Description

A kind of method of accurate making lamination element

Technical field

The present invention relates to a kind of method of accurate making lamination element.

Background technology

Now, the inductance value of the inductance element of making through ceramic green band lamination has bigger deviation with design load.To this, the common way of industry is: the ratio design load of making the inductance value of inductance element is big, reduces the inductance of inductance element through increasing via layer then, thereby reaches near design load.Its manufacturing process can be referring to shown in Figure 2.

Handle like this, although can produce the lamination element that meets certain required precision in the larger context; But, in the process of trial-production, must design the parameter of via layer again; And in original lamination element increase via layer, complex process, efficient are very low; And be difficult to accurately near design load, can waste a lot of ceramic green bands simultaneously as via layer; The loop length of inductance increases, and spent metal material increases.In addition, when the ratio design load that the inductance value of inductance element is done is little, then can not adjust inductance value, thereby cause the waste of inductance element through such scheme.

At present, more and more can not satisfy the requirement on the efficient for increasingly high, the traditional trial-production method that requires that can large batch ofly fast produce high accuracy lamination element.

Summary of the invention

Technical problem to be solved by this invention be propose one can be easy, efficient and the method for manufacturing experimently out the lamination elements such as inductance that meet schedule requirement accurately so that template corresponding is provided for extensive high-precision making lamination element.

To this, the present invention provides a kind of method of accurate making lamination element, comprising:

Dielectric layer making step: make at least two types dielectric layer with electrical appliance part;

Pre-fabricated step: dissimilar said dielectric layers is arranged in sequence, made the lamination element;

Measuring process: measure this lamination element and obtain measured value, this measured value is compared with preset standard value, if the deviation of this measured value and said standard value is then made the lamination element and finished in the scope of setting; Otherwise,

Set-up procedure: adjust the order of said dielectric layer, make another lamination element, carry out said measuring process then.

The different arrangement will cause the change such as the relation between the electric part on the dielectric layer between the different dielectric layers, and then can obtain different from different opering characteristics of electric apparatus such as impedance, inductance value.Adopt technique scheme,, just can change the characteristic electron such as electronic components such as inductance value of the lamination element of trial-production, with the lamination element that obtains to conform to predefined standard value through changing the Rankine-Hugoniot relations between the dissimilar dielectric layers.Compared with prior art, the advantage of technique scheme comprises, does not need to design again the parameter of via layer, also need on original lamination element, not increase via layer, and technology is simple, and efficient is higher.

Preferably, said dielectric layer adopts the ceramic green band.

Further, said electrical appliance part comprises: adopt mode of printing to invest the internal electrode on the said ceramic green band.

Preferably, the number of types of different said dielectric layers is not less than 3.

Further in the preference, in the said pre-fabricated step, the maximum dielectric layer of thickness is in centre position; The closer to the dielectric layer of the maximum dielectric layer of this thickness, its thickness is also big more.

In another further preference, in the said pre-fabricated step, the minimum dielectric layer of thickness is in centre position; The closer to the dielectric layer of the minimum dielectric layer of this thickness, its thickness is also more little.

Below in conjunction with accompanying drawing, more excellent embodiment of the present invention is done further detailed description:

As shown in Figure 2, specify as follows:

Step 100: earlier with the dielectric layer that has electrical layer of the different-thickness more than at least two electronics lamination element that is made;

Step 101: measure the inductance value or the resistance value of this electronics lamination element then,

Step 102: if the deviation of inductance value or resistance value and design load is outside setting range, then

Step 103: the laminated layer sequence of adjustment dielectric layer, carry out said step 100;

Until the deviation of the inductance value of the electronics lamination element of making and design load within setting range.

In conjunction with Fig. 3, the principle of embodiment shown in Figure 2 is described.

The thickness difference of dielectric layer can cause the inductance value of electronics lamination element or the variation of resistance value between the electrical layer.

Fig. 3 is the sketch map that the order of the dieelctric sheet of two different-thickness is adjusted.Wherein, P1: first electrical layer; D1: first dielectric layer; H1: first through hole; H1: the thickness of the first dielectric layer D1; P2: second electrical layer; D2: second dielectric layer; H2: second through hole; H2: the thickness of the first dielectric layer D2.

Like Fig. 4, Fig. 5, shown in Figure 6; Can adopt the relevant position of the method for laser drilling or mechanical punching in ceramic layer 322,332 and 342; Break into through hole 322,332 and 342 respectively; Print internal electrode 311,321,331 and 341 respectively at ceramic layer 312,322,332 and 342, thereby form corresponding ceramic green band 310,320,330 and 340.As shown in Figure 3; The ceramic green band carries out lamination according to following laminated layer sequence: ceramic green band 330,320,340,320,340 and 310; Make corresponding internal electrode 331,321,341,321,341 and 311 be electrically connected successively; Add outer electrode at ceramic green band 330 again, ceramic green band 310 adds outer electrode, thereby forms laminate electronic components.

Be the embodiment that the ceramic green band of two kinds of thickness of a multilayer carries out lamination.This debugs to the specification error scope for small lot, thereby confirms the laminated layer sequence of laminate electronic components, carries out the production of large batch of laminate electronic components again according to this laminated layer sequence.

The specification error scope is a preset definite value, for example 5%.In this embodiment, 12 layer thicknesses are the ceramic layer d1 that is printed with internal electrode P1 of h1, and 8 layer thicknesses are the ceramic layer d2 that is printed with internal electrode P2 of h2, h1＜h2.The inductance value design centre value of product is 68nH, and the ceramic green band has all been held the hole successfully and has been completed for printing.

Referring to method shown in Figure 2, the step that this embodiment is corresponding is:

Step 100; Laminating step; Press the laminated layer sequence lamination of d1, d1, d1, d1, d1, d1, d1, d1, d1, d1, d1, d1, d2, d2, d2, d2, d2, d2, d2, d2 successively, product is being made into laminate electronic components through after a series of making flow process;

Step 101, measuring process is tested the inductance value of this laminate electronic components 300, and central value is 66nH;

Step 102, the deviation of judging measured value and set point are in the setting range step, through judging that this inductance value is worth little by 2.9% than the design centre, within the scope of specification error scope 5%;

Step 103, the adjustment laminating step for improving the inductance value of product, is pressed the laminated layer sequence multi-layered ceramic of d1, d1, d1, d1, d1, d1, d1, d1, d1, d1, d1, d1, d2, d2, d2, d2, d2, d2d2, d2 and is given birth to band;

Execution in step 101, step 101 successively again, the test inductance value central value that obtains product is 68.2nH;
