As shown in figure 1, the utility model provides a half tone for electrically conductive silver thick liquid capability test makes the half tone through screen frame and screen cloth, uses electrically conductive silver thick liquid printing film pattern. The net frame is an aluminum alloy frame, and the net cloth is 300-mesh polyester net cloth. The film pattern comprises a first broken line segment 1, a second broken line segment 2, a third broken line segment 3 and a fourth broken line segment 4, wherein the lengths of the first broken line segment 1, the second broken line segment 2, the third broken line segment 3 and the fourth broken line segment 4 are the same and are all 2 meters. The line width ratio of the first fold line segment 1, the second fold line segment 2 and the third fold line segment 3 is 4.
The first broken line segment 1, the second broken line segment 2 and the third broken line segment 3 are vertical broken line segments, and the fourth broken line segment 4 is a transverse broken line segment. The line width of the first broken line segment 1 is 0.4 mm to 0.6 mm. The line width of the second fold line segment 2 is 0.2 mm to 0.3 mm. The line width of the third fold section 3 is 0.1 mm to 0.15 mm.
When the device is used, the line width of the first fold line section 1 is 0.6 mm, the line width of the second fold line section 2 is 0.3 mm, and the line width of the third fold line section 3 is 0.15 mm. The resistances of the first broken line segment 1, the second broken line segment 2 and the third broken line segment 3 are respectively represented as R1, R2 and R3, under ideal conditions, when the first broken line segment 1, the second broken line segment 2 and the third broken line segment 3 are in the same line length, the discrete degree of the resistance of the conductive silver paste and the proportion of the line width is as follows: r1: r2: r3= 1.
Comparing the resistance of the same pattern of the silver paste detection screen plates corresponding to different conductive silver pastes, wherein if the resistance is higher, the resistance performance is worse; the lower the resistance, the better the resistance performance. And secondly, comparing the proportional discrete degree of the resistance and the line width of the same conductive silver paste to track the line width range of the conductive silver paste suitable for printing, wherein the resistance begins to suddenly change under the line width of a plurality of thin lines, and the resistance value exceeds a proportional value. For example, if R2 is greater than 2R1 and R3 is greater than 4R1, the excess is not suitable for the line printing of the current line width.
The conductive silver paste has the characteristics of no line expansion after printing, small film thickness, small consumption (lower mold quantity) and small resistance. The above items are often difficult to satisfy simultaneously due to mutual influence, and in addition, the situations of large consumption and small resistance and the situation of wide line width and small resistance need to be eliminated by measuring the thickness and the line width of the die. Some conductive silver pastes are thinner and thinner along with the line, the resistance can suddenly change over a proportion, and the conductive silver pastes are not suitable for fine line printing. Some conductive silver paste has small resistance and large fine line resistance, and is not suitable for fine lines. Some conductive silver paste may have a slightly larger resistance, but the fine line proportion is good, and the line width does not influence the resistance increase over the proportion. For example, if R2 is close to 2R1 and R3 is larger than 4R1, it indicates that the conductive silver paste is suitable for the wiring of the second fold section 2, and it is not proper if the wiring is used for the third fold section 3. If R3 is equal to or close to 4R1, the conductive silver paste is suitable for line width printing of the third fold line section 3; if R2 exceeds 2R1 and R3 exceeds 4R1, the conductive silver paste is suitable for line width printing of the first broken line segment 1. Ideally, the closer R2 is to 2R1, the better R3 is to 4R1, and the more widely separated (i.e., the more the resistance drift) the less suitable it is for printing fine lines in this range.
According to the resistance of the fourth broken line segment 4 and the second broken line segment 2, the suitable direction of the customer routing printing can be judged, the resistance value of the fourth broken line segment 4 is represented as R4, if R4 is larger than R2, the printing direction is suitable for the vertical printing direction, and if R4 is smaller than R2, the printing direction is suitable for the horizontal printing direction.
By testing the adhesive force, bending and hardness of the first fold line segment 1, the second fold line segment 2 and the third fold line segment 3, the adhesive force, bending and hardness of the same silver paste under different widths are obtained, and the relation between diffusion broadening and adhesive force of conductive silver pastes with different line widths is compared.
The film pattern also includes rectangular blocks 5 and equilateral triangular strings 6. Rectangular block 5 can shine through the light source lamp and observe out bubble, sand eye and levelling nature, can survey the line width through the microscope, and the thick membrane of coarse appearance survey is thick. The resistance measurement of the equal-side triangular string line 6 can judge the trailing degree of the expanded side, the more serious the expanded side is, the more the triangular is expanded, the more the conductive silver paste adhered to the next triangular is, and the resistance is small.
To sum up, the utility model discloses a half tone for electrically conductive silver thick liquid capability test through ingenious design, has designed different film patterns, and the isometric perpendicular broken line section of three different linewidths and a horizontal broken line section make electrically conductive silver thick liquid can select the film pattern of the line width direction that is fit for, and rectangular block and equilateral triangle series line further test the performance of electrically conductive silver thick liquid to a great extent has promoted printing quality, has saved the human cost. Therefore, the utility model effectively overcomes all sorts of shortcomings in the prior art and achieves better practical effect.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
