Problems solved by technology

Its disadvantages are: it can only be used for plates with a relatively small number of holes, and for denser holes, due to the overlapping of holes, the middle of the air guide plate will fall off, lack of support points, and it will not be used

Embodiment

[0017] refer to image 3 , a printed air guide plate, including a substrate 1, the substrate 1 is provided with a borehole through the substrate, the borehole is composed of a first borehole 2 and a second borehole 3, the second borehole 2 Located above the first borehole 3 , and the second borehole 2 communicates with the first borehole 3 .

[0018] In this embodiment, the drilled holes penetrating the substrate are in an inverted "convex" shape.

[0019] In this embodiment, the thickness of the substrate 1 is 2.0mm.

[0020] In this embodiment, the diameter of the first borehole 2 is 0.4mm.

[0021] In this embodiment, the drilling depth of the second drilling 3 is 1.2mm, and the diameter is 2.0mm (ensure that the diameter of the hole is 1.0mm larger than that of the plug hole to prevent the ink from sticking to the air guiding plate).

[0022] Its production method: use a 2.0mm substrate as the carrier, use a 0.4mm drill bit to drill through, and use 2.0mm at the positio...

Abstract

Disclosed is a printed gas-guiding board. The printed gas-guiding board comprises a substrate, wherein drilling holes, which consists of a first drilling hole and a second drilling hole, are formed in the substrate in a run-through manner; the second drilling hole is formed above the first drilling hole; and the second drilling hole is connected with the first drilling hole. The printed gas-guiding board has a good gas-guiding effect; completeness and non-falling-off of the gas-guiding board can be ensured specific to a dense pore board; and the problems existing in the prior art can be effectively overcome.

Description

technical field [0001] The invention relates to a manufacturing tool for solder resist ink plug holes and resin ink plug holes in PCB manufacturing process, in particular to a printing air guide plate. Background technique [0002] In the PCB manufacturing process, in order to achieve the electrical performance of the inner and outer layers of the PCB board, mechanical drilling is usually used to penetrate the PCB substrate, and then the dielectric layer of the hole wall is metallized (copper sinking, copper plating) to achieve electrical conduction. Performance; in order to ensure the long-term stability of the electrical performance and reliability of PCB products (referring to the long-term stability and reliability of product quality, collectively referred to as reliability), the process technology will be implemented for Via (over-electricity) holes, solder resist ink or resin ink The plug hole filling operation completely blocks the Via hole, making it impossible to st...
