Description
Technical field
The utility model relates to circuit board, specifically refers to a kind of board structure of circuit of realizing character error measure.
Background technology
In circuit board fabrication industry, need to stamp character in circuit board top, along with the integrated level of circuit board is more and more higher, can not there is deviation in the character of plate face.How to realize character precision, in the prior art, can only rely on artificial location, when occurring that character has not timing of error, be also difficult to find, cause product fraction defective high, can not meet client's demand.
Utility model content
The purpose of this utility model be to provide a kind of character locating precisely, unification, uniform specification, the board structure of circuit of realizing character error measure that rate of finished products is high.
To achieve these goals, the utility model is designed a kind of board structure of circuit of realizing character error measure, it comprises circuit board and the broken part that is arranged on circuit board both sides, and described broken part is provided with Fang Han Copper pad, is provided with character error measure ring in the periphery of Fang Han Copper pad.
The cross section of described Fang Han Copper pad is circular.
The upper and lower side of described broken part is respectively equipped with Fang Han Copper pad.
The periphery of described Fang Han Copper pad is provided with three character error measure rings, and the internal diameter of these three character error measure rings is ascending, concentric with Fang Han Copper pad.
The internal diameter of described three character error measure rings is respectively 44mil, 48mil, 52mil, is respectively 2mil, 4mil, 6mil so measure the monolateral deviation of ring.
The board structure of circuit that the utility model is realized character error measure has following beneficial effect:
1, can be easy to check the character margin of error, and confirm that whether position is correct, be beneficial to timely correction,
Reduce product bad;
2, can reduce the temporal waste of manpower and materials that defective products heavy industry brings, reduce to save and produce
Cost;
3, can improve product yield, meet client to quality and the demand of the phase of friendship, can improve the competitiveness of company.
brief description of the drawings:
Fig. 1 is the schematic diagram that the utility model is realized the board structure of circuit of character error measure.
Embodiment
For the ease of those skilled in the art's understanding, below in conjunction with specific embodiment and accompanying drawing, structural principle of the present utility model is described in further detail.
As shown in Figure 1, a kind of board structure of circuit of realizing character error measure, it comprises circuit board 1 and the broken part 2 that is arranged on circuit board 1 both sides, described broken part 2 is provided with Fang Han Copper pad 3, in the periphery of Fang Han Copper pad 3, is provided with character error measure ring 4.
As shown in Figure 1, the cross section of described Fang Han Copper pad 3 is circular.
As shown in Figure 1, the upper and lower side of described broken part 2 is respectively equipped with Fang Han Copper pad 3.
As shown in Figure 1, the periphery of described Fang Han Copper pad 3 is provided with three character error measure rings 4, and the internal diameter of these three character error measure rings 4 is ascending, concentric with Fang Han Copper pad 3.
As shown in Figure 1, the internal diameter of described three character error measure rings 4 is respectively 44mil, 48mil, 52mil, is respectively 2mil, 4mil, 6mil so measure the monolateral deviation of ring.
PCB finishes circuit or covers anti-welding welding resistance ink after developing, and exposes the various shapes that mount for plug-in unit on plate face and big or small copper billet general designation pad.
The course of work of board structure of circuit that the utility model is realized character error measure is as follows: when character error measure ring manufacturing technology the 1st step is exactly deisgn product in 2(break edge, each shipment sheet broken part) 1 anti-welding copper pad of circle that size is 40mill of four jiaos of each designs; 3 connected character error measure rings of 4 each designs in the anti-welding copper pad of circle position on circuit board, the 1st ring internal diameter 44mil the 2nd ring internal diameter 48mil the 3rd ring internal diameter 52mil, be respectively 2mil so measure the monolateral deviation of ring, 4mil, 6mil, require precisely highly, use this to design in self-inspection, can significantly reduce the bad of product; After character printing, can measure the character position margin of error by character error measure ring: if copper pad is in the 1st ring centre position, represent that character does not have error; If copper PAD and the 1st ring are tangent, represent character error 2mil; With the tangent expression error 4mil of the 2nd ring; With the tangent expression error 6mil of the 3rd ring; If copper PAD represents character error 3mil in the 1st ring and the 2nd ring centre position, if represent character error 5mil in the 2nd ring and the 3rd ring centre position, can judge with 10 times of magnifying glasses.
The above, be only preferred embodiment of the present utility model, not the utility model done to any pro forma restriction; The those of ordinary skill of all industry all can be implemented the utility model with the above shown in by specification accompanying drawing swimmingly; But all those skilled in the art are not departing within the scope of technical solutions of the utility model, can utilize disclosed above technology contents and a little change, the modification of making and the equivalent variations developing, be equivalent embodiment of the present utility model; Meanwhile, the change of any equivalent variations that all foundations essence technology of the present utility model is done above embodiment, modification and differentiation etc., within all still belonging to the protection range of the technical solution of the utility model.
