Description

Technical Field

[0001] This utility model relates to the field of circuit board printing technology, and in particular to a circuit board structure for manufacturing precision printed circuits. Background Technology

[0002] When creating conductive circuit patterns on circuit boards using printing methods, limitations often exist in the width and spacing of the lines. Firstly, printing precise lines often requires increasing the mesh count of the stencil; however, a higher mesh count means less ink can be applied, resulting in thinner printed lines that are insufficient for adequate conductivity. Secondly, the fluidity of the conductive ink can cause the lines to widen. When two lines are very close together, they can easily short-circuit.

[0003] Considering both of these factors, existing printing processes restrict the production of precision circuits. Utility Model Content

[0004] The technical problem to be solved by this utility model is: In order to solve the technical problems in the prior art, this utility model provides a circuit board structure for manufacturing precision printed circuits.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a circuit board structure for manufacturing precision printed circuits, including a substrate body, a baffle wall provided on the substrate body, and the baffle wall being disposed between adjacent conductive lines.

[0006] This utility model discloses a circuit board structure for manufacturing precision printed circuits. By setting a barrier between adjacent conductive lines, it can effectively prevent the conductive ink of the two conductive lines from contacting, thereby preventing short circuits. At the same time, when applying conductive ink, the thicker the conductive ink, the wider the conductive ink spreads on the circuit board, which may lead to short circuits between adjacent conductive lines. The barrier facilitates the printing of thicker ink and is suitable for circuit boards that require printing thicker ink.

[0007] Furthermore, the retaining wall is located at the edge of the substrate body.

[0008] With the above technical solution, the barrier is set at the edge of the substrate body, which can prevent the conductive ink from spreading too close to the edge, thereby avoiding the problem of easy discharge at the edge.

[0009] Furthermore, the height of the retaining wall is 10-30 micrometers.

[0010] Furthermore, the width of the retaining wall is 50-300 micrometers.

[0011] Furthermore, when multiple baffles are provided on the same substrate body, the distance between adjacent baffles is greater than the width of the ink application.

[0012] Furthermore, the retaining wall is made of solder resist ink.

[0013] Furthermore, the retaining wall has a rectangular cross-section.

[0014] Furthermore, the retaining wall has a triangular cross-section.

[0015] Furthermore, the scraper is made of a material with a hardness of 45 to 70.

[0016] Furthermore, the scraper is made of a material with a hardness of 65.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting up a barrier between adjacent conductive lines, it is possible to effectively prevent the conductive ink of the two conductive lines from contacting each other, thereby preventing short circuits. At the same time, when applying conductive ink, the thicker the conductive ink, the wider the conductive ink spreads on the circuit board, which may lead to short circuits between adjacent conductive lines. The barrier is conducive to printing thicker ink and is suitable for circuit boards that require printing thicker ink.

[0019] 2. The barrier is set at the edge of the substrate body to prevent the conductive ink from spreading too close to the edge, thereby avoiding the problem of easy discharge at the edge. Attached Figure Description

By providing the baffle 2 between adjacent conductive lines, the conductive ink of the two conductive lines can be effectively prevented from contacting, thereby preventing short circuits. Furthermore, when applying conductive ink, the thicker the ink, the wider the ink spreads on the circuit board, increasing the likelihood of short circuits between adjacent conductive lines. The baffle 2 facilitates the printing of thicker ink, making it suitable for circuit boards requiring thicker ink printing.

[0028] The barrier 2 is located at the edge of the substrate body 1. The barrier 2 is located at the edge of the substrate body 1 to prevent the conductive ink from spreading too close to the edge, thereby avoiding the problem of easy discharge at the edge.

[0030] When multiple baffles 2 are set on the same substrate body 1, the distance between adjacent baffles 2 is greater than the width of the ink application.

[0031] The cross-section of retaining wall 2 is rectangular.

[0032] In another embodiment, the retaining wall 2 has a triangular cross-section.

[0033] Referring to the figure, the stencil 3 is pressed down by the squeegee 4, and ink is printed on the substrate body 1. The squeegee 4 used has a material hardness of 45 to 70. In this embodiment, the squeegee 4 has a material hardness of 65.

[0034] Working principle: By setting a barrier 2 between adjacent conductive lines, the conductive ink of the two conductive lines can be effectively prevented from contacting, thereby preventing short circuits. Furthermore, when applying conductive ink, the thicker the ink, the wider it spreads on the circuit board, increasing the likelihood of short circuits between adjacent conductive lines. The barrier 2 facilitates printing thicker ink, making it suitable for circuit boards requiring thicker ink application. The barrier 2 is positioned at the edge of the substrate body 1 to prevent the conductive ink from spreading too close to the edge, thus avoiding the problem of easy discharge at the edge.
