The invention will be further described below in conjunction with accompanying drawing embodiment:
Fig. 1 is the slave board step synoptic diagram of the embodiment of the invention one;
Fig. 2 is the cutting step synoptic diagram of the embodiment of the invention one;
Fig. 3 is the inductor preparation process synoptic diagram of the embodiment of the invention one;

Embodiment
As shown in Figures 1 to 4, a signal than complete process flow and products thereof of the present invention.
The capacitance type touch control screen production technology of composite base plate, Fig. 1 is the signal of its slave board step, in this step, provides a composite base plate 10, and the upper strata 11 of this composite base plate is PMMA, and lower floor 12 is PC; The area of common this composite base plate is larger, and it is of a size of the several times of individual equipment final products size and even more than the decades of times.In this slave board step, this composite base plate 10 is carried out bulk treatment, adopt the mode of printing the printing ink 20 of shading to be attached to lower floor 12 surfaces of this composite base plate.
Finished after the slave board step, namely entered cutting step, as shown in Figure 2.This step cuts this composite base plate 10 by the processing of CNC equipment, makes it according to the form fractionation of single product, namely obtains required size; Each unit has upper strata 11, lower floor 12 and the printing ink 20 of same form.So, finish of present embodiment product and mounted part.
Such as Fig. 3, be the synoptic diagram of present embodiment sensor preparation process.This step process another of present embodiment mount part: at first prepare an ito thin film 30, these ito thin film 30 molded good touch-control conductive patterns at ito thin film 30 its surperficial applying flexible PCBs 40, interfix the two and electrical communication, obtain sensor.The parts that flexible PCB 40 connects as its corresponding control circuit of the touch-control conductive pattern on the ito thin film 30 with the ito thin film 30 common major parts that form sensor, can be referred to as semi-manufacture FOG.
As shown in Figure 4, the applying step of the embodiment of the invention: step is fitted the part that mounts of above-mentioned two separating treatment, the sensor that will soon have become semi-manufacture FOG among Fig. 3 fits in the lower floor surface of composite base plate 10 among Fig. 2 with optical cement 50, can obtain the finished product of present embodiment, the one side that sensor and this flexible PCB 40 are fitted fits with lower floor 12 surfaces of this composite base plate 10.As shown in the figure, this finished product level from top to down comprises: composite base plate 10, and its upper strata 11 is PMMA, lower floor 12 is PC; Printing ink 20 is positioned at lower floor 12 surfaces of this composite base plate 10; And, sensor, the lower floor that is positioned at this composite base plate 10 is surperficial; Comprise with the ito thin film 30 of touch-control conductive pattern and the fixing and flexible PCB 40 that is communicated with it; Wherein, has optical cement 50 between lower floor 12 surfaces of this composite base plate 10 and this sensor layer.
Scheme from present embodiment, the obvious characteristics of the technical program: this composite base plate 10 and ito thin film 30 are the capacitance type touch control screen of main body, and its structure is very simple, owing to avoided the GF structure of traditional glass substrate, so often can use CNC equipment directly to process, yield is higher; The upper strata 11PMMA of composite base plate 10, skin hardness can be accomplished 6H, intensity is the same with strength of glass, but quality is lighter, is more suitable for the hand-held digital products characteristics, and its crash resistance can be fine, and thickness is thinner.Simultaneously, the technique of the technical program is two processing that mount part with separation of products, only uses an attaching process namely to finish whole touch screen, so production cost and binding yield are greatly improved.
It can also be seen that some other advantage from some improvement projects of present embodiment: as shown in Figure 2, in cutting step, composite base plate 10 outer rims that cut are carried out chamfered, according to product needed, no matter be C angle or R angle, for the chamfered yield of PMMA and the PC material height than glass material.
On the other hand, the technical program can be carried out on 11 surfaces, upper strata of composite base plate 10 the 3D pattern and be processed, utilize the techniques such as wire drawing, transfer technique, colouring to make it to have the structure of 3D solid, wire drawing or polychrome, so surface treatment is difficult to realize in as the scheme of substrate at the practical glass of traditional GF structure.
The above, only for preferred embodiment of the present invention, so can not limit according to this scope of the invention process, the equivalence of namely doing according to claim of the present invention and description changes and modifies, and all should still belong in the scope that the present invention contains.
