Abstract
The invention relates to a printed circuit board (PCB) with stamp holes, which comprises a PCB base plate, and an effective plate area of the base plate is connected with edge materials through the stamp holes. The stamp holes are formed by connecting strip holes and small circular holes at intervals. The number of the small circular holes is 2 to 6. The PCB with stamp holes solves the problem of irregular burrs and being easy to hurt people caused by releasing of the edge materials of a PCB and is very easy and convenient in a machining process.
Description
Technical field
The present invention relates to a kind of pcb board with stamp hole.
Background technology
Pcb board is exactly a printed circuit board (PCB), almost can appear in the middle of each electronic equipment.And electronic component just is set on the pcb board of different sizes.Along with electronic equipment becomes increasingly complex, the part that needs is more and more, and circuit and part on the pcb board are also more and more intensive.This plate is heat insulation by insulation, also unbending material constitutes substrate; The tiny line material that can see on the surface is a Copper Foil; Originally Copper Foil is to cover on the whole plank, and part is etched and disposes in manufacture process, and the part that stays has just become netted tiny circuit.These circuits are known as lead or claim wiring, and are used to provide the circuit connection of part on the pcb board.
Usually all be provided with groove between the corner of the actual use of nothing of existing pcb board and effective plate district or the feature board district; When the finished product pcb board pulls open use along above-mentioned groove; It is outside protruding usually to have stayed burr; Not only have a strong impact on the attractive in appearance of pcb board, but also be easy to scratch operating personnel's limbs, the more important thing is to make pcb board be difficult to snap in complete machine.
Summary of the invention
The technical problem that the present invention will solve is: a kind of pcb board with stamp hole is provided
The technical solution adopted for the present invention to solve the technical problems is: a kind of pcb board with stamp hole, comprise the PCB substrate, and connect through stamp hole between effective plate district of described substrate and the rim charge.Described stamp hole is formed by connecting strip hole and small sircle hole at interval.The number of described small sircle hole is 2～6.
The invention has the beneficial effects as follows, solved the defective that exists in the background technology, overcome the pcb board rim charge and pulled from being to cause burr uneven, the problem of hurting sb.'s feelings easily again, and also the course of processing is very simple and easy.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the preferred embodiments of the present invention.
Embodiment
Combine accompanying drawing and preferred embodiment that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of pcb board with stamp hole as shown in Figure 1 comprises the PCB substrate, connects through stamp hole 1 between effective plate district of described substrate and the rim charge.Described stamp hole is formed by connecting strip hole 11 and small sircle hole 12 at interval.The number of described small sircle hole is 3.The strip hole two ends have the segment bending 11-1 in the effective plate of deflection district.
What describe in the above specification is embodiment of the present invention; Various not illustrating constitutes restriction to flesh and blood of the present invention; Under the those of ordinary skill of technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
Claims (3)
1. the pcb board with stamp hole comprises the PCB substrate, it is characterized in that: connect through stamp hole between effective plate district of described substrate and the rim charge.
2. a kind of pcb board with stamp hole as claimed in claim 1, it is characterized in that: described stamp hole is formed by connecting strip hole and small sircle hole at interval.
3. a kind of pcb board with stamp hole as claimed in claim 2 is characterized in that: the number of described small sircle hole is 2～6.
