Summary of the invention
In view of this, the technical problems to be solved in the utility model is that one stops Lou gong wiring board, raising detection efficiency, and the wiring board that prevents reducing heavy industry amount leaks gong plate structure.
In order to solve the problems of the technologies described above, the utility model adopts following scheme to realize: one prevents wiring board from leaking gong plate structure, and comprise the wiring board body being coated with anti-solder ink, described wiring board body is provided with Luo Cao district and line areas; Be provided with the leakproof gong structure preventing CNC equipment from leaking the Luo Cao district of gong wiring board in described Luo Cao district, this leakproof gong structure is positioned at the Luo Cao district near line areas; Described leakproof gong structure comprises solder mask window district, is arranged on the test point in solder mask window district and is communicated with the connecting line of two test points; Test point is arranged in the region at place, solder mask window district.
Wherein, described solder mask window district and test point are circle, and the circle in solder mask window district is identical with the circle of test point, and the diameter in solder mask window district is greater than the diameter of test point.
Wherein, described test point is fool proof PAD.
Wherein, the diameter of described fool proof PAD is more than or equal to 0.3mm.
Wherein, the diameter of described fool proof PAD is 0.5mm; The diameter in solder mask window district is 0.6mm.
Wherein, the live width of described connecting line is 0.2mm.
Compared with prior art, the utility model improves from the structure of wiring board, arrange in the Luo Cao district of wiring board and be provided with leakproof gong structure with corresponding section, testing needle position on measurement jig, and make measurement jig can be quick by this leakproof gong structure, detect whether the Luo Cao district of wiring board body is removed by CNC equipment gong accurately, effectively can stop wiring board and leak gong phenomenon, whether improve the Luo Cao district of detection line plate body by the efficiency at gong place, reduce labour to drop into, reduce the labour intensity of workman, save production cost, can also effectively prevent in visual examination process simultaneously, because human negligence causes the wiring board in Lou Luoluocao district to flow in next step operation, reduce heavy industry wiring board amount, shorten the production time of wiring board, improve the quality of production efficiency and wiring board.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A portion enlarged drawing in Fig. 1.
Embodiment
In order to allow those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further elaborated.
As depicted in figs. 1 and 2, one prevents wiring board from leaking gong plate structure, and comprise the wiring board body 1 being coated with anti-solder ink, this wiring board body is PNL plate, is namely linked together by two independent wiring boards.Described wiring board body 1 is provided with needs the Luo Cao district 11 that gong in CNC equipment removes and the line areas 12 stayed on wiring board body.Confession CNC equipment gong wiring board body between Luo Cao district and line areas realizes the gong printed line 14 that Luo Cao district is separated with line areas, and this gong printed line is the circuit that in CNC equipment, gong cutter carries out feed to wiring board body.Conveniently, accurately the Luo Cao district of detection line plate body whether in the CNC equipment course of processing gong remove, in described Luo Cao district 11, be provided with the leakproof gong structure 13 preventing CNC equipment from leaking the Luo Cao district of gong wiring board, this leakproof gong structure 13 is positioned near gong printed line 14.Described leakproof gong structure 13 comprises solder mask window district 131, test point 132 and connecting line 133, and connecting line 133 is communicated with and two test points 132.Wherein solder mask window district 131 and test point 132 are circle, and the circle in solder mask window district 131 is identical with the circle of test point 132, and the diameter in solder mask window district 131 is greater than the diameter of test point 132.Described test point 132 is arranged in solder mask window district 131, and whether gong removes to make wiring board can detect it in measurement jig.In order to improve testing efficiency, described test point is fool proof PAD.
In order to improve the testing efficiency of measurement jig to the wiring board after removing through CNC equipment gong, the size of described fool proof PAD determines according to the size in Luo Cao district, and the diameter of fool proof PAD is more than or equal to 0.3mm.
In order to make the testing needle of measurement jig to test wiring board fast and accurately, improve detection efficiency, the diameter of described fool proof PAD is 0.5mm; The diameter in solder mask window district is 0.6mm; The live width of described connecting line 133 is 0.2mm.
During test, wiring board body is put into measurement jig and is tested, when the intrinsic Luo Cao district of wiring board by CNC equipment gong except time, the testing needle of measurement jig can not conducting, now illustrates that wiring board body Zhong Luocao district is removed by gong; Wiring board body is put into measurement jig and is tested, and when the intrinsic Luo Cao district of wiring board is not removed by CNC equipment gong, the testing needle conducting of measurement jig, now illustrates that wiring board body Zhong Luocao district is not removed by gong, now, is taken out by wiring board and carries out heavy industry.
Above-described embodiment is only wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection range of the present utility model.
