Hole, although being able to satisfy the demand of test, under efficiency is very low when the pcb board number of plies is more.
Utility model content
To solve the above problems, the purpose of this utility model is to provide a kind of pcb boards with probe aperture, in pcb board
One radium-shine hole is set as probe aperture, is detected simultaneously for multi-layer PCB and establishes hardware foundation.
The technical solution adopted by the utility model to solve the problem is as follows:
In a first aspect, the utility model proposes a kind of pcb boards with probe aperture, comprising: substrate and be pressed on substrate
The layers of copper on surface；It further include the resin plate of pressing with the layers of copper upper surface；
It further include detection cavity and exploration hole, in resin plate, the exploration hole is connected the detection cavity with detection cavity,
The exploration hole runs through layers of copper and substrate.
Further, between the upper surface of the layers of copper and the lower surface of detection cavity further include radium for removing cull
Penetrate lead.
Further, the exploration hole is the hole NPTH.
Further, the upper surface of the resin plate further includes the green oil for protection circuit.
Further, the detection cavity surface is coated with golden finger.
Further, it is connected between two adjacent detection cavities by lead.
The one or more technical solutions provided in the utility model embodiment, at least have the following beneficial effects: this reality
A kind of pcb board with probe aperture is used with novel, substrate, layers of copper and resin plate is disposed with from bottom to up, further includes embedding
Detection cavity in resin plate further includes the exploration hole that layers of copper and substrate are connect and run through with detection cavity.To compared with the prior art
The scheme of detection hole location can only be set in one layer of pcb board, and the embodiment of the utility model runs through PCB by detection cavity and exploration hole
Plate provides hardware foundation for all layers of circuit in integrated test PCB, accelerates production efficiency.
Detailed description of the invention
The utility model is described in further detail with example with reference to the accompanying drawing.
Fig. 1 is a kind of cross-sectional view of pcb board with probe aperture of the utility model one embodiment；
Fig. 2 is a kind of top view of pcb board with probe aperture of the utility model another embodiment.
Specific embodiment
Currently, the pcb board number of plies as important spare part is also being stepped up, with the development of electronic product in order to right
The performance of pcb board is tested, and needs that probe aperture is arranged.Most of currently existing scheme is each layer of setting probe in pcb board
Hole, although being able to satisfy the demand of test, under efficiency is very low when the pcb board number of plies is more.
Based on this, the utility model uses a kind of pcb board with probe aperture, is disposed with substrate, copper from bottom to up
Layer and resin plate further include the detection cavity in resin plate, further include the spy that layers of copper and substrate are connect and run through with detection cavity
Gaging hole.To the scheme that detection hole location can only be arranged in one layer of pcb board compared with the prior art, the embodiment of the utility model passes through spy
It surveys chamber and exploration hole runs through pcb board, provide hardware foundation for all layers of circuit in integrated test PCB, accelerate production
Efficiency.
With reference to the accompanying drawing, the utility model embodiment is further elaborated.
- Fig. 2 referring to Fig.1, one embodiment of the utility model provide a kind of pcb board with probe aperture, comprising: base
Plate 1 and the layers of copper 2 for being pressed on 1 upper surface of substrate；It further include the resin plate 3 of pressing with 2 upper surface of layers of copper；
It further include detection cavity 4 and exploration hole 5, the detection cavity 4 is in resin plate 3, the exploration hole 5 and detection cavity 4
It is connected, the exploration hole 5 runs through layers of copper 2 and substrate 1.
Wherein, in the present embodiment, the detection cavity 4 can be the detection cavity of arbitrary shape, preferred side in the present embodiment
Shape detection cavity, and in resin plate 3.
Wherein, in the present embodiment, the detection cavity 4 is preferably bonded with layers of copper 2, so that it is guaranteed that electrical connection.
Further, in another embodiment of the utility model, the upper surface of the layers of copper 2 and the following table of detection cavity 4
It further include the radium-shine lead 6 for removing cull between face.
Wherein, in the present embodiment, since detection cavity 4 usually adopts the form manufacture of gong plate, inevitably understand cull,
In order to guarantee the connection between detection cavity 4 and layers of copper 2, radium-shine lead 6 is set between layers of copper 2 and resin plate 3, for using radium
It penetrates and understands cull.
Further, in another embodiment of the utility model, the exploration hole 5 is the hole NPTH.
Wherein, in the present embodiment, exploration hole 5 can be any form of hole, and the preferred hole NPTH in the present embodiment is that is, non-
Heavy copper hole.Since exploration hole 5 is for detecting, if the heavy copper of the inner wall of exploration hole 5, it is easy to cause the PCB between different layers
Route is first connected to, and leads to route transposition, to destroy pcb board.
Further, in another embodiment of the utility model, the upper surface of the resin plate 3 further includes for protecting
The green oil of route.
Further, in another embodiment of the utility model, 4 surface of detection cavity is coated with golden finger 7.
Further, in another embodiment of the utility model, connected between two adjacent detection cavities 4 by lead 8
It connects.
The above, the only preferred embodiment of the utility model, the utility model are not limited to above-mentioned implementation
Mode, as long as its technical effect for reaching the utility model with identical means, all should belong to the protection scope of the utility model.
