectional area can be reduced by the width reducing holding wire 21 and ground wire 22 in the present embodiment.Thus reach the technique effect reducing one side Rigid Flex overall volume.Same width is too small also can cause holding wire 21 and ground wire 22 structural strength not, easily ruptures.The above-mentioned factor of comprehensive consideration, should ensure 1/4L≤H≤1/3L.
Further, in order to ensure the stability in power line 23 and power ground 24 transmission signal process, need to limit the current strength in signals layer.Power line 23 in the present embodiment and the ampacity of power ground 24 are 10 amperes per square millimeter (A/mm
2).
Incorporated by reference to Fig. 2; further; described wiring layer 20 is coated with insulating oil layer of ink 30; described insulating oil layer of ink 30 can comprise the anti-welding material of such as green paint; or can be the insulating material comprising pi (polyimide) or ABF film (ajinomotobuild-upfilm), it can protect the not oxidized or short circuit each other of the line construction of one side Rigid Flex inside.
For reducing the mutual interference of signal between wiring layer 20 and the external world further, provide the transmission quality of signal.One deck screen 40 can also be applied in described insulating oil layer of ink 30.Described screen 40 can be formed in the surface of this insulating oil layer of ink 30 in the mode of printing, wire mark by the electric conducting material such as copper slurry, silver slurry.Screen 40 can also adopt the conductive foil materials such as Copper Foil, silver foil, aluminium foil to be formed in the surface of this insulating oil layer of ink 30 in the mode of pressing or laminating.
