Abstract
The utility model belongs to the technical field of PCB manufacture, especially relates to a PCB plate with cross blind holes. The blind holes are respectively formed on at least two layers of circuit boards in the staggered way, one part of the least two blind holes is formed on the same circuit board, the circuit board is provided with two conduction circuits for conducting blind hole circuits, thus the circuits on different circuit boards of the PCB plate are electrically connected and conducted, simultaneously the positions of the blind holes can be flexibly adjusted according to the design requirement, thus the arrangement of the circuits on the circuit boards is greatly facilitated, and the phenomenon that the circuit is adjusted and the layer number of the circuit boards is increased due to setting the blind holes, is avoided.
Description
Technical field
The utility model relates to PCB and makes the field, relates in particular to a kind of pcb board spare with the intersection blind hole.
Background technology
Flourish along with electronic industry, electronic product trends towards complicated, the volume microminiaturization of function gradually, namely in the entity space of existence, makes electronic product possess more function as much as possible, and volume is littler simultaneously.Pcb board spare (PrintedCiruitBoard as one of electronic product core component, printed circuit board (PCB)), for tackling the complicated and volume microminiaturization needs to function of above-mentioned electronic product, circuit is arranged and is become increasingly complex on the pcb board spare, and adopts the wiring board that has multilayer as a rule.
Under some special designing requirement, circuit is electrically connected conducting on the different wiring boards with being positioned on the pcb board spare, and normally adopting in present technology to need two wiring boards of mutual conduction to offer through hole or the blind hole that runs through the two described wiring boards that need mutual conduction.If also be provided with the All other routes plate between the two described wiring boards, then through hole or blind hole together can be passed the All other routes plate.But in the wiring board design of reality, because whole wiring board must be through hole or the remaining certain space of blind hole, usually will carry out line transfer handles, in some cases, also must increase the number of plies of wiring board, and in the design of conventional pcb board spare, usually the thickness of pcb board spare is that clear and definite requirement is arranged, and the number of plies that increases wiring board can cause making thickness designing requirement more than expected behind the pcb board spare.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, provides a kind of with intersecting the pcb board spare of blind hole, realizes being positioned at that circuit on the different wiring boards is electrically connected conducting and the circuit that do not influence each wiring board is arranged.
The utility model is achieved in that a kind of pcb board spare with the intersection blind hole, comprises the wiring board of two-layer or two-layer above mutual superposition, and misplacing respectively on the two-layer at least described wiring board offers a plurality of blind holes; Have at least the part of two described blind holes to be opened in on the described wiring board of one deck, and this layer wiring board is provided with two conducting circuits that make described blind hole circuit turn-on.
Particularly, the sidewall of each described blind hole is provided with heavy copper layer.
Particularly, this pcb board spare also comprises six layers of described wiring board, and described blind hole comprises that the upper surface by pcb board spare passes first blind hole of four layers of wiring board of ground floor wiring board to the and second blind hole of passing four layers of wiring board of layer 6 wiring board to the successively by the lower surface of pcb board spare successively.
Particularly, described first blind hole penetrates described the 4th layer of wiring board, and described second blind hole is worn to the inside of described the 4th layer of wiring board.
Compared with prior art, the utlity model has following technique effect: the utility model offers blind hole by misplacing respectively on two-layer at least described wiring board, and a part that has two described blind holes at least is opened in on the described wiring board of one deck, and this layer wiring board is provided with the conducting circuit that makes two described blind hole circuit turn-ons, so realized being positioned on the pcb board spare circuit electrical connection conducting on the different wiring boards, simultaneously owing to the position of described blind hole setting can be adjusted flexibly according to the design needs, thereby make things convenient for the layout of circuit on each described wiring board greatly, avoided that the wiring board of levels needs line transfer to handle and even increase the problem of the number of plies of wiring board when blind hole is set.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Present embodiment is example with the pcb board spare that comprises six layers of wiring board, so that characteristics of the present utility model to be described.Certainly, enforcement of the present utility model is not subjected to the restriction of the wiring board number of plies.
A kind of pcb board spare with the intersection blind hole, the wiring board that comprises six layers of mutual superposition, for convenience of description with above-mentioned six layers of wiring board to top to bottm being designated as ground floor wiring board 11, second layer wiring board 12, the 3rd layer of wiring board 13, the 4th layer of wiring board 14, layer 5 wiring board 15 and layer 6 wiring board 16 successively, to realize the conducting that is electrically connected of described ground floor wiring board 11 and described layer 6 wiring board 16 in the present embodiment.Described ground floor wiring board 11 by the upper surface of pcb board spare offers first blind hole 21 between described the 4th layer of wiring board 14, described first blind hole 21 penetrates described the 4th layer of wiring board 14 and replaces described layer 5 wiring board 15; Described layer 6 wiring board 16 by the lower surface of pcb board spare offers second blind hole 22 between described the 4th layer of wiring board 14, described second blind hole 22 penetrates described the 4th layer of wiring board 14, and does not penetrate described the 3rd layer of wiring board 13.Wherein, shift to install between described first blind hole 21 and described second blind hole 22, and described first blind hole 21 can freely be adjusted according to the needs that circuit on each described wiring board is arranged with the relative position of described second blind hole 22, and it is not arranged circuit on each described wiring board and causes bad influence.
For realizing the conducting that is electrically connected of described first blind hole 21 and described second blind hole 22, be provided with the conducting circuit (not drawing among the figure) of described first blind hole 21 of circuit turn-on and second blind hole 22 at the lower surface of described the 4th layer of wiring board 14.So far, can be by drawing conductive materials from described first blind hole 21 and second blind hole 22, just can realize the conducting that is electrically connected of described ground floor wiring board 11 and described layer 6 wiring board 16.
