Abstract
The utility model relates to a plating structure at a joint part of an FPC (flexible printed circuit) and a plastic shell. The structure comprises a plastic substrate layer, a first metal powder-glue mixing layer, an FPC connecting part with small holes, a second metal powder-glue mixing layer, an acid bright copper-plated layer and a gold-plated layer, wherein the FPC connecting part with the small holes is connected with the first metal powder-glue mixing layer and the second metal powder-glue mixing layer through small holes. The plating structure disclosed by the utility model realizes tightly combining the FPC and the plastic shell, and saves space, so that the plating structure at the joint part of the FPC and the plastic shell has effects of being bright in outline, firm in combining and small in occupied space with the improvement on the two aspects.
Description
Technical field
The utility model belongs to printed-board technology field, relates in particular to a kind of FPC and plastic shell connecting portion coating structure.
Background technology
At present, FPC and the connected mode of plastic casing mostly be use fixed screw by both twist with together with, but this fixed screw not only takies larger space, and along with use time wearing and tearing, screw very easily stripped thread even comes off, after fixed screw comes off, FPC and plastic casing no longer link together, and this will affect the normal use of product, directly affects the service life of product.
As can be seen here, the syndeton of above-mentioned existing FPC and plastic casing still has many defects, and is urgently improved.
Because the defect that the syndeton of above-mentioned existing FPC and plastic casing exists, the design people is based on being engaged in this type of product design manufacture for many years, amass and have abundant practical experience and professional knowledge, actively research and innovation in addition, to founding a kind of FPC and plastic shell connecting portion coating structure, the syndeton that can improve general existing FPC on the market and plastic casing, makes it have more competitiveness.Through constantly research, design, and after repeatedly studying sample and improving, finally create the utility model having practical value.
Utility model content
Technical problem underlying to be solved in the utility model is, overcome the defect of the syndeton existence of existing FPC and plastic casing, and provide a kind of FPC and plastic shell connecting portion coating structure, the syndeton that has overcome existing FPC and plastic casing takes up room greatly, the caducous defect of fixed screw, make its outward appearance light, combination firmly, take up room little, improve the life-span of FPC and plastic shell connecting portion coating structure.
The utility model solves its technical problem underlying and realizes by the following technical solutions.According to a kind of FPC and the plastic shell connecting portion coating structure that the utility model proposes, this structure comprises plastic base bottom from inside to outside successively, the first metal dust-glue mixed layer, narrow meshed FPC connecting portion, the second metal dust-glue mixed layer, acid bright copper plating layer, Gold plated Layer, narrow meshed FPC connecting portion connects the first metal dust-glue mixed layer and the second metal dust-glue mixed layer by aperture, the hole diameter of narrow meshed FPC connecting portion is 0.5 millimeter to 3 millimeters, the thickness of the first metal dust-glue mixed layer is 200 microns to 300 microns, the thickness of the second metal dust-glue mixed layer is 200 microns to 300 microns, the thickness of acid bright copper plating layer is 30 microns to 50 microns, the thickness of Gold plated Layer is 15 microns to 35 microns.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, first narrow meshed FPC connecting portion links together the first metal dust-glue mixed layer and the second metal dust-glue mixed layer by aperture, thereby fix the position of FPC, and the first metal dust-glue mixed layer is attached on plastic base bottom, therefore, FPC also just links together with plastic casing, the various parameters such as the formula of next control electroplate liquid, accurately control the thickness of each coating, effectively save space, and by the method for electroplating surface, make narrow meshed FPC connecting portion and the second metal dust-glue mixed layer, the first metal dust-glue mixed layer forms an entirety, and then realize combining closely of FPC and plastic casing, save space, the improvement of this two aspect makes the utility model FPC and plastic shell connecting portion coating structure have outward appearance light, in conjunction with firm, little effect takes up room.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model feature part, for making professional and technical personnel can better understand technological means of the present utility model, and can be implemented according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be described in detail as follows.
Accompanying drawing explanation
Fig. 1 is the profile of the utility model embodiment.
Description of reference numerals: 1, plastic base bottom; 2, the first metal dust-glue mixed layer; 3, narrow meshed FPC connecting portion; 4, the second metal dust-glue mixed layer; 5, acid bright copper plating layer; 6, Gold plated Layer; 7, aperture.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment, structure, feature and effect thereof according to the utility model proposes, be described in detail as follows.
Refer to shown in Fig. 1, a kind of FPC of the present utility model and plastic shell connecting portion coating structure, this structure comprises plastic base bottom 1 from inside to outside successively, the first metal dust-glue mixed layer 2, narrow meshed FPC connecting portion 3, the second metal dust-glue mixed layer 4, acid bright copper plating layer 5, Gold plated Layer 6, narrow meshed FPC connecting portion 3 connects the first metal dust-glue mixed layer 2 and the second metal dust-glue mixed layer 4 by aperture 7, aperture 7 diameters of narrow meshed FPC connecting portion 3 are 0.5 millimeter to 3 millimeters, the thickness of the first metal dust-glue mixed layer 2 is 200 microns to 300 microns, the thickness of the second metal dust-glue mixed layer 4 is 200 microns to 300 microns, the thickness of acid bright copper plating 5 is 30 microns to 50 microns, the thickness of Gold plated Layer 6 is 15 microns to 35 microns.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong to the scope of technical solutions of the utility model.
