Abstract
The utility model relates to a circuit board having a multilayer board (having more than four layers) stitching with asymmetric flat plates on outer layer. The circuit board includes the multilayer board. First areas are arranged on a front and a back surface of the multilayer board respectively. A first flat plate and a second flat plate are arranged correspondingly in the first areas on the front and back surface of the multilayer plate. Rivet holes are arranged in corresponding positions of the multilayer board, the first flat plate and the second flat plate. The utility model aims to overcome shortcomings in the prior art and provides a circuit board having a simple structure and capable of stitching layers fixedly.
Description
[technical field]
The utility model relates to the outer wiring board of the asymmetric tabula rasa of pressing again of a kind of multi-layer sheet (more than 4 layers).
[background technology]
Along with miniaturization, the high performance of electronic equipments, this just requires electronic device can realize the high density assemblingization, and in order to realize this high density assemblingization, wiring board develops towards multiple stratification.Yet in order to meet the different needs, as at multi-layer sheet skin pressing one deck FR-4 tabula rasa again, problem such as the PP gummosis is very big after interformational sliding when prior art can produce pressing, the pressing does not reach quality requirements.
Wherein FR-4 is a kind of code name of flame resistant material grade; The FR-4 tabula rasa is that a kind of electrical insulation capability is stable, good planeness, smooth surface, no pit, the high-performance electronic insulating products of thickness deviation standard.
The utility model is exactly to make in view of the situation.
[utility model content]
The utility model has overcome the deficiency of prior art, provides a kind of simple in structure, can make the fixedly wiring board of pressing of interlayer.
The utility model adopts following technical scheme for solving the problems of the technologies described above:
A kind of multi-layer sheet skin is the wiring board of the asymmetric tabula rasa of pressing again; Include multi-layer sheet; Be respectively equipped with the first area on described multiple-plate positive and negative two sides; On the first area on the positive and negative two sides of multi-layer sheet, be correspondingly provided with first tabula rasa, second tabula rasa, it is characterized in that: be provided with rivet hole in described multi-layer sheet, first tabula rasa and the corresponding position of second tabula rasa.
Aforesaid a kind of multi-layer sheet skin is the wiring board of the asymmetric tabula rasa of pressing again, it is characterized in that: be provided with the PP dielectric layer between the described multi-layer sheet and first tabula rasa, second tabula rasa.
Aforesaid a kind of multi-layer sheet skin is the wiring board of the asymmetric tabula rasa of pressing again, it is characterized in that: on described multi-layer sheet, also be provided with second area, described second area is provided with welding resisting layer.
Aforesaid a kind of multi-layer sheet skin pressing is not more claimed to it is characterized in that the wiring board of tabula rasa: on described multi-layer sheet, first tabula rasa and second tabula rasa, have and make head of screw and the conplane counter sink of wiring board.
The utility model compared with prior art has following advantage:
The utility model is employed in multi-layer sheet, first tabula rasa, the corresponding position of second tabula rasa and is provided with rivet hole; Through rivet multi-layer sheet, first tabula rasa, second tabula rasa are carried out pressing after fixing again; The slip of interlayer in the time of effectively preventing pressing; And what use at interlayer is gummosis PP dielectric layer not, PP dielectric layer gummosis in the time of can effectively reducing pressing and the problem of the wiring board quality that produces.

[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated:
A kind of multi-layer sheet skin is the wiring board of the asymmetric tabula rasa of pressing again; Include multi-layer sheet 1; Be respectively equipped with first area A on the two sides of described multi-layer sheet 1; On the first area A on multi-layer sheet 1 positive and negative two sides, be correspondingly provided with first tabula rasa 2, second tabula rasa 3, the material of described first tabula rasa 2, second tabula rasa 3 is the FR-4 tabula rasa, is provided with rivet hole 4 in described multi-layer sheet 1, first tabula rasa 2 and second tabula rasa, 3 corresponding positions.Pass rivet hole 4 with rivet, with multi-layer sheet 1, first tabula rasa 2 and second tabula rasa, 3 fixed positions, interformational sliding when avoiding pressing.
Be provided with the PP dielectric layer between the described multi-layer sheet 1 and first tabula rasa 2, second tabula rasa 3, the PP dielectric layer that this PP dielectric layer is a not gummosis, PP dielectric layer gummosis not after the pressing, the quality problem that causes because of PP dielectric layer gummosis when effectively reducing pressing.
On described multi-layer sheet 1, also be provided with second area B, described second area B is provided with welding resisting layer.This welding resisting layer is a kind of oily liquids, but the circuit on the permanent protection printed substrate prevents the circuit oxidation or causes open circuit or short circuit problem because of wiping flower because of carelessness.
On described first tabula rasa 2 and second tabula rasa 3, have and make head of screw and the conplane counter sink 5 of wiring board.
