Abstract
The utility model relates to an electric appliance key-press plate which includes a substrate plate. The substrate plate is etched with lines and is provided with an insulating layer on the surface. The insulating layer is coated with a protective layer. The protectively layer is pasted with a key-press panel. The electric appliance key-press plate etches lines on a copper material with the PI being the substrate, takes the photosensitive solder resist ink as the insulating layer, and uses the nickel plated alloy coating to protect the bare lines, and at the end pastes the key-press panel, so the process is simplified, the production efficiency is high, the manufacturing cost is reduced, and the product performance becomes superior.
Description
Technical field
The utility model relates to electron trade, especially a kind of electrical equipment keypad.
Background technology
Fast development along with electron trade; The control key device is fast-developing towards the direction of " short; little, light, thin "; And at present with the most usely in the electron trade be the compound mode of thin film circuit (PET material)+key panel: be to use PET to add to cover carbon oil and guarantee to point wear-resisting and print additional dielectric ink, stick on key panel at last to protect exposed circuit as the thick-film printed circuit of ground.But because of the characteristic issues of PET material itself, this material non-refractory, rub resistance not is so product stability is poor.
The utility model content
The technical problem that the utility model will solve is: a kind of process simplification is provided, and production efficiency is high, the electrical equipment keypad that production cost is low.
The utility model solves the technical scheme that its technical problem adopted: a kind of electrical equipment keypad; Comprise the ground plate, be etched with circuit on the described ground plate, the surface of ground plate is provided with insulating barrier; Add on the described insulating barrier and be coated with protective layer, mount key panel on the protective layer.
Specifically, the described insulating barrier of the utility model is the photosensitive solder resist ink lay, and protective layer is the plating nickel-gold layer.
Simultaneously, the production method of the utility model is:
1) use PI to be etched into circuit as the copper material of ground;
2) on the ground plate, print additional photosensitive solder resist printing ink as insulating barrier;
3) on insulating barrier, add the plating nickel-gold layer;
4) mount key panel.
The beneficial effect of the utility model is: 1, flow process is simple, and is more a lot of than other similar products process simplifications; 2, operating efficiency is higher; Because of other similar products need have coating processes, this operation needs personnel's manual alignment, and operating efficiency is not high; And the utility model adopted is that automatic screen printer carries out the photosensitive solder resist printing, and operating efficiency is high; 3, production cost is low; Because of the utility model adopts photosensitive solder resist, be the PI coverlay and other similar products adopt, so just cheap much on the material cost; And also need increase " open material; numerical control, mould is die-cut, compacting; baking " these a series of flow processs during with the production of coverlay, production cost is also exceeded much than the product of consonance design; 4, because of the same Copper Foil that adopts the PI ground, so aspect of performance is superior equally.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the preferred embodiment of the utility model;
Fig. 2 is the structural representation at the keypad back side of the utility model;
Fig. 3 is the positive structural representation of keypad of the utility model;
Among the figure: 1, ground plate; 2, insulating barrier; 3, protective layer; 4, key panel.
Embodiment
Combine accompanying drawing and preferred embodiment that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of electrical equipment keypad as shown in Figure 1 comprises ground plate 1, is etched with circuit on the described ground plate, and the surface of ground plate is provided with insulating barrier 2, adds on the described insulating barrier to be coated with protective layer 3, mounts key panel 4 on the protective layer.
The described electrical equipment keypad employing of the utility model PI is that the copper material of ground is etched into circuit, prints additional photosensitive solder resist printing ink as insulating barrier, adds the exposed circuit of plating nickel-gold layer protection then, mounts the production method of key panel at last.Electrical equipment keypad after processing as shown in Figures 2 and 3.
The just embodiment of describing in the above specification of the utility model; The various fleshes and bloods that illustrate not the utility model constitute restriction; Under the those of ordinary skill of technical field after having read specification can to before described embodiment make an amendment or be out of shape, and do not deviate from the essence and the scope of utility model.
Claims (3)
