Abstract
The utility model relates to a non-uniform-thickness material rivet for a multilayer printed wiring board. The thickness at different positions of the material of the rivet varies. The rivet consists of two parts: a rivet cap and a rivet body. The rivet body consists of two sections of parts which are different in terms of material thickness, one section is thicker, and the other section is thinner. The outer diameters of the rivet body formed by the two sections with different material thicknesses are approximately the same, and the thicker section of the rivet body is connected to the rivet cap. The length of the thicker section of the rivet body is approximately the same as the thickness of an object which needs riveting. Compared with a traditional rivet, the non-uniform-thickness material rivet adopts a partially thickened rivet body so as to enhance the strength of the rivet. Therefore, bending or deformation is not prone to occur during the riveting and locating process. By the adoption of the non-uniform-thickness material rivet, higher yield can be obtained for production of high-grade printed wiring boards.
Description
Technical field
Multilayer printed wiring board need carry out preposition to many central layers before pressing, the printed wiring board after the completion preposition can be sent press to and carry out the pressing processing, thereby is bonded into the printed wiring board of a multilayer.So preposition is a very important treatment step before the printed wiring board pressing.Preposition can adopt heat fused, riveted, pin location, and the rivet location is a kind of very important orientation type.
Background technique
Traditional pressing rivet is to adopt copper product, and material itself is thinner, and rivet itself is yielding crooked and cause the location of printed wiring board deviation to occur in the riveted process, and this deviation can cause printed wiring board to scrap generation.In order to change this drawback, so proposed content of the present invention.
Summary of the invention
The technical problem that the present invention solves is: a kind of non-equal thick material rivet is provided, and after the part was strengthened, rivet just can not be out of shape during riveted through the rivet body, and the Location accuracy of riveted can improve greatly.The rivet of this nesting type is very helpful for the high high-end printed wiring board production of required precision.
Technological scheme of the present invention is: a kind of non-equal thick material rivet is provided, and the material thickness of rivet diverse location is inequality.
Further technological scheme of the present invention is: a kind of non-equal thick material rivet is provided, and described rivet is made up of two parts: rivet cap and rivet body, and wherein the rivet body is made up of two sections different parts of material thickness, and one section is thicker, and one section is thinner.
Further technological scheme of the present invention is: the rivet body in the described non-equal thick material rivet, the outer diameter of the two part rivet bodies that material thickness is different is close.
Further technological scheme of the present invention is: the rivet body in the described non-equal thick material rivet, one section thicker rivet body links to each other with the rivet cap.
Further technological scheme of the present invention is: the rivet body in the described non-equal thick material rivet, the material thickness of thicker one section rivet body is between 0.10～2.0mm.
Further technological scheme of the present invention is: the rivet body in the described non-equal thick material rivet, the material thickness of thin one section rivet body is between 0.05～0.20mm.
Further technological scheme of the present invention is: the rivet body in the described non-equal thick material rivet, the different rivets of two sections material thicknesses constitute as commaterial and are connected to an integral body.
Further technological scheme of the present invention is: the rivet body in the described non-equal thick material rivet, the length of one section rivet body that material approaches is between 0.5～2.0mm.
Further technological scheme of the present invention is: the rivet body in the described non-equal thick material rivet, and the outer diameter of the two part rivet bodies that material thickness is different is close, and the diameter of two part rivet bodies differs scope at ± 50 microns.
Further technological scheme of the present invention is: the rivet body in the described non-equal thick material rivet, the length of the rivet body that material is thicker a section is close with the thickness of the object that needs riveted.
The effect that the present invention obtains is: the rivet body of thickening is strengthened under the effect of rivet value in the part; Rivet is difficult for causing shaft of rivet distortion because of the strength of riveted and becomes crooked when riveted; This can improve the aligning accuracy behind the riveted, thereby improves the production yield of printed wiring board.

Fig. 3 is the side cross-sectional schematic behind " non-equal thick material rivet " and the object riveted.
Embodiment
Below in conjunction with the practical implementation example, technological scheme of the present invention is further specified.
Embodiment of the present invention is: a kind of non-equal thick material rivet is provided; The material thickness of its rivet diverse location is inequality; Described rivet is made up of two parts: rivet cap (shown in 1 among Fig. 1) and rivet body; Wherein the rivet body is made up of two sections different parts of material thickness, and one section thicker (shown in 2 among Fig. 1), one section approaches (shown in 3 among Fig. 1).
The outer diameter of the two part rivet bodies that material thickness is different is close; The diameter of two part rivet bodies differs scope at ± 50 microns; One section rivet body that material is thicker links to each other with the rivet cap; The material thickness of thicker one section rivet body is between 0.10～2.0mm; The material thickness of thin one section rivet body is between 0.05～0.20mm, and the length (shown in a among Fig. 1) of one section thin rivet body is between 0.5～2.0mm for material, and two sections different rivets of material thickness constitute as commaterial and are connected to an integral body.The length of the rivet body that material is thicker a section is close with the thickness of the object that needs riveted; And the rivet body of thin that section of material; In the riveted process, meeting rived also bending and formed the shape riveted body (shown in 3 among Fig. 3) of blooming, thus the purpose that realization is riveted tightly.
Generally, (shown in 4 among Fig. 3) is thick more for the object of required riveted, and used rivet is also just long more, and long more rivet is easy deformation more just.So when the length of rivet body was long more, the material thickness of the rivet body that material is thicker a section also need be selected for use thicker, could strengthen the intensity of rivet so better, makes the riveted Positioning Precision Control in desirable scope.
For more convenient understanding design proposal of the present invention, provided schematic perspective view shown in Figure 2.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
