Description
Technical field
The utility model belongs to pcb board manufacturing technology field, more particularly, relates to the pcb board of carving fool proof test point with V.
Background technology
Extensively universal along with electronic product, to the demand of printed circuit board (PCB) also in continuous increase.In order to tackle the ever-increasing market demand, reduce manufacturing cost simultaneously, conventionally on a large-area substrate, adopt array way to produce a plurality of circuit units with standalone feature, again that each circuit unit is separated during use; For the ease of split circuit unit, currently used mode is: at large-area substrate, by packing factory, completed after encapsulation, utilize V to carve cutting machine and on circuit board, cut out V cutting along predetermined cutting path, during use, V cutting along well cutting is separated by circuit unit, thereby forms the circuit unit with standalone feature.
When utilizing V quarter (being that V carves) cutting machine to cut V cutting to pcb board, must keep having between the upper and lower edge of a knife suitable spacing and accurately aim at, make that center is remaining thickly can support assembling operation also will conveniently fracture, at present not circuit board after can carving V carries out the method for effect detection, staff is just difficult to judge whether pcb board misses V carving technology flow process, increase the fraction defective of product, affected the prestige of product.
Therefore, be necessary to design a kind of pcb board with fool proof test point, check pcb board whether to have the V of carrying out to carve flow process.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide a kind of pcb board of carving fool proof test point with V, and it has facilitated pcb board to carry out the detection that V carves flow process.
To achieve these goals, the technical scheme that the utility model adopts is as follows:
A kind of pcb board of carving fool proof test point with V, comprise PCB mainboard and be etched on described PCB mainboard the conductive layer with electronic circuit, described PCB mainboard is provided with at least one fluting, described fluting is separated out at least one daughter board by described PCB mainboard, between described daughter board and described PCB mainboard, by connecting portion, be connected, described connecting portion is provided with fool proof test section; Described fool proof test section comprises the connection copper cash that detects hole and connect described detection hole.
Further, described connecting portion has 2, is rectangular configuration.
Further, described connecting portion is insulating barrier.
Further, described detection hole comprises the first detection hole, the second detection hole, and described the first detection hole, second is detected hole and be arranged in parallel.
Further, described connection copper cash is the inverted trapezoidal structure of an end opening, and it comprises the first oblique line, straight line and the second oblique line, and described the first oblique line and described first detects hole and is connected, and described the second oblique line and described second detects hole and is connected.
Further, described straight line is embedded in PCB mainboard.
Further, described straight line is connected with described the first oblique line, described the second oblique line respectively.
Than prior art, the beneficial effect that the utility model is carved the pcb board of fool proof test point with V is:
V by pcb board carves region division fool proof and detects aperture, between aperture, by circuit, is communicated with, and when pcb board has the V of carrying out carving technology V to be carved into, the circuit between aperture is carved disconnected, and during detection, open circuit in two holes; When pcb board carries out V quarter or V, not carving when not in place, is path between aperture; Its reasonable in design, cost of manufacture is low, detection efficiency is high, directly by current probe, can detect pcb board V carving technology situation, simple to operate, data are reliable.
Accompanying drawing explanation
Fig. 1 is that the utility model is carved the structural representation of the pcb board of fool proof test point with V;
Fig. 2 is that the utility model is with the structural representation of the fool proof test section of the pcb board of V fool proof test point at quarter.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of pcb board of carving fool proof test point with V, comprise PCB mainboard 1 and be etched on described PCB mainboard 1 conductive layer 2 with electronic circuit, PCB mainboard 1 is provided with a fluting, fluting is separated out 1 daughter board 3 by PCB mainboard 1, between daughter board 3 and PCB mainboard 1, by connecting portion 5, be connected, connecting portion 5 is provided with fool proof test section 5; Connecting portion 5 has 2, is rectangular configuration; Connecting portion 5 is insulating barrier, and such first detects that hole 501 and second just detects between hole 502 not can own conducting; Fool proof test section 5 comprises the first detection hole 501, the second detection hole 502 and is connected copper cash, connects the inverted trapezoidal structure that copper cash is an end opening; Connect copper cash and comprise that the first oblique line 503, straight line 504 and the second oblique line 505, the first oblique lines 503 and first detect hole 501 and are connected, the second oblique line 505 and second detects hole 502 and is connected; Straight line 504 is embedded in PCB mainboard 1; Straight line 504 is connected with the first oblique line 503, the second oblique line 505 respectively; The first centre-to-centre spacing that detects hole 501 and the second detection hole 502 is 100mil, and both radiuses are all 40mil, and the live width that connects copper cash is 6mil, and the V of straight line 504 distance P CB mainboards 1 carves limit 4mil; The first oblique line 503 is 65 ° with horizontal counterclockwise angle.
The utility model detects aperture by carving region division fool proof at the V of pcb board, between aperture, by circuit, is communicated with, and when pcb board has the V of carrying out carving technology V to be carved into, the circuit between aperture is carved disconnected, and during detection, open circuit in two holes; When pcb board carries out V quarter or V, not carving when not in place, is path between aperture; Its reasonable in design, cost of manufacture is low, detection efficiency is high, directly by current probe, can detect pcb board V carving technology situation, simple to operate, data are reliable.
