An etching device for printed circuit board production

Abstract

The invention discloses an etching device for printed circuit board production, which relates to the field of printed circuit production, and comprises an etching box, two sets of oppositely arranged transmission racks are installed above the etching box, and the interior of each set of transmission racks is There are conveyor belts for installation, and multiple sets of suspenders are connected between the two sets of conveyor belts. The inner wall of the etching box is provided with a guide mechanism, and the outer wall of each set of suspenders is equipped with a hanging plate, and the bottom of the hanging plate is set With fixed frame. In the present invention, through the provided guide rails and tooth plates, the tooth plates in the guide rails are arranged at intervals, so that when the fixed frame moves, the helical gear and the tooth plate are in contact with each other at intervals, so that the fixed frame rotates intermittently with the helical gear, and the circuit board is adjusted once. , it will stay for a long time, so that the part blocked by the limit roller before the circuit board can fully contact with the etching solution, and improve the uniformity of etching.

Description

technical field [0001] The invention relates to the field of printed circuit production, in particular to an etching device for the production of printed circuit boards. Background technique [0002] Printed circuit refers to the use of various printing methods (such as embossing, plating, corrosion) or the use of "film circuit" technology to separate or interconnect wires, contacts or other printed components, inductors, resistors, and capacitors according to predetermined patterns. Circuits printed contiguously on an insulating substrate, other than components capable of generating, rectifying, modulating or amplifying electrical signals, such as semiconductors. Does not include circuits incorporating non-printed components, nor does it include individual discrete resistors, capacitors and inductors, except that printed circuits may be provided with non-printed connecting Etching is a key step. Generally, the circuit board is placed in an etching solution, and the copper ...

AI Technical Summary

Problems solved by technology

[0004] Based on this, the object of the present invention is to provide an etching device for the production of printed circuit boards, to solve the technical problems that it is not convenient to etch all aspects of the circuit board, and the concentration of the liquid on the outside of the circuit board is inconvenient to restore.
