Description

A kind of flexible PCB and its code spraying method
Technical field
The present invention relates to flexible PCB field more particularly to a kind of flexible PCBs and its code spraying method.
Background technology
Present electronic equipment(Such as mobile phone, tablet computer, television set, intelligent wearable device etc.)Display screen module (Liquid crystal display module, LCM)Production process in need to carry out spray identification code(Such as Quick Response Code), Its production and intermediate links are effectively tracked so that manufacturer and client can be transferred through scanning recognition code.But traditional spray identification Code mode is usually that identification code is sprayed on the screen of LCM, due to there are protective film, when protective film comes off, then being identified on screen Code can be lost.Therefore identification code is lost in order to prevent, and identification code is sprayed on the FPC (flexible PCB) of LCM by manufacturer, due to There are many conducting wires on FPC, cause the surface irregularity of FPC, and FPC is usually black, and coding is dotted injection, because This sprays white code on the FPC of black, in addition the rough structure on FPC surfaces so that and coding is light, coding point easy to be lost, So that the identification code of injection can not be accurately identified by barcode scanning equipment.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention proposes a kind of flexible PCB and its code spraying method, the party Method can be such that the identification code on flexible PCB is easily identified and not easy to lose.
The technical solution adopted by the present invention is to design a kind of flexible PCB, including substrate and is set on the substrate Conducting wire.The bending region that is not required on the flexible PCB is provided with a printing zone.Priming paint is printed in the printing zone, So that the printing zone is an even curface.An identification code is coated in the printing zone.
In addition, the present invention also provides a kind of code spraying methods of flexible PCB, include the following steps:
Step 1:One flexible PCB is provided;
Step 2:The part that bending is not required on the flexible PCB selects a printing zone, and prints a bottom in the printing zone Paint, becomes an even curface by the printing zone;And
Step 3:An identification code is sprayed on the priming paint.
Compared with prior art, the beneficial effects of the invention are as follows:The identification code on flexible PCB can be made easily to be known It is other and not easy to lose.
Description of the drawings
Fig. 1 is the structure diagram for the flexible PCB that first embodiment of the invention provides.
Fig. 2 is the flow chart of the code spraying method for the flexible PCB that second embodiment of the invention provides.
Specific embodiment
Invention is described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, first embodiment of the invention provides a kind of flexible PCB 100, including a substrate 10 and set Conducting wire 20 on the substrate 10.
There is a printing zone 11 on the substrate 10.The printing zone 11 is printed with priming paint, will be concave-convex on the substrate 10 Flat surface does not become an even curface.An identification code 12 is injected in the printing zone 11(Such as Quick Response Code, bar code etc.). The shape of the printing zone 11(Such as square, rectangle or circle etc.)And area is set according to the actual needs of manufacturer It is fixed.The color of the printing zone 11 is different from the color of the substrate 10, and the color of the printing zone 11 and the identification code 12 Color is different.The printing zone 11 uses two kinds of larger colors of aberration, and the printing zone 11 and the identification with the substrate 10 Code 12 is using two kinds of larger colors of aberration so that the identification code 12 is easier identified.In the present embodiment, due to the substrate 10 generally black, therefore use vision maximum drop principle, are designed as pure white, by the identification code by the printing zone 11 12 are designed as black.
It is appreciated that the shape of the printing zone 11 and the shape of the identification code 12 match, if than the identification code 12 For Quick Response Code, then the printing zone 11 is square;If the identification code 12 is bar code, which is rectangle. As long as the area of the printing zone 11 is more than or equal to the shape of the identification code 12.
In the present embodiment, which is arranged on the part that bending is not required on the substrate 10, can prevent from destroying The printing zone 11 and the identification code 12, and manufacturer or client can be facilitated to carry out the scanning work of the identification code 12.
As shown in Fig. 2, a kind of code spraying method for flexible PCB that second embodiment of the invention provides, including following step Suddenly:
S1:One flexible PCB is provided.The flexible PCB includes the conducting wire of a substrate and setting on the substrate.
S2:A printing zone is selected on the flexible PCB, and a priming paint is printed in the printing zone, by the Printing Zone Domain becomes an even curface.In the present embodiment, printing zone setting is not required to the part of bending on the substrate.The printing The shape in region(Such as square, rectangle or circle etc.)And area is set according to the actual needs of manufacturer.Due to Flexible PCB has a conducting wire, therefore surface irregularity, the priming paint recessed place is filled up until with convex place one Sample is high, so as to which the rough surface is become a plane.
S3:An identification code is sprayed on the priming paint(Such as Quick Response Code, bar code etc.).The color of the printing zone and the knowledge The color of other code is different, and using two kinds of larger colors of aberration so that the identification code is easier identified.In the present embodiment In, since the flexible PCB is generally black, vision maximum drop principle is used, which is designed to pure The identification code is designed as black by white.It is appreciated that the shape of the printing zone and the shape of the identification code match, than If the identification code is Quick Response Code, then the printing zone is square;If the identification code is bar code, which is length It is square.As long as the area of the printing zone is more than or equal to the shape of the identification code.
After the completion of coding, in process below, the barcode scanning equipment that may be employed in the market carries out barcode scanning, soft to collect this The circulation relevant information of electronic equipment where property circuit board.
Compared with prior art, flexible PCB and its code spraying method of the present invention, pass through the printing in flexible PCB One identification code of area spray so that the identification code is more easy to identify;Since the identification code is sprayed directly on on the flexible PCB, It is not easy to lose.
Above-described embodiment is merely to illustrate the specific embodiment of the present invention.It should be pointed out that for the general of this field For logical technical staff, without departing from the inventive concept of the premise, several deformations and variation can also be made, these deformations and Variation should all belong to the scope of protection of the present invention.
