The utility model discloses a PCB makeup structure for OLED shows screen a little, PCB makeup structure comprises PCB makeup and the technological limit that is equipped with all around of locating the PCB makeup, and wherein the PCB makeup is formed by the concatenation of the same PCB veneer of a plurality of shape size, connects through the V-CUT secant between the adjacent PCB veneer. The utility model provides a PCB makeup structure comprises a plurality of PCB makeup that are array form and arrange the PCB veneer, adds the technology limit around the PCB makeup, satisfies bonding OLED little display screen demand, satisfies PCB board area demand as little as possible, does not influence the PCB board function simultaneously, and lets bonding efficiency increase at double, practices thrift the system board cost to after processing is accomplished, can break off the use with the fingers and thumb by V-CUT secant department during the assembly.
Description
Technical Field
The utility model belongs to the technical field of OLED shows, more specifically, the utility model relates to a PCB makeup structure for OLED shows screen a little.
Background
With the development of OLED micro-displays, the requirement of PCB (Printed Circuit Board) for application is also increasing, but in the process of PCB design, due to the requirement of bonding OLED micro-displays, the PCB Board edge needs to leave a space, which is a process edge, resulting in wasted Board space and low bonding efficiency, as shown in fig. 1.
SUMMERY OF THE UTILITY MODEL
The utility model provides a PCB makeup structure for OLED shows screen a little aims at solving the problem that the panel that current PCB board exists is extravagant, and nation decides inefficiency.
The utility model discloses a realize like this, a PCB makeup structure for OLED shows screen a little, PCB makeup structure is equipped with the technology limit by the PCB makeup and locates all around of PCB makeup and constitutes, and wherein the PCB makeup is formed by the concatenation of the PCB veneer that a plurality of shape size is the same, connects through the V-CUT secant between the adjacent PCB veneer.
Furthermore, the PCB single boards in the PCB jointed board are arranged in an array form.
Further, the width of the technical edge is 5 mm.
The utility model provides a PCB makeup structure comprises a plurality of PCB makeup that are array form and arrange the PCB veneer, adds the technology limit around the PCB makeup, satisfies bonding OLED little display screen demand, satisfies PCB board area demand as little as possible, does not influence the PCB board function simultaneously, and lets bonding efficiency increase at double, practices thrift the system board cost to after processing is accomplished, can break off the use with the fingers and thumb by V-CUT secant department during the assembly.

Fig. 1 is a schematic diagram of a PCB single board structure provided in the prior art;
fig. 2 is a schematic structural view of a PCB jointed board according to an embodiment of the present invention;
1, PCB single board, 2, PCB jointed board, 3, process edge and 4, V-CUT cutting line.
Detailed Description
The following detailed description of the embodiments of the present invention will be provided to help those skilled in the art to more fully, accurately and deeply understand the concept and technical solutions of the present invention, through the description of the embodiments with reference to the accompanying drawings.
Fig. 2 is a schematic diagram of a PCB panel structure for an OLED micro display provided in an embodiment of the present invention, and for convenience of description, only the portions related to the embodiment of the present invention are shown.
The PCB jointed board structure is composed of a PCB jointed board 2 and a technical edge 3 arranged around the PCB jointed board 2, wherein the PCB jointed board 2 is formed by splicing a plurality of PCB single boards 1 with the same shape and size, and the adjacent PCB single boards 1 are connected through a V-CUT CUT line 4.
The V-CUT cutting line 4 in the utility model is a cutting line formed by adopting the V-CUT process, which is convenient for breaking the PCB jointed board 1 off by hands; the PCB veneers 1 in the PCB jointed board 2 are arranged in an array form, for example, the PCB jointed board 2 is formed by arranging the PCB veneers 1 in other ways such as 4 × 3, 4 × 4, 4 × 5, etc.
In the embodiment of the present invention, the width of the technical edge is 5 mm.
The following examples illustrate: will the utility model discloses the implementation provides 2 areas of PCB makeup and current PCB face area carry out comparative analysis.
As shown in fig. 1, the conventional PCB is sized as follows: the length is 26mm, the width is 24mm, and the width of the technical edge is 5 mm;
the area of the single plate is as follows: 26 x 24-624
The actual single plate area used is (26-10) × (24-10) ═ 16 ═ 14 ═ 224
If 120 single boards are needed: 624 × 120 ═ 74880
The PCB jointed board shown in FIG. 2 comprises 12 PCB single boards, the periphery of which is a technical edge, and the technical edge is 5mm wide;
area of 12 jointed boards: (14 × 4+10) (16 × 3+10) ═ 66 × 58 ═ 3828
If 120 single boards are needed: 3828 10 ═ 38280
Average area of PCB single board: 319 (38280/120) ═ 319
Therefore, by adopting the PCB splicing technology of the utility model, the process margin can be saved in a large area, and the production cost can be reduced; in addition, bind regularly to current PCB veneer, once only can bind a PCB veneer, it is right the utility model provides a when the PCB makeup is bound regularly, once throw 12 PCB veneers and bind simultaneously, improve the binding efficiency greatly.
The utility model provides a PCB makeup structure comprises a plurality of PCB makeup that are array form and arrange the PCB veneer, adds the technology limit around the PCB makeup, satisfies bonding OLED little display screen demand, satisfies PCB board area demand as little as possible, does not influence the PCB board function simultaneously, and lets bonding efficiency increase at double, practices thrift the system board cost to after processing is accomplished, can break off the use with the fingers and thumb by V-CUT secant department during the assembly.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
