Abstract
The utility model relates to an inlayer drilling test PAD of rigid -flex board, including inner plating and outer plywood, the four corners of inner plating respectively is provided with the combination of a set of test hole, and every test hole combination sets of group has six test holes, be provided with the elliptical aperture on the outer plywood, the major axis length of elliptical aperture is 2 millimeters, the utility model discloses whether can detect the inlayer figure and bore partially, the defective work is discover early to the inspection drilling effect of being convenient for, improves production efficiency.
Description
Technical field
The utility model relates to a kind of circuit board test device, particularly relates to a kind of internal layer borehole test PAD of rigid-flex combined board.
Background technology
The rigid-flex combined board normally wiring board of more than three layers or three layers, because internal layer circuit needs boring, conventional method is generally the precision that mode by holing again after surveying harmomegathus coefficient improves internal layer boring, but whether internal layer holes, off normal cannot check out, thus result in fraction defective and raise.
In prior art, if the patent No. is 201020239933.3, the applying date is 2010.06.25 " a kind of positioning plate for drilling holes on circuit board ", and this utility model reduces production cost, due to the original discarded location-plate of recycling, has also greatly saved resource.But when this utility model still cannot solve outer boring, whether internal layer boring bores inclined problem, and outer boring can not observe directly internal layer borehole test PAD, and practicality has much room for improvement.
Utility model content
For the present situation of above-mentioned prior art, it is simple that technical problem to be solved in the utility model is to provide a kind of structure, and detection method is effective, can observe directly the test PAD of internal layer boring accuracy.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of internal layer borehole test PAD of rigid-flex combined board, comprises inner plating and lamina rara externa, it is characterized in that: the corner of described inner plating is respectively provided with one group of instrument connection combination; Described lamina rara externa is provided with elliptical aperture; After described inner plating and lamina rara externa are fitted, instrument connection combination is positioned at elliptical aperture.
Further, described instrument connection combination includes the first instrument connection, the second instrument connection, the 3rd instrument connection, the 4th instrument connection, the 5th instrument connection and the 6th instrument connection, and described first instrument connection, the second instrument connection, the 3rd instrument connection, the 4th instrument connection, the 5th instrument connection and the 6th instrument connection divide two rows symmetry arrangement.
Further, the aperture, minimum place of described first instrument connection, the second instrument connection, the 3rd instrument connection, the 4th instrument connection, the 5th instrument connection and the 6th instrument connection is 0.15 millimeter.
Further, the long axis length of described elliptical aperture is 2 millimeters.
Further, the spacing between described instrument connection combination is 0.1 millimeter.
Compared with prior art, the utility model has the advantage of: whether the utility model can detect inner figure and bore partially, be convenient to check drilling effect, find defective item early, enhance productivity.
Accompanying drawing explanation
Fig. 1 is structure chart after ectonexine of the present utility model laminating;
Fig. 2 is endothecium structure figure of the present utility model;
Fig. 3 is layer structure figure of the present utility model.
Embodiment
As Figure 1-3, a kind of internal layer borehole test PAD of rigid-flex combined board, comprises inner plating 1 and lamina rara externa 2, the corner of inner plating 1 is respectively provided with one group of instrument connection combination, often organize instrument connection combination and include the first instrument connection 11, second instrument connection 12, 3rd instrument connection 13, 4th instrument connection 14, 5th instrument connection 15 and the 6th instrument connection 16, first instrument connection 11, second instrument connection 12, 3rd instrument connection 13, 4th instrument connection 14, 5th instrument connection 15 is identical with the 6th instrument connection 16 size, aperture, minimum place is 0.15 millimeter, instrument connection combination monolateral larger than instrument connection 0.125 millimeter, therefore minimum test PAD size is 0.4 millimeter, spacing between instrument connection combination is 0.1 millimeter, six instrument connections divide two rows symmetry arrangement, upper row arranges three instrument connections, lower row arranges three instrument connections, lamina rara externa 2 is provided with elliptical aperture 21, the long axis length of elliptical aperture 21 is 2 millimeters, after inner plating 1 and lamina rara externa 2 are fitted, the first instrument connection 11, second instrument connection 12, the 3rd instrument connection 13, the 4th instrument connection 14, the 5th instrument connection 15 and the 6th instrument connection 16 included by instrument connection combination are all positioned at elliptical aperture 21.
When processing rigid-flex combined board, first etch out by internal layer borehole test PAD when inner plating does figure, lamina rara externa detect aperture of first being holed by skin comes outbreak out, and is fixed, hole after measuring internal layer harmomegathus again after ectonexine laminating by lamination.If the hole of boring in internal layer borehole test PAD partially, does not then show that the hole in inner figure is not bored partially yet, just can start boring in enormous quantities.Whether the utility model can detect inner figure and bore partially, is convenient to check drilling effect, finds defective item early, enhances productivity.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in foregoing embodiments, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.
