Abstract
The utility model relates to the electrical field, in particular to a PCB. The PCB comprises four corners, and the shape of one of the corners of the PCB is different from the shapes of the other three corners. By means of the PCB, the shape of one of the corners of the PCB is different from the shapes of the other three corners, so that operators can easily recognize whether the PCB is inversely placed, the circumstance of reworking or scrapping due to the reverse placing of the PCB is avoided, the cost is saved, and the work efficiency is improved.
Description
Technical field
The utility model relates to electricity field, particularly a kind of printed circuit board.
Background technology
General printed circuit board is a rectangle, is provided with location hole in four corners of printed circuit board usually, with arrange, position in the process of welding electric component with encapsulation process in play fixation.Because the operator is skilled inadequately in when location, perhaps distraction, the problem that can cause the printed circuit board direction to put back; And then causing that the direction of electric component misplaces in the printed circuit board, printed circuit board needs to make again, even scraps; Not only reduce operating efficiency, and increase cost; Carry out in the encapsulation process printed circuit board direction at electronic installation and put back and to cause this electronic installation normally not use, reduce product percent of pass.In addition, for satisfying the requirement of little encapsulation, the circuit board that tow sides all are furnished with electric component has appearred.Arranging, welding in the process of electric component; If on the front of printed circuit board, welded the due electric component of reverse side; Perhaps on the reverse side of system circuit board, weld positive due electric component, then possibly cause scrapping of electric component, printed circuit board.If will weld in the wrong circuit board input utilization, then may damage the circuit board that other are attached thereto.
The utility model content
The purpose of the utility model is: the problems referred to above to prior art exists provide a kind of and can discern the printed circuit board whether direction puts back.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of printed circuit board comprises four corners, and one of them corner shape of said printed circuit board and other three corner shapes are variant.One of them corner of said printed circuit board is provided with breach.
Preferably, one of them corner of said printed circuit board is provided with breach.
Preferably, four corners of said printed circuit board are provided with location hole, and said breach is arranged at the outside of this corner location hole.
Preferably, wherein three corners of said printed circuit board are provided with breach.
Preferably, four corners of said printed circuit board are provided with location hole, and said breach is arranged at the outside of this corner location hole.
In sum; Owing to adopted technique scheme, the beneficial effect of the utility model is: the printed circuit board of the utility model, and one of them corner shape and other three corner shapes are variant; Whether operating personnel can be easy to identification system circuit board and put back; Avoid printed circuit board because of putting back the situation of doing over again or scrapping, provided cost savings, improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the structural representation of embodiment 2.
Mark among the figure: 1-location hole, 2-rectangular indentation, 3-vee.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, four corners of the printed circuit board that present embodiment is enumerated are provided with location hole 1, and one of them corner of printed circuit board is provided with rectangular indentation 2, and said rectangular indentation 2 is arranged at the outside of this corner location hole 1 of printed circuit board.When the setting printed circuit board was correctly placed, the corner that is provided with rectangular indentation 2 was the bottom-right corner of printed circuit board.Like this, whether operating personnel can be easy to identification system circuit board and put back, and have avoided printed circuit board because of putting back the situation of doing over again or scrapping, and provide cost savings, and have improved operating efficiency.
As shown in Figure 2, four corners of the printed circuit board that present embodiment is enumerated are provided with location hole 1, and wherein three corners of printed circuit board are provided with vee 3, and said vee 3 is arranged at the outside of the location hole 1 of this corner of printed circuit board.When printed circuit board was correctly placed, the corner that is provided with vee 3 was respectively the corner, upper left side of printed circuit board, corner, lower left, corner, upper right side.Like this, whether operating personnel can be easy to identification system circuit board and put back, and have avoided printed circuit board because of putting back the situation of doing over again or scrapping, and provide cost savings, and have improved operating efficiency.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
