Problems solved by technology

[0004] However, in the above recovery method, due to the inability to effectively control the reaction speed or degree of copper ions and metallic iron in the waste liquid in the waste liquid tank, the metal copper that has been reacted in the waste liquid cannot be separated from the waste liquid tank in time, and Metal copper will be oxidized to cuprous ion by ferric chloride
In this way, unnecessary waste will be caused, and the cycle of recycling waste liquid will be increased.

Abstract

The invention provides a waste liquor recovery device which comprises a reducing agent-supplying device, a waste liquor-guiding device and a conveyer belt, wherein the waste liquor-guiding device andthe conveyer belt are arranged opposite to the reducing agent-supplying device; the waste liquor-guiding device comprises an injection end for providing the conveyer belt with waste liquor; one end ofthe conveyer belt is close to the reducing agent-supplying device, and the other end is close to the injection end; the reducing agent-supplying device is used for providing the conveyer belt with areducing agent; the transmission direction of the conveyer belt enables the reducing agent to move towards one end of the conveyer belt close to the injection end; and the conveyer belt is obliquely arranged so that the flowing direction of the waste liquor on the conveyer belt is opposite to the transmission direction. The invention also provides a waste liquor recovery method.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to a recovery device for waste liquid generated during the production process and a waste liquid recovery method. Background technique [0002] Wet Process (Wet Process), as a production process in the process of making circuit boards, is to spray processing liquids, such as various chemical liquids or water, on the surface of circuit substrates to achieve plated through holes, copper plating, etching, development, and stripping , organic protective film coating, surface modification or cleaning processes. Document K.W.Lee, A.Viehbeck, Wet Process Surface Modification of Dielectric Polymers, IBM J.Research & Development, 1994, 38 (4) introduces a method for surface modification of insulating layer and adhesive layer in circuit board by wet process , to improve the bonding force between the insulating layer and the metal layer in the circuit board. [0003] Usually...
