By adopting the technical scheme provided by the utility model, the difficulty and the time of design are reduced, the design efficiency is improved, and the manufacturing cost is relatively lowered.
Description
Technical field
The utility model relates to a kind of printed circuit board (PCB), and more body relates to a kind of printed circuit board (PCB) with optical alignment function.
Background technology
Along with printed circuit board (PCB) more and more develops toward the direction of densification and miniaturization, on circuit board, often have hundreds of even more electronic devices and components and holding wire.Wherein the optical alignment point is a kind of element that had not only had highly but also do not had electric attribute, provide optical alignment for equipment when being used for the element paster, to guarantee that the element paster can be located on the correct position, so the optical alignment point is a critical elements indispensable on the printed circuit board (PCB).And because the special role of optical alignment point, each optical alignment point is not covered by element in the process of element paster all the time, therefore must take bigger space, and wiring and components and parts can not be arranged in the certain limit around.
As from the foregoing, in the confined space of circuit board, should satisfy the high density layouts designing requirement, be the regional headspace of optical alignment point again, so since, increased board design difficulty and time, greatly influence design efficiency, and increased manufacturing cost relatively.
The utility model content
In view of the shortcoming of above-mentioned prior art, a purpose of the present utility model is to provide a kind of printed circuit board (PCB), in order to reduce board design difficulty and time, improves design efficiency, and reduces manufacturing cost relatively.
Reach other relevant purposes in order to achieve the above object, the utility model provides a kind of printed circuit board (PCB), it is characterized in that comprising at least: screw hole, screw hole forbid that wiring is regional, the screw hole taboo is established element area and optical alignment point.Wherein, this screw hole forbid connecting up the zone be located at this screw hole around and surround screw hole; This screw hole prohibit establish element area be located at this screw hole around and surround screw hole, and this screw hole prohibit establish element area and this screw hole forbid connecting up the zone have overlap regional; This optical alignment point is located at this screw hole and is prohibited that to establish forbid connecting up this overlapping in zone of element area and this screw hole regional.
Aforementioned printed circuit board (PCB) of the present utility model in one embodiment, this screw hole is prohibited and is established element area and be included in this screw hole and forbid connecting up in the zone.This optical alignment point is located at around this screw hole.
As mentioned above, the principal character of printed circuit board (PCB) of the present utility model is prohibited and is established element area and forbid the regional overlapping zone of connecting up with this screw hole for the optical alignment point being located at this screw hole, in the confined space of printed circuit board (PCB), both satisfied the high density layouts designing requirement, realized purpose again for the regional headspace of laying optical alignment point.So, not only reduced the board design difficulty, also saved design time, greatly improved design efficiency, and then reduced the manufacturing cost of product.

Embodiment
Below be by specific instantiation execution mode of the present utility model to be described, those skilled in the art can understand other advantages of the present utility model and effect easily by the content that this specification disclosed.The utility model also can be implemented or be used by other different instantiations, and the every details in this specification also can be based on different viewpoints and application, carries out various modifications and change under the spirit of the present utility model not deviating from.
Moreover, the following drawings is the schematic diagram of simplification, and basic conception of the present utility model only is described in a schematic way, thereby only show the element relevant in the accompanying drawing but not component number, shape and size drafting when implementing according to reality with the utility model, kenel, quantity and the ratio of each element can be a kind of random change during its actual enforcement, and its component placement kenel may be more complicated.
See also Fig. 1, it is the schematic diagram of the utility model printed circuit board (PCB).As shown in the figure, the utility model provides a kind of printed circuit board (PCB) 1, comprises at least: screw hole 11, screw hole are forbidden that wiring zone 12, screw hole are prohibited and are established element area 13 and optical alignment point 14.
Need to prove, in concrete execution mode, on same printed circuit board, can include a plurality of screw holes 11, a plurality of screw hole and forbid that wiring zone 12, a plurality of screw hole are prohibited and establish element area 13 and a plurality of optical alignment point 14.But for convenience of description, each assembly of printed circuit board (PCB) 1 in the present embodiment is that example is described with single number temporarily all, but non-ly limits interest field of the present utility model with this.
This screw hole 11 is arranged on the printed circuit board (PCB) 1, fixes this printed circuit board (PCB) 1 in order to cooperate screw (not shown) in subsequent manufacturing processes.
Circuit and element on this printed circuit board (PCB) 1 of screw scratch, thereby definition has screw hole to forbid that wiring zone 12 and screw hole are prohibited to establish element area 13 on this printed circuit board (PCB) 1.This screw hole forbid connecting up zone 12 be located at this screw hole 11 around and surround screw hole 11; This screw hole prohibit establish element area 13 be located at this screw hole 11 around and surround screw hole 11, and this screw hole is prohibited and is established element area 13 and forbid that with this screw hole wiring zone 12 has the zone of overlapping.
In the present embodiment, this screw hole is prohibited and is established element area 13 and be contained in this screw hole and forbid in the wiring zone 12, and in other words, promptly this screw hole is prohibited and established element area 13 and this screw hole forbid connecting up overlapping zone in zone 12 and equal this screw hole and prohibit and establish element area 13.
This optical alignment point 14 is located at this screw hole and is prohibited that to establish forbid connecting up this overlappings in zone 12 of element area 13 and this screw hole regional.In the present embodiment, because this screw hole is prohibited and is established element area 13 and this screw hole forbid connecting up overlapping zone in zone 12 and equal this screw hole and prohibit and establish element area 13, thereby this optical alignment point 14 is located at this screw hole and is prohibited and establish in the element area 13, particularly, this optical alignment point 14 is located at around this screw hole 11.
In printed circuit board (PCB) of the present utility model, this screw hole taboo is established element area and this screw hole is forbidden the regional overlapping zone of connecting up owing to the optical alignment point is located at, so the effect of location can be provided when paste solder printing and element paster manufacture process, to guarantee the accuracy of paste solder printing and element paster, in the confined space of printed circuit board (PCB), to have reached the high density layouts designing requirement.So, not only reduced the board design difficulty, also saved design time, greatly improved design efficiency, and then reduced the manufacturing cost of product.Therefore, use the utility model and can overcome aforementioned many shortcomings of prior art, and have high industrial utilization really.The foregoing description is illustrative principle of the present utility model and effect thereof only, but not is used to limit the utility model.Those skilled in the art all can be under spirit of the present utility model and category, and the foregoing description is modified and changed.Therefore, to those skilled in the art, do not modify or change breaking away from all equivalences of being finished under spirit that the utility model discloses and the technological thought, must be contained by claim.
