Abstract

The invention relates to the technical field of removing conductive materials by a chemical or electrolytic method, especially to a circuit board production apparatus comprising an etching box and a covering part. The covering part consists of an annular ring and a cover plate arranged at the center of the annular ring; and connecting rods are connected between the cover plate and the annular ringand an exhausting hole is formed between each two adjacent connecting rods. A rotating plate that can cover the exhausting holes is connected between the annular ring and the cover plate in a rotation manner; and a torsion spring is arranged at the rotating plate. A placing part is arranged inside the etching box; an annular slot is formed in the inner wall of the etching box; a cavity is formedin the wall of the etching box; a connection cavity is communicated between the bottom of the annular slot and the cavity; a sliding plate is arranged in the connection cavity in a sliding connectionmanner; a pull rod is fixed at the sliding plate; and a protrusion is fixed at the annular ring. An L-shaped slot is formed in the inner wall of the etching box; and an elastic layer is arranged at the bottom of the L-shaped slot. Therefore, problems that the etching liquid is easy to splash out of the etching box at the stirring time and irritant gas can not be exhausted quickly in the etching box in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of removing conductive materials by chemical or electrolytic methods, in particular to a circuit board production device. Background technique [0002] With the development of social economy and the continuous improvement of people's consumption level, the use of electronic equipment is becoming more and more extensive. At this stage, the circuit board in electronic equipment is an extremely important part. Therefore, in order to better control the circuit The surface of the board is processed, and a large number of printed circuit board production and processing devices have appeared in the society. [0003] Usually, the circuit board needs to go through many processes in the manufacturing process before it can be prepared into a finished product. Among them, the etching process of the circuit board is one of the most critical processes in the entire manufacturing process of the circuit board. The main pur...
