[0032] Reference Figures 1 to 4 , a method for making a silk screen plugging pad comprises the following steps:

[0033] Cutting the material: selecting FR-4 material for cutting according to the design dimensions of the first board 100 and the second board 200;

[0034] Drilling: stack the first plate 100 and the second plate 200 together, and drill a positioning hole 300 near the top corner;

[0035] Etching to separate the first plate 100 and the second plate 200, and then respectively etching the first plate 100 and the second plate 200 after drilling into bare plates;

[0036] Milling grooves: a laser is used to mill a plurality of first through grooves 110 on the first plate 100, the first through grooves 110 are arranged in a hexagonal shape, and the plurality of first through grooves 110 are distributed in a honeycomb shape. The laser head is translated for a certain distance, and a plurality of second through grooves 210 are milled on the second plate 200, the second through grooves 210 are arranged in a hexagonal shape, and the plurality of second through grooves 210 are distributed in a honeycomb shape. After the first through grooves 110 and the second through grooves 210 are milled, the milling depth is controlled and then the laser is used to mill the air guide grooves 400 at the lower end of the first plate 100 and / or the second plate 200, so that each of the first through grooves 110 and the second through grooves 210 corresponds to two air guide grooves 400;

[0037] Cleaning: Cleaning and drying the first plate 100 and the second plate 200 respectively;

[0038] During installation, the first plate 100 and the second plate 200 are stacked and fixed in position through the positioning holes 300 so that the first through groove 110 and the second through groove 210 are staggered by a certain distance. The first plate 100 and the second plate 200 are stacked to form a complete pad, which is used for silk screen printing.

[0039] The first plate 100 and the second plate 200 are stacked so that the first through groove 110 and the second through groove 210 are staggered and overlapped. Compared with the existing method of one circuit board corresponding to one pad, the method produces a universal silk-screen plugging pad. When switching between different types of circuit boards, the pad can meet the use requirements and is not limited by the hole positions and hole sizes on different types of circuit boards. This solves the problem of silk-screen plugging process that different types of circuit boards need to prepare pads of corresponding specifications when plugging holes, thereby greatly avoiding the waste of pad materials and processing.

[0040] It can be understood that the stacking of the first plate 100 and the second plate 200 increases the vertical height to facilitate exhaust. In addition, when the first plate 100 and the second plate 200 are stacked, the first through groove 110 and the second through groove 210 will be staggered by a certain distance to ensure the support of the first plate 100 and the second plate 200 when they are stacked. When the air guide groove 400 is set on the first plate 100 and the second plate 200, the first plate 100 and the second plate 200 do not need to distinguish between the upper and lower positions and can be directly stacked for easy use; the milling groove is performed by laser, and the laser cuts out the corresponding through groove. Of course, other cutting methods can also be selected. In the etching step, the first plate 100 and the second plate 200 are respectively etched into light plates in order to make the surface gloss of the first plate 100 and the second plate 200 reach a predetermined level to avoid being contaminated with plugging ink and being unable to remove it, so that the first plate 100 and the second plate 200 can be recycled and the service life is extended.

[0041] In some embodiments, in the cutting step, the length and width of the first plate 100 and the second plate 200 are 21 inches×24 inches, and the thickness is 0.8 mm, where inch means inches, which is a commonly used unit in the industry.

[0042] In some embodiments, in the drilling step, the aperture of the positioning hole 300 is 1 mm. It can be understood that the positioning holes 300 on the first plate 100 and the second plate 200 correspond to each other vertically, and the positioning holes 300 on the first plate 100 are distributed at the top corners close to the first plate 100. At least three of the four top corners of the first plate 100 are provided with positioning holes 300 because three points locate a plane so that the first plate 100 and the second plate 200 are in a horizontal plane.

[0043] In some embodiments, in the groove milling step, the hexagon is a regular hexagon, the hexagonal side length of the first through groove 110 and the second through groove 210 is 0.5 mm, and the wall thickness between two adjacent first through grooves 110 and the wall thickness between two adjacent second through grooves 210 are both 0.3 mm. It can be understood that translating the laser head a certain distance refers to translating the laser head by half the length of the diagonal, and the diagonal value is the line connecting the two opposite corners of the regular hexagon.

[0044] In some embodiments, in the milling step, the air guide groove 400 is a square, and the side length of the square is 0.3 mm. It can be understood that the square shape of the air guide groove 400 means that the outer contour of the slot space is a square, and the air guide groove 400 is used for exhaust. It can be understood that the bottom surfaces of the first board 100 and the second board 200 are both provided with air guide grooves, and the air guide groove 400 is connected to the outside world, so that it can support the circuit board and make the ink of the plugging hole of the circuit board flow downward. When the plugging hole ink flows downward, the air guide groove 400 exhausts air to ensure the smoothness of the plugging hole ink flowing downward, and of course, it also ensures the fullness of the circuit board plugging hole. The so-called square shape actually means that the cross section of the air guide groove 400 is a square.

[0045] In some embodiments, in the groove milling step, the translation distance of the laser head is half the length of the diagonal of the hexagon, and a plurality of diamond-shaped through grooves are formed after the first plate 100 and the second plate 200 are superimposed.

[0046] In some embodiments, in the milling step, the air guide groove 400 is arranged on two opposite walls of the first through groove 110 or the second through groove 210. It can be understood that the air guide groove 400 is arranged on the bottom surface of the first plate 100 or the second plate 200, and the so-called bottom surface is the lower end surface, and the air guide groove 400 is arranged on two opposite walls of the first through groove 110 or the second through groove 210, so the air guide groove 400 appears as a square notch on the two opposite walls of the first through groove 110 or the second through groove 210.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
