Double-position alternating type numerical control high-speed printed circuit board electric spark etching equipment

Abstract

The invention discloses double-position alternating type numerical control high-speed printed circuit board electric spark etching equipment, belongs to the field of circuit boards, and solves the problems that in the prior art, when conductive materials of a printed circuit board are etched in an electric spark mode, generated impurities are partially mixed in a liquid medium and partially attached to the surface of the circuit board, impurities need to be removed after the circuit board is taken out, and etching is interrupted when an electrode tip needs to be replaced in the assembling process in the etching process. When the liquid medium is discharged, the liquid medium is dragged to perform one-way surging, on one hand, impurities mixed with the liquid medium are dragged to surge away from the circuit board and be discharged along with the liquid medium, and on the other hand, the impurities attached to the surface of the printed circuit board are slightly brushed to be separated from the surface of the circuit board and discharged along with the liquid medium. Through cooperation of the two etching mechanisms, electrode tip replacement is achieved, and the etching process is uninterrupted.

Description

technical field [0001] The invention relates to the field of circuit boards, in particular to the field of removing conductive materials of printed circuit boards, and in particular to a double-position alternating numerical control high-speed printed circuit board electric spark etching equipment. Background technique [0002] Printed circuit boards are widely used in various electronic fields because of their high wiring density, small size, light weight, and standardized design. The manufacturing methods of printed circuit boards can be divided into subtractive and additive methods. Among the forming methods, the copper foil corrosion method is the main method. When the circuit boards are mass-produced, the chemical liquid corrosion method is the main method. Before, it was necessary to make a sample in the laboratory for various performance tests. At this time, if the chemical solution corrosion method suitable for mass production of circuit boards is selected, the chemi...

Problems solved by technology

[0003] In order to solve the existing technology, when the conductive material of the printed circuit board is etched by the electric spark method, the fine impurities generated by the etching are partially mixed in the liquid medium and partially adhered to the surface of the circuit board. After the circuit board is taken out, impurities need to be removed. problem, and in the process of electric spark etching, because the assembly process needs to replace the electrode head, the problem of intermittent etching will occur. The present invention proposes a double-position alternating numerical control high-speed printed circuit board electric spark etching equipment
