Abstract
The utility model discloses the pcb board with contraposition target, body including sandwich construction, punching through hole is provided with each layer same position of body, the punching lead to the hole site is provided with the contraposition target of formed objects, described body one end middle part is provided with two punching through holes, used as positioning hole, for the body of sandwich construction to be positioned, described two positioning holes have certain interval in-between, other end centre position is provided with a punching through hole, make direction hole to use, for by the further exactitude position of body.There is the pcb board of contraposition target to be applied to X-ray machine drilling contraposition for this, the body of sandwich construction is positioned using positioning hole, utilization orientation hole is further by body exactitude position, suitable for the situation that desired size during silk screen printing process is larger, accuracy is high simultaneously, and operating efficiency is further lifted.
Description
Technical field
The utility model is related to the pcb board commonly used in a kind of electronic equipment, the specially pcb board with contraposition target, suitable
Exactitude position is carried out for X-ray machine drilling.
Background technology
PCB can be divided into single sided board, dual platen, four laminates, six laminates and other multilayers according to the wiring board number of plies
Wiring board.PCB develops into two-sided, multilayer and flexibility from individual layer, and remains on respective development trend.Due to
Constantly develop to high accuracy, high density and high reliability direction, constantly reduce volume, reduce cost, improve performance so that
PCB remains in that powerful vitality in the development engineering of future electronic equipment.At present, PCB plates silk-screen
Production model has many kinds, including a wet film alignment process, semi-automatic silk screen printing process and full automatic line production model, but respectively
The production size planted required by production model is different, and the size especially for wet film and full automation production technology requires larger,
The deviation of screen printing device precision and silk screen shrinkage is easily caused circuit, between welding resistance and character layer it is not of uniform size with
And deviation problem, so that the contraposition to each layer causes trouble.
Utility model content
The purpose of this utility model is to provide the contraposition during the pcb board with contraposition target, solution silk screen printing process
Problem, is positioned the body of sandwich construction using positioning hole, and utilization orientation hole is further by body exactitude position, raising pair
Position accuracy, further improves operating efficiency.
To achieve the above object, the utility model provides following technical scheme：Pcb board with contraposition target, including it is many
Punching through hole is provided with the body of Rotating fields, each layer same position of body, the punching lead to the hole site is provided with identical big
Small contraposition target, described body one end middle part is used provided with two punching through holes as positioning hole, for by sandwich construction
Body positioned, described two positioning holes in-between have certain interval, other end centre position provided with one punching
Through hole processed, makees direction hole and uses, for by the further exactitude position of body.
It is preferred that, a quarter at intervals of the body width of described two positioning holes in-between.
It is preferred that, the punching through hole is bolt hole.
Compared with prior art, the beneficial effects of the utility model are：
There is the pcb board of contraposition target to be applied to X-ray machine drilling contraposition for this, be entered the body of sandwich construction using positioning hole
Row positioning, utilization orientation hole is further by body exactitude position, it is adaptable to the larger situation of desired size during silk screen printing process,
Accuracy is high simultaneously, and operating efficiency is further lifted.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- bodies, 2- punching through holes, 3- contraposition targets.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：Pcb board with contraposition target, including sandwich construction
Body 1, punching through hole 2 is provided with described 1 each layer of same position of body, the position of punching through hole 2 is provided with formed objects
Contraposition target 3, one end middle part of body 1 uses provided with two punching through holes 2 as positioning hole, for by multilayer knot
The body 1 of structure is positioned, and described two positioning holes have certain interval in-between, and described two positioning holes are in-between
The a quarter at intervals of the body width, other end centre position makees direction hole and uses provided with punching through hole 2,
For by the further exactitude position of body.
In the present embodiment, the punching through hole 2 is bolt hole.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
