Tissue area 103, thereby, can avoid the longitude and latitude tissue 101 of screen cloth 10 or macromolecule residual effect ink bleed attached to it uniform
Degree, thus promote precision and the quality of printed patterns.
According to above-mentioned manufacture method, this utility model provides the half tone pattern of the electronic circuit demand now that may conform to.
Fig. 5 is an embodiment of the present utility model, the upper schematic diagram of half tone pattern.As it is shown in figure 5, it is of the present utility model
(1') half tone pattern 1, comprises: screen cloth and macromolecule layer 11 (11'), and macromolecule layer (11') has the logical of corresponding printed patterns
Hole 111 (111').Fig. 4 A and Fig. 4 B is I in Fig. 51-I1'Section cross-sectional schematic.
Referring to Fig. 4 A and Fig. 4 B, macromolecule layer 11 again, 11' is formed on screen cloth 10, and screen cloth 10 has longitude and latitude tissue
101, first without longitude and latitude tissue area 102 and second without longitude and latitude tissue area 103, wherein second connect height without longitude and latitude tissue area 101
Molecular layer 11, the through hole 111,111' of 11', second without the width w3 of longitude and latitude tissue area 103 more than first without longitude and latitude tissue area 102
Width w2.For through hole 111, the integrity of 111' sidewall and supportive, it is perpendicular to half tone 1, on the cross section on 1' surface, second
The width w3 of tissue area without longitude and latitude 103 is less than through hole 111, and the width w1 of 111', it is also preferred that the left second without longitude and latitude tissue area 103
The width w1 of width w3 and through hole 111,111' flushes.

Containing warp 201a and parallel 201b.Macromolecule layer 21 has the through hole 211,212,213 of corresponding printed patterns.
Specifically, the depth-width ratio requirement of the printed patterns of bigger block (such as: electrically connection pad) in corresponding electronic circuit
Relatively low, and in corresponding electronic circuit, the depth-width ratio of the printed patterns of smaller block (such as: wire) requires higher.Therefore, in shape
When the part longitude and latitude becoming through hole 211 and removal screen cloth 20 organizes 201, can be if necessary on the ink bleed path of same through hole 211
The longitude and latitude tissue 201 of member-retaining portion, makes through hole 211 connect the first of screen cloth 20 without longitude and latitude tissue area 202 and second without longitude and latitude
Tissue area 203, as shown in Fig. 6 A, Fig. 6 B；Or form connection first respectively without the relatively large through-hole 212 of longitude and latitude tissue area 202 and company
Logical second without the relatively small through hole 213 of longitude and latitude tissue area 203, as shown in Fig. 6 A, Fig. 6 B.By combining various sizes of through hole 211,
212,213 with the first of each connected screen cloth of through hole 211,212,213 20 without longitude and latitude tissue area 202 and second without longitude and latitude tissue
District 203, can maintain the tension force of half tone pattern 2, can print out again the electronic circuit having splendid resolution with depth-width ratio.
In sum, this utility model utilizes the through hole of the connection macromolecule layer of tissue area without longitude and latitude of screen cloth, can effectively keep away
Exempt from the barrier in the via path of half tone pattern and affect the ink bleed uniformity, thus promote precision and the quality of printed patterns, symbol
Close electronic circuit demand now.
Above-described embodiment only illustrative principle of the present utility model and effect thereof are new not for limiting this practicality
