Problems solved by technology

[0002] The original design of the acid etching machine is mainly to produce double-sided boards. The double-sided boards are etched by spraying up and down. When using a single-sided circuit board, the etching machine can only use the upper spraying, resulting in the lower spraying not playing its due role, resulting in equipment utilization. Low cost, various costs are wasted, the speed of etching and film removal in the original design is 12 m / min, and the productivity is very low in the case of single-sided circuit board production

Embodiment 1

[0016] A kind of rapid etching method of single-sided circuit board, comprises the following steps:

[0017] 1) Put two single-sided circuit boards together;

[0018] 2) Spray the upper and lower single-sided circuit boards with an acid etching machine for etching;

[0019] 3) After the over-etching section, remove the film separately.

[0020] In step 2), the etching speed is 24 m / min; in 3), the speed of the film-removing section is increased to the fastest 20 m / min by changing the frequency converter.

[0021] In the present invention, since the speeds of the etching and film-removing sections in the original design are both 12 m / min, the production capacity of the single-panel is doubled after the front and back of the improved single-panel are combined and placed. The rapid etching method of the single-sided circuit board of the present invention is simple to operate, can improve work efficiency, double production efficiency, and can save various costs.

Abstract

The invention discloses a rapid etching method for a single-sided circuit board, which comprises the following steps: 1) combining and placing two single-sided circuit boards; 2) spraying the upper and lower two single-sided circuit boards with an acid etching machine Etching; 3), after the etching section, remove the film separately. The rapid etching method of the single-sided circuit board of the present invention is simple to operate, can improve work efficiency, double production efficiency, and can save various costs.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to a rapid etching method for a single-sided circuit board. Background technique [0002] The original design of the acid etching machine is mainly to produce double-sided boards. The double-sided boards are etched by spraying up and down. When using a single-sided circuit board, the etching machine can only use the upper spraying, resulting in the lower spraying not playing its due role, resulting in equipment utilization. Low cost, various costs are wasted, the speed of the etching and film removal section in the original design is 12 m / min, and the productivity is very low in the case of producing single-sided circuit boards. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies of the prior art, the present invention aims to provide a rapid etching method for a single-sided circuit board.
