Abstract
A method for producing a ceramic dielectric antenna with multi-metal sides comprises the following steps that: 1, a ceramic dielectric material is shaped and is fired into a cubic ceramic dielectric body (1); 2, the surface of the ceramic dielectric body (1) is pretreated; 3, a chemical plating method is utilized to form surface metal layers (2) which completely cover six sides; and 4, grinding is carried out, the surface metal layers which are not needed and the metal layers at electrode partition gaps are removed, so electrode sides (21), (22) and (23) are formed, and a final ceramic dielectric antenna product is formed. The chemical plating method is utilized to form the surface metal layers (2) which completely cover the six sides, then grinding is carried out to form electrodes, so metal sides are reliably connected with each other; thousands of ceramic dielectric bodies can be processed simultaneously when the electrodes are formed through the chemical plating, dozens of ceramic dielectric bodies also can be processed simultaneously after being arrayed during the mechanical grinding, so the efficiency is greatly improved; and the mechanical grinding processing precision is high, and the electrical property and consistency of the product can be improved.
Description
Technical field
The present invention relates to a kind of manufacturing approach of cube shaped ceramic medium antenna, a kind of manufacture method that the ceramic medium antenna of a plurality of metal coverings is arranged.
Background technology
Cube shaped ceramic medium antenna is widely used in fields such as GPS, radio frequency identification, bluetooth, mobile communication.For making the ceramic medium antenna miniaturization; Generally be designed to the gps antenna or the Bluetooth antenna (Fig. 1) of surface attaching type; Or the RFID antenna of electric little loop antenna structure (Fig. 2); A main feature of this type antenna is on a plurality of surfaces of ceramic dielectric body, to form metal electrode layer, to realize the performance of antenna.The prior manufacturing method of this type antenna is the surface electrode that forms ceramic medium antenna with the conductive silver paste printing, and a plurality of electrode surfaces need to print several times just to manufacture a product, and its technical process is as shown in Figure 3.This process is owing to relate to the repeatedly printing of a product and silver ink firing repeatedly, so working (machining) efficiency is lower, and metal covering be connected with metal covering unreliable.
Summary of the invention
It is higher that the present invention is intended to propose a kind of working (machining) efficiency, and metal covering is connected the manufacture method of the ceramic medium antenna that a plurality of metal coverings are arranged reliably with metal covering.
This have the manufacture method of the ceramic medium antenna of a plurality of metal coverings may further comprise the steps:
(1) with the medium ceramic material moulding and be fired into cube shaped ceramic dielectric body (also can adopt the large stretch of ceramic dielectric block of moulding and fire, machine cuts becomes the ceramic dielectric body of monolithic then);
(2) ceramic dielectric body is carried out surface preparation;
(3) method of ceramic dielectric body and function chemical plating with (two) step gained forms complete covered surfaces metal level on six faces;
(4) parts with (three) step gained carry out grinding, remove the metal level at unwanted surface metal-layer and dividing electrodes slit place, form surface electrode, become final ceramic medium antenna product.
This manufacture method that the ceramic medium antenna of a plurality of metal coverings is arranged; Owing to adopt chemical plating on six faces, to form complete covered surfaces metal level; Remove unwanted surface metal-layer and form electrode with grinding again, metal covering is reliable with being connected of metal covering; Can process together by several thousand ceramic dielectric bodies when chemical plating forms electrode, efficient improves greatly; When mechanical grinding is got rid of unwanted surface metal-layer, also can tens processing together after the arrangements, efficient obviously improves; The machining accuracy of mechanical grinding is very high, can guarantee that the product electrode rim has excellent precision, helps to improve the consistency level of product processing and the electrical property of product.

Embodiment
Method of the present invention is applicable to cube shaped dielectric antenna production of products such as square, cuboid; Circle and special-shaped antenna be suitable employing method of the present invention then.
As shown in Figure 4, this have the manufacture method of the ceramic medium antenna of a plurality of metal coverings may further comprise the steps:
(1) in figure shown in (A), with the medium ceramic material moulding and be fired into cube shaped ceramic dielectric body 1;
(2) preliminary treatment is carried out on the surface of ceramic dielectric body 1;
(3) shown in (B) among the figure, the method that (two) is gone on foot the ceramic dielectric body and function chemical plating of gained forms complete covered surfaces metal level 2 on six faces;
(4) like (C) among the figure with (D); The parts of gained carry out grinding with (three) step; Remove the metal level at unwanted surface metal-layer (all or part of of certain metal covering) and dividing electrodes slit place, form surface electrode 21,22,23, become final ceramic medium antenna product.
In the manufacture method of this ceramic medium antenna that a plurality of metal coverings are arranged, also can adopt the method for laser ablation to remove the part surface metal level in the step (four), form required surface electrode.When adopting laser ablation to get rid of unwanted metal level, also can tens disposable processing after the arrangement, the machining accuracy of laser ablation is also very high, can obtain the product of the high and good electrical property of consistency level.
In the manufacture method of this ceramic medium antenna that a plurality of metal coverings are arranged, (two) described surface preparation of step can be adopted methods such as mechanical treatment, electrochemical deoiling, firstization of chemistry, sensitization or activation; Main effect be adjustment ceramic dielectric surface roughness, eliminate greasy dirt, improve the ceramic dielectric body surface topography, improve adhesion, the catalytic activity that increases the ceramic dielectric surface to be to guarantee carrying out smoothly of next step chemical plating.The method of the chemical plating described in (three) step can adopt methods such as chemical nickel plating, electroless copper or chemical plating stannum.For example, can adopt nickel chemical plating technology to form metal back layer earlier, and then form surface metal-layer through electrosilvering technology above that.The method of above-mentioned surface preparation and chemical plating is all ripe prior art.
