Problems solved by technology
[0005] In the existing technology, the ability to detect back-drilling mainly relies on slice detection of boards after back-drilling processing. Each board needs to be confirmed by a large number of slices. Not only is the detection efficiency very low, but the process is costly, time-consuming and laborious.

The invention discloses a device for testing back drill processing performance , which is provided with a plurality of conductive test terminals on a PCB board, the connecting wires between two test terminals, and the hole to be drilled in back drill performance test disposed between the test terminals. The wire is arranged at a preset position close to the hole to be drilled in back-drill performance test, so that after the back-drilling process, if the positioning is inaccurate, the wire connection is broken to stop the power supply to the branch of the wire circuit. Therefore, by using thedevice for testing back drill processing performance provided by the present invention, it is only necessary to detect the connection condition of the wires, and the accurate positioning of the backdrilling processing positioning on the back drilling capability test via hole near the wire can be obtained. Compared with the prior art, it is more convenient and faster. The invention also discloses a method for testing back drill processing performance, which has the beneficial effects as previously described.
Description
technical field [0001] The invention relates to the field of PCB board processing, in particular to a detection device and method for back drilling processing capability. Background technique [0002] With the extensive development of cloud computing and big data, informatization has gradually covered all fields of society, the amount of network data has increased sharply, and the signal speed has become faster and faster. The original broad design rules are no longer enough to guarantee the signal quality. This will inevitably cause all Stricter requirements for design elements. For example, the introduction of new materials emerges one after another, the new manufacturing process greatly reduces production costs, and the performance has also been greatly improved. This undoubtedly increases the design density, and the trend of miniaturization is also partly benefited from this. [0003] When designing wiring in a miniaturized crowded space, usually the signal wiring canno...
