Abstract
The utility model discloses the anti-bite arbor of a kind of PCB Individual optical loci; be made up of Individual optical loci and the becket being surrounded on described Individual optical loci periphery; owing to being provided with becket in the periphery of Individual optical loci; this becket is the guard ring of this Individual optical loci; the electric current that this becket produces when can reduce Tin plating by stages, thus protection Individual optical loci is not stung eating away by tin.
Description
Technical field
The utility model belongs to printed circuit board arrangement field, be specifically related to a kind of electric current produced when reducing Tin plating by stages, thus protection Individual optical loci is not stung the Individual optical loci structure of eating away by tin.
Background technology
In printed circuit board (PCB) production process, conveniently circuit board processing, to produce and welding, need to arrange location hole and optical registration point on circuit boards, optical registration point mainly welds for contraposition.Independent PAD (optical registration point) on PCB, without wiring circuit contact, in depletion region, can produce high electric current instantaneously and cause copper to be stung erosion by tin during Tin plating, produce quality bad.
Utility model content
In order to solve the problem; the utility model provides the anti-bite arbor of a kind of PCB Individual optical loci; the high electric current that this PCB Individual optical loci anti-bite arbor produces when have employed beyond thought simple structure to reduce Tin plating by stages, thus protection Individual optical loci is not stung eating away by tin.
The utility model in order to the technical scheme solving its technical problem and adopt is:
The anti-bite arbor of a kind of PCB Individual optical loci, is made up of Individual optical loci and the becket being surrounded on described Individual optical loci periphery.
The utility model in order to the further technical scheme solving its technical problem and adopt is:
Say further, described Individual optical loci is Copper Foil point, and described becket is Copper Foil ring.
Preferably, the width (distance between the inside and outside circle of becket) of described becket is 0.3mm.
Preferably, described Individual optical loci is circular, and the spacing of described becket and described Individual optical loci is 1.086mm.
The beneficial effects of the utility model are: the anti-bite arbor of PCB Individual optical loci of the present utility model is made up of Individual optical loci and the becket being surrounded on described Individual optical loci periphery; the electric current that this becket produces when can reduce Tin plating by stages, thus protection Individual optical loci is not stung eating away by tin.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by way of specific instantiation, embodiment of the present utility model is described, those skilled in the art can understand advantage of the present utility model and effect easily by content disclosed in the present specification.The utility model also can be implemented in further, different ways, that is, under the category do not disclosed departing from the utility model, can give different modifications and change.
Embodiment: the anti-bite arbor of a kind of PCB Individual optical loci, as shown in Figure 1, is made up of Individual optical loci 1 and the becket 2 being surrounded on described Individual optical loci periphery.
Described Individual optical loci 1 is Copper Foil point, and described becket is Copper Foil ring.
The width (distance between the inside and outside circle of becket) of described becket 2 is 0.3mm.
Described Individual optical loci 1 is circular, and described becket 2 is 1.086mm with the spacing of described Individual optical loci 1.
