Brief description of the drawings
Shown in Fig. 1 is the schematic diagram of casting technique;
Shown in Fig. 2 is the structural representation of the utility model reality;
Shown in Fig. 3 is the explosive view of the utility model structure.
Embodiment
Below with reference to accompanying drawing of the present utility model; technical scheme in the utility model embodiment is carried out to clear, complete description and discussion; obviously; as described herein is only a part of example of the present utility model; it is not whole examples; based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, belongs to protection range of the present utility model.
The utility model is realized stack and the common sintering of multilayer material, and the laminating method of curtain coating green compact is a lot, mainly comprises: pressure sintering lamination and improved technique thereof, bonding base stack technology and solvent-based stack technology etc.Different stack technologies has its unique feature, because the flow casting molding of base sheet is mainly divided into traditional organic group and water base two kinds, the additive adopting in its forming process and the additive difference that affects on base piece performance will produce different laminated process in lamination process.Therefore, can select according to specific circumstances.But method is not limited to above-mentioned several method.
For the ease of the understanding to the utility model embodiment, be further explained as an example of specific embodiment example below in conjunction with accompanying drawing, and each embodiment does not form the restriction to the utility model embodiment.
In the present embodiment, can adopt casting technique.Please refer to Fig. 1, casting technique is a kind of forming method of ceramic, first the powder crushing and organic plasticiser solution are mixed and made into the slip 11 with certain viscosity by suitable proportioning, slip flows down from container, scraped and be coated in special base band 13 with certain thickness by scraper 12, please refer to shown in accompanying drawing one, base band 13 use rollers 14 drive.Drying, peel the film that becomes green compact band from above after solidifying, then need to do the processing such as die-cut, laminated to green compact band according to the size and dimension of finished product and process, make blank finished product to be sintered.And then through degreasing sintered, color treatments, the production processes such as polishing and machine work have just been made ceramic product.
A laminated construction for electronic product ceramic shell, comprising: ceramic layer 1; One or more layers toughness material layer, is superimposed upon a side of ceramic layer 1; Antenna radiator layer 2, is superimposed upon on one or more layers toughness material layer; Ceramic layer, one or more layers toughness material layer and antenna radiator layer 2 are by sintering, hot pressing or bonding mode combination.So, the demand of the satisfied outward appearance of outer field ceramic material, and the effect of the overfill protection ceramic layer that the toughness material layer of internal layer plays and then improved the resistance to drop performance of ceramic product.
Antenna radiator layer is generally metallic conductor, is superimposed upon on one or more layers toughness material layer by silk-screen or other technologies.Antenna radiator layer 2 is metallic conductors of given shape and layout, is then pruned and be total to by shape to burn to form required pattern; Or,, by radium-shine processing procedure, unwanted region is ablated off to the required form that obtains and the pattern of layout, in curtain coating lamination process, do not need like this metal level to make specific shape, only need whole and do metal level, and pattern is formed by follow-up processing procedure.
Antenna product is used for receiving and transmitting, and its core is radiant body, normally has the metallic conductor of given shape and layout, and we are referred to as pattern (pattern).After curtain coating ceramic green, we can be adhered to the metal material of given shape to be superimposed upon on ceramic green by silk-screen technology or additive method, and then prune and be total to burning by shape.As shown in Figures 2 and 3.Ceramic product and antenna have been realized integration, have greatly saved size and the space of product.
In order to promote the performance of antenna, also comprise one or more layers auxiliary material, be superimposed upon both sides or a side of antenna radiator layer, in order to promote or to improve the performance of antenna radiator layer, for example, according to the material that need to add differing dielectric constant and loss of concrete antenna.
Antenna radiator layer can also be can active material, by radium-shine processing procedure by the surface activation of antenna radiator layer, make it have platability, then by electroplating or change depositing process and form the pattern of required form and layout, shape and layout that can be as shown in Figures 2 and 3.
By curtain coating lamination, we can be combined in the material of some specific purposes on ceramic shell, for example, the object of heat radiation or EMI(Electro-Magnetic Interference, electromagnetic interference) object etc.As graphite, Ferrite Material etc.
Although the individual layer curtain coating of traditional ceramics can realize a variety of colors, the color of single product itself is single.By the technique of multilayer curtain coating, and the firing of later stage.In the utility model, can realize sample look and various shapes on single product.
The formation method of the laminated construction of above-mentioned electronic product ceramic shell specifically comprises the following steps:
S1, prepare ceramic layer, one or more layers toughness material layer;
S2, by stacked one or more layers toughness material ceramic layer one side that is added in;
S3, be added on one or more layers toughness material layer stacked antenna radiator;
S4, by sintering, hot pressing or bonding mode by ceramic layer, one or more layers toughness material layer and the combination of antenna radiator layer.Toughness material layer can be selected its number of plies according to the actual requirements, certainly, also not necessarily needs toughness material layer.In the situation that there is no toughness material layer, antenna radiator layer is directly superimposed upon on ceramic layer.
Between S3 and S4, also comprise: in the both sides of antenna radiator layer or superpose one or more layers auxiliary material of a side, in order to promote or to improve the performance of antenna radiator layer.
The utility model is applicable to casting technique, but is not limited only to casting technique.Stromatolithic structure extends to ceramic injection molding process, and the dijection in similar plastic-injection technique or the way of encapsulate realize the stack between can injected plastics material not of the same race by Shooting Technique.
The above; it is only preferably embodiment of the utility model; but protection range of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
