Problems solved by technology

[0003] But at present, in the desmearing and copperizing steps, the plate is usually driven by horizontal movement. In order to ensure that the plate can fully carry out the chemical reaction, the length of the equipment corresponding to the desmearing and copperizing steps is generally longer. As a result, the length of the entire desmear and copper removal line is increased, so that it is not suitable for installation and use in general small factories, and the efficiency and quality of desmear and copper treatment are not high, so it needs to be improved

Abstract

The invention relates to a horizontal glue residue removal and copper assembly line. The horizontal glue residue removal and copper assembly line sequentially comprises an automatic plate placement machine, a plate grinding machine group, a first washing groove group, a first operation station, a first surface processing system, a second washing groove group, a second surface processing system, athird washing groove group, a pre-neutralizing groove, a fourth washing groove group, a re-neutralizing groove, a fifth washing groove group, strong air drying equipment, a second operation station, afirst hot water knife immersion groove, a hole shaping machine, a sixth washing groove group, a micro-etching groove, a seventh washing groove group, a pre-immersion groove, a third surface processing system, an eighth washing groove group, a reduction groove, a ninth washing groove group, a fourth surface processing system, a tenth washing groove group, a drying groove group, an automatic platereceiving machine and a transmission mechanism, wherein a plate is driven to rotate by the first surface processing system, the second surface processing system, the third surface processing system and the fourth surface processing system so as to be in contact with a corresponding surface processing liquid. The horizontal glue residue removal and copper assembly line has the effects of relativelyshort length, high processing efficiency and good quality.

Description

technical field [0001] The invention relates to the technical field of surface treatment of circuit boards, in particular to a horizontal slag and copper removal line and a method for removing scum and copper. Background technique [0002] Printed PCB board (circuit board) is the basic product of modern electronics and information industry. The printed circuit board is based on the pre-designed circuit, and the conductive pattern used for the connection between the components is formed on the surface of the board. There are as many as 20 processes in the manufacturing process. At present, the production process of printed circuit boards includes a series of surface treatment processes to treat the surface of the board, such as: desmear, electroless copper (copper), nickel plating, tin stripping, nickel, gold, chemical Nickel Gold etc. [0003] But at present, in the desmearing and copperizing steps, the plate is usually moved in a horizontal motion. In order to ensure that...
