Abstract

The invention discloses a circuit board etching method, belongs to the field of circuit board processing, and provides the following scheme that a circuit board etching device comprises a first workbench, and a rotation damping piece arranged in the width direction of the first workbench is rotationally installed above the left side of the first workbench; a long fixing piece perpendicular to the rotating damping piece is fixed to the right side face of the rotating damping piece, the other end of the long fixing piece is fixed to the right side of an L-shaped connecting angle plate parallel to the rotating damping piece, and the L-shaped connecting angle plate is detachably connected with the first workbench through a locking bolt. The bottoms of the rotary damping pieces and the bottoms of the L-shaped connecting angle plates are connected with circuit board pressing pieces through elastic telescopic pieces, wherein the circuit board pressing pieces are arranged in the width direction of the first workbench. According to the spraying mode, it can be guaranteed that etching liquid moves vertically as far as possible, the etched etching liquid flows down, the problem of lateral etching is avoided, and the etching quality of the circuit board can be improved.

Description

technical field [0001] The invention relates to the technical field of circuit board processing, in particular to a circuit board etching method. Background technique [0002] The names of circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. [0003] With the advancement and refinement of science and technology, the requirements for the basic material of electronic components - circuit boards are also getting higher and higher, and in the process of circuit board etching, ideally, we hope ...
