A circuit board corrosion device for accelerated corrosion

Abstract

The invention relates to the technical field of circuit boards, and discloses a circuit board corrosion-accelerating device, which includes a base, an organism is arranged outside the base, an annular curved plate is arranged inside the body, and an air outlet plate is arranged inside the body. It also includes: a power mechanism for small reciprocating rotation of the body, the power mechanism is set outside the base; through the use of power mechanism, air flow mixing mechanism, valve mechanism, control mechanism, clamp mechanism, etc.; solves the traditional circuit board corrosion In the test, due to the problem that the pulling wire and the circuit board were all immersed in the solution due to carelessness, it can be ensured that the circuit board will not come into contact with the inner wall of the container during the circuit board corrosion test, which will cause the transfer area to be scratched. The circuit board can be completely corroded, and the circuit board can be taken safely, and it will also solve the problem of different concentrations of corrosion solutions at different depths caused by long-term circuit board corrosion.

Description

technical field [0001] The invention relates to the technical field of circuit boards, in particular to a circuit board corrosion device for accelerated corrosion. Background technique [0002] In some electrical experiments or physical production, the school will let students try to make circuit boards by themselves. The more commonly used methods are the corrosion circuit printed circuit method and the knife carving method, and the knife carving method is only suitable for making small circuit boards. Large, so the corrosion printing method is mostly used, and the corrosion printing is divided into electrolytic corrosion and solution corrosion. [0003] In university circuit experiments, students are generally required to process a small circuit board according to the drawings. In the process of making circuit boards, students are often required to perform solution etching after completing the heating transfer operation of the circuit board. However, existing Due to the l...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an accelerated corrosion circuit board corrosion device, which has the advantages of adapting to circuit boards of different specifications, consistent solution concentration, and safety, and solves the problem that many existing schools have limited teaching conditions. Put the corrosion solution in the container, let the students pull the circuit board with the wire and put it into the container, but this kind of operation will cause the problem that the wire and the circuit board are all immersed in the solution, which is not conducive to the students to take the circuit board , and many circuit boards are corroded together, which will make the solution concentration in the container different, and the problem of corrosive gas will appear during the corrosion process
