Abstract
The utility model discloses a PCB makeup on no technology limit, it is including a plurality of cell boards, a plurality of be equipped with the link bit between the cell board and drag for groove, every the outside edge of cell board all is equipped with tin stove fixture hole, mutually supports with tin stove fixture post in tin stove fixture hole, the beneficial effects of the utility model are that: set up tin stove fixture hole at the outside of cell board edge, get rid of the technology limit, mutually support with tin stove fixture post crossing tin stove process in the PCB makeup, realize can not taking place the displacement to the accurate location of PCB makeup to improve the precision and the stability of device assembly, compare in originally seting up the locating hole at the technology edge, saved the manufacturing process limit and got rid of the raw materials and the equipment on technology limit, cost reduction, environmental protection more.
Description
Technical field
This utility model is related to a kind of PCB layouts, specifically a kind of PCB layouts without technique edges.
Background technology
Fig. 1 is referred to, 4 cell boards are included in traditional PCB printed circuit board (PCB)s, the outside of cell board is provided with width and is
The technique edges of 3mm, offer the fixture positioning hole of a diameter of 1.5mm on technique edges, technique edges are placed on chip mounter rail, make spelling
Version can pass through stannum stove paster, and advantage is to pick and place conveniently；After the completion of having the disadvantage this technique edges paster, place is scrapped by a point plate
Reason, because PCB printed circuit board (PCB)s are mainly made up of copper-clad plate, Copper Foil and anti-solder ink, one is significant wastage economically, and two are
It is unfavorable for environmental protection.
The content of the invention
The purpose of this utility model is to provide a kind of PCB layouts without technique edges, to solve above-mentioned background technology in carry
The problem for going out.
For achieving the above object, this utility model provides following technical scheme：
A kind of PCB layouts without technique edges, including multiple cell boards, are provided with connection position and drag between multiple cell boards
Groove, is equipped with stannum stove fixture positioning hole in the outer side edges of each cell board, stannum stove fixture positioning hole is positioned with stannum stove fixture
Post cooperates.
As further program of the utility model：The quantity of the cell board is preferably 4.
As this utility model further scheme：The length of the connection position is preferably 6mm.
As this utility model further scheme：The width for dragging for groove is preferably 1.3mm.
As this utility model further scheme：The stannum stove fixture positioning hole is matched somebody with somebody with stannum stove fixture locating dowel gap
Close, preferably, a diameter of 1.6mm of stannum stove fixture positioning hole 2, a diameter of 1.5mm of stannum stove fixture locating dowel.
Compared with prior art, the beneficial effects of the utility model are：Stannum stove fixture positioning hole is opened in into cell board
In outer side edges, technique edges are removed, cooperated with stannum stove fixture locating dowel in stannum stove process excessively in PCB layouts, realize spelling PCB
The precise positioning of version, will not be subjected to displacement, so as to improve the precision and stability of device assembling, compared to being originally opened in technique
Location hole on side, saves manufacturing process side and removes the raw material and equipment of technique edges, and cost is reduced, more environmentally-friendly.
Description of the drawings
Fig. 1 is the structural representation of the PCB layouts for having technique edges in prior art.
Fig. 2 is a kind of structural representation of the PCB layouts without technique edges.
In figure：1- cell boards, 2- stannum stove fixture positioning holes, 3- connection positions, 4- drag for groove.
Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Fig. 2, a kind of PCB layouts without technique edges, including multiple cell boards 1 are referred to, is set between multiple cell boards 1
There is connection position 3 and drag for groove 4, connection position can increase layout intensity, in case there is deformation, warpage during stannum stove is crossed in PCB layouts
Deng abnormal phenomena, cause the bad problem such as paster rosin joint, short circuit, connection position position to avoid associated mechanisms part, otherwise cannot enter
Row dividing techniques, are equipped with stannum stove fixture positioning hole 2 in the outer side edges of each cell board 1, in PCB layouts stannum stove mistake is being crossed
Journey cooperates with stannum stove fixture locating dowel, realizes the precise positioning to PCB layouts, will not be subjected to displacement, so as to improve device
The precision and stability of assembling, compared to the location hole being originally opened on technique edges, saves manufacturing process side and removes work
The raw material and equipment on skill side, it is more cost-effective.
The quantity of the cell board 1 is preferably 4.
The length of the connection position 3 is preferably 6mm.
The width for dragging for groove 4 is preferably 1.3mm.
The stannum stove fixture positioning hole 2 coordinates with stannum stove fixture locating dowel gap, preferably, stannum stove fixture positioning hole 2
A diameter of 1.6mm, a diameter of 1.5mm of stannum stove fixture locating dowel.
Operation principle of the present utility model is：Stannum stove fixture positioning hole 2 is opened in the outer side edges of cell board 1, is removed
Technique edges, cooperate in stannum stove process excessively in PCB layouts with stannum stove fixture locating dowel, realize the precise positioning to PCB layouts,
Will not be subjected to displacement, so as to improve the precision and stability of device assembling, compared to the location hole being originally opened on technique edges,
Save manufacturing process side and remove the raw material and equipment of technique edges, cost is reduced, more environmentally-friendly.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can be with the premise of without departing from this patent objective
Make a variety of changes.
