Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Consult Fig. 2,3,4, one preferred embodiment of the substrate 2 of the utility model tool wire, it is the substrate 2 of an illuminated keyboard, the keyboard of a for example notebook computer of this illuminated keyboard or a desktop computer, this illuminated keyboard is except comprising this substrate 2 of the utility model, also comprise the luminescence unit 3 that a keyboard body (not shown), that is positioned at these substrate 2 tops and has several buttons is installed on this substrate 2 and has the illuminating part 31 at several intervals, and a light guide plate 4 between this substrate 2 and this keyboard body.Wherein, each illuminating part 31 of this luminescence unit 3 is a light-emitting diode (LED), and each illuminating part 31 has an exiting surface 311 that is positioned at side.This light guide plate 4 has one can be towards the light incident sides 41 of the exiting surface 311 of these illuminating parts 31 after stacked with this substrate 2.And the substrate 2 of the tool wire of the present embodiment comprises: the base material 21 of a plastic cement system, a printed circuit cable layer 22 being positioned on this base material 21, and an electroplated lead layer 23 being positioned on this printed circuit cable layer 22.
The base material 21 of the present embodiment is to be made up of lighttight flexible plastic material, and has one and towards the reflecting surface 211 of this light guide plate 4, this reflecting surface 211 can up reflect light upward.This base material 21 also has several prominent granular optically focused sites 212, and these optically focused sites 212, corresponding to these several key positions of this keyboard body, can make light concentrate towards these several buttons and penetrate.
This printed circuit cable layer 22 can utilize the mode of printing such as screen painting or ink jet printing to be formed on the reflecting surface 211 of this base material 21.The function of this printed circuit cable layer 22 is to provide a conductive region, using the making region as follow-up this electroplated lead layer 23.The material of this printed circuit cable layer 22 is conducting polymer composite, for example silver slurry, or other is doped with the electrocondution slurry of conductive metallic material and tool viscosity.Generally speaking the conductive paste composition that, is used to form this printed circuit cable layer 22 comprises organic solvent, inorganic conductive particulate, adhesive and other additives.Wherein, the content of this inorganic conductive particulate is used for determining the conductivity of this electrocondution slurry, the conductive materials such as its material for example silver, copper, gold, or can be the mixing of multiple electric conducting material.This adhesive makes this electrocondution slurry have certain viscosity, and makes this electrocondution slurry after wire mark or spray printing solidify, and makes inorganic conductive particulate each other, and forms stable combination between inorganic conductive particulate and this base material 21.The content number of this organic solvent affects viscosity and the electrocondution slurry rate of drying of this electrocondution slurry.
This electroplated lead layer 23 is also positioned on the reflecting surface 211 of this base material 21, is specifically positioned at the surface of this printed circuit cable layer 22, and utilizes plating mode to be formed on this printed circuit cable layer 22.This electroplated lead layer 23, for patterning designs, is actually by (not shown) that several fine wires form, to be made into the circuit lead for being electrically connected these illuminating parts 31.This electroplated lead layer 23 can be electrically connected the circuit board that a figure does not show, can connect input for driving the control signal of these illuminating parts 31.The material of this electroplated lead layer 23 is metal, for example copper or silver.
Therefore,, when the utility model uses as the substrate 2 of illuminated keyboard, in assembling, on this electroplated lead layer 23, make illuminating part 31 these electroplated lead layers 23 of electrical connection by cemented these illuminating parts 31 of this luminescence unit 3.Again this light guide plate 4 is stacked and placed on the reflecting surface 211 of this substrate 2.When these illuminating parts 31 are luminous, light can enter this light guide plate 4 inside from the light incident sides of this light guide plate 4 41, and be uniformly distributed along the bearing of trend of this light guide plate 4, and up with down appear, the reflecting surface 211 that light down can be subject to this base material 21 up reflects and enters once again in this light guide plate 4.Finally, light mainly appears upward, so that these several keyboards of this keyboard body are luminous around.How to be subject to the effects such as related elements guiding in this illuminated keyboard, reflection, refraction due to light, non-the utility model improvement emphasis, no longer illustrates at this.
In sum, by these reflecting surface 211 reflection rays, and can arrange for this printed circuit cable layer 22; Because this base material 21 is made for nonconducting plastic cement, therefore the utility model provides a conductive region by this printed circuit cable layer 22 is set, and makes follow-uply can form this electroplated lead layer 23 by the electrochemical action of plating mode.And the main material of this electroplated lead layer 23 is metal, compared to this printed circuit cable layer 22 being formed by electric conducting material and other additives, there is better conductivity, therefore with these electroplated lead layer 23 these illuminating parts 31 of electrical connection, can obtain preferably signal conducting effect, make these illuminating parts 31 more sensitive, accurate on controlling.In addition, because this printed circuit cable layer 22 is all lower with the technological temperature of this electroplated lead layer 23, is more than several Baidu compared with general technique for vacuum coating temperature, the utility model is with wire mark and plating mode film forming, this base material 21 of the plastic cement system of being applicable to, can reduce the damage of this base material 21.
Should be noted that to be, this substrate 2 of the utility model must not be confined to the application of illuminated keyboard, but can be applied on the product of the various substrates need to wire.For example, the substrate of known contact panel, comprises a surface and has the base material of the light-permeable of electrode conventionally.Therefore, base material 21 of the present utility model can be also the base material 21 of a light-permeable, when this printed circuit cable layer 22 is set with this electroplated lead layer 23 on this base material 21 of light-permeable, the conductivity of this substrate 2 that this entirety forms is good, signal transmission effect is good, substrate 2 using this as contact panel, contributes to promote touching signals conducting effect and touch-control sensitivity.
Only above-described content, it is only preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented with this, be that all simple equivalences of doing according to the utility model claim and utility model description change and modify, all still belong in the scope that the utility model patent contains.
