Abstract
The utility model relates to an offset testing system for secondary perforation of a circuit board, belonging to the field of circuit boards. The system comprises the circuit board, the circuit board is provided with a secondary hole which is perforated in a supplementary manner via a drilling machine, the four corners of the circuit board are respectively provided with four secondary-hole offset detection labels, each secondary-hole offset detection label comprises a circular copper layer and a circular copper ring which are both arranged on the circuit board, and the internal diameter of the circular copper ring is greater than the external diameter of the circular copper layer. The offset testing system manages and controls the offset degree of supplementary drilling via the secondary-hole offset detection labels on the circuit board, thereby improving the detection efficiency and economic benefit.
Description
Technical field
The utility model belongs to wiring board field, is specially a kind of wiring board and mends the secondary pore skew test macro boring.
Background technology
Printed-wiring board (PWB) is widely used in electronic product field, particularly on the consumer electronics product such as mobile phone, notebook computer.
Printed-wiring board (PWB) has to mend and bores secondary pore processing procedure in manufacturing process, because of job requirements, some client holes of subdrilling in the time of front boring processing procedure, through some after other after process operations (after making as copper face layer) get back to again boring processing procedure, mend again and bore some special drills, the hole that now two shot borehole processing procedures get out is just referred to as to mend bores secondary pore, and in the time mending brill, there will be unavoidably boring shift phenomenon, so that bring puzzlement to lower process operations.
Utility model content
The purpose of this utility model is to address the above problem, and provides a kind of secondary pore that can realize benefit brill to realize the test macro of fast detecting.
The technical scheme that realizes above-mentioned purpose is: wiring board is mended the secondary pore skew test macro boring, comprise wiring board, on wiring board, be provided with by boring board and supplement the secondary pore getting out, it is characterized in that: four jiaos of wiring board are respectively arranged with a secondary pore offset detection label, each secondary pore offset detection label comprises respectively setting round copper layer in the circuit board and circle copper ring, the internal diameter of circle copper ring is greater than the external diameter of round copper layer, the manhole that is provided with on circle copper ring and the wiring board of justifying between copper layer that drilling machine bench drill by getting out secondary pore goes out and gets out with secondary pore simultaneously, the diameter that the diameter of manhole is greater than round copper layer is less than the internal diameter of round copper ring, manhole edge equals the distance of manhole edge to circle copper layer external diameter to the distance of circle copper ring internal diameter, and equal secondary pore and allow the tolerance being offset.
Detection principle of the present utility model: behind the complete hole of secondary hole drill, personnel's range estimation, manhole covers on round copper ring or exposes middle round copper layer and can be judged to be skew.
The utility model is by arranging secondary pore offset detection label in the circuit board, and the drift rate management and control of holing while having realized existing benefit brill operation, provides detection efficiency, has improved economic benefit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is secondary pore offset detection label enlarged drawing.
Embodiment
As shown in Figure 1, the utility model comprises wiring board 1, on wiring board 1, be provided with by boring board and supplement the secondary pore 2 getting out, four jiaos of wiring board 1 are respectively arranged with a secondary pore offset detection label 3, each secondary pore offset detection label 3 comprises respectively the round copper layer 4 and the circle copper ring 5 that are arranged on wiring board 1, the internal diameter of circle copper ring 5 is greater than the external diameter of round copper layer 4, the manhole 6 that is provided with on circle copper ring 5 and the wiring board 1 of justifying between copper layer 4 that drilling machine bench drill by getting out secondary pore 2 goes out and gets out with secondary pore 2 simultaneously, the diameter that the diameter of manhole 6 is greater than round copper layer 4 is less than the internal diameter of round copper ring 5, manhole 6 edges equal the distance of manhole 6 edges to circle copper layer 4 external diameter to the distance of circle copper ring 5 internal diameters, and equal secondary pore 2 and allow the tolerance being offset.
