Abstract
The utility model discloses a kind of pcb board structure by back drill with realizing cracking down illegal activities under optical fiber interface via in pcb board technical field, including pcb board and through the non-ground via of the pcb board, non- ground via is connected with the internal layer signal wire of pcb board internal layer, the side of non-ground via is provided with optical fiber interface, and the non-ground via close to optical fiber interface side is provided with back drill region.The utility model efficiently solve the problems, such as optical fiber interface part again on PCB placement-and-routing utilization rate.
Description
Technical field
The utility model is related to circuit board technology field, specifically, is to be related to one kind to realize optical fiber interface by back drill
Lower cracking down illegal activities via pcb board structure.
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.Conventional fiber interface is typically all crimped in pcb board, light
Fine interface is all metal shell, so being with not allowing cracking down illegal activities via below optical fiber interface, is otherwise easily caused optical fiber interface
With the situation of non-ground via short circuit.
But with constantly developing rapidly for information age, pcb board tends to highly dense high integration development, and such structure is held
The waste of pcb board layout is easily caused, veneer utilization rate how is improved just into a current major issue.
The content of the invention
In order to overcome the shortcomings of existing technology, the utility model provides one kind and realizes cracking down illegal activities under optical fiber interface by back drill
The pcb board structure of ground via, efficiently solve the problems, such as optical fiber interface part again on PCB placement-and-routing utilization rate.
Technical solutions of the utility model are as described below：
Pass through the pcb board structure of back drill with realizing cracking down illegal activities under optical fiber interface via, it is characterised in that including pcb board and pass through
The non-ground via of the pcb board is worn, the non-ground via is connected with the internal layer signal wire of the pcb board internal layer, the non-ground mistake
The side in hole is provided with optical fiber interface, and the non-ground via close to the optical fiber interface side is provided with back drill region.
According to the utility model of such scheme, it is characterised in that back drill region face where the optical fiber interface
Layer is extended at the internal layer signal wire.
According to the utility model of such scheme, its advantage is, the utility model cracking down illegal activities under optical fiber interface
Via, solve the problems, such as optical fiber interface part again on PCB placement-and-routing utilization rate, effectively increase PCB single board utilization rate,
So as to reduce the pressure of placement-and-routing spatially.

Embodiment
Below in conjunction with the accompanying drawings and the utility model is further described embodiment：
As shown in figure 1, a kind of pcb board structure by back drill with realizing cracking down illegal activities under optical fiber interface via, including pcb board 10
With the non-ground via 30 through pcb board 10, non-ground via 30 is connected with the internal layer signal wire 40 of the internal layer of pcb board 10, non-ground via
30 side is provided with optical fiber interface 20, and the non-ground via 30 close to the side of optical fiber interface 20 is provided with back drill region 50.
It is preferred that, back drill region 50 is extended at internal layer signal wire 40 from the place surface layer of optical fiber interface 20.
In the present embodiment, optical fiber interface 20 is directed to crimp the interface of metal shell, and optical fiber interface 20 is arranged at PCB
On the top surface 11 of plate 10, the circuit of bottom surface 20 is connected to internal layer signal wire 40 by the non-ground via after back drill, from top surface 11 to
The non-ground via area of internal layer signal wire 40 is stub, and this part is connect by back drilling method formation back drill region 50, now optical fiber
Non- ground via under mouth 20 would not be with the short circuit of optical fiber interface 20 on top surface 11.
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.
