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...
