A double-position alternating numerical control high-speed printed circuit board electric spark etching equipment

Abstract

The invention discloses a double-position alternating numerical control high-speed printed circuit board electric spark etching equipment, which belongs to the field of circuit boards, and solves the problem of impurities generated when the printed circuit board is etched with conductive materials by means of electric sparks in the prior art Mixed in the liquid medium, partly attached to the surface of the circuit board, the problem of impurity removal after the circuit board is taken out, and the problem of intermittent etching when the electrode tip needs to be replaced due to the assembly process during the etching process; while the liquid medium is discharged, it is pulled The liquid medium surges in one direction. On the one hand, the traction itself surges away from the circuit board with the impurities mixed with the liquid medium and is discharged with the liquid medium. On the other hand, the impurities attached to the surface of the printed circuit board are gently flicked to remove them The surface of the circuit board is discharged along with the liquid medium. Through the cooperation of two sets of etching mechanisms, the replacement of the electrode head is realized but 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
