Abstract
The invention discloses a purification device of a PCB (printed circuit board) etching liquid medicine. The purification device comprises an etching groove, a liquid medicine tank for containing an OSP (organic solderability preservatives) antioxidant and a sprayer nozzle assembly, wherein the liquid medicine tank is positioned and placed at the periphery of the etching tank and is communicated with the etching tank by virtue of the sprayer nozzle assembly; a reflux outlet and a reflux inlet are positioned and formed on the liquid medicine tank and are communicated by virtue of a circulating pipeline, and the circulating pipeline is further provided with a circulating pump device; in addition, a filter dreg screen is positioned and arranged at the reflux outlet and a purification piece for breaking foam and adsorbing oil stains are positioned and formed at the reflux inlet, so that not only can air bubbles generated by circulating the OSP antioxidant liquid medicine be broken, but also the air bubbles can be decomposed to suspended oil stains which are adsorbed, thereby effectively reducing the oil stains carried when the OSP antioxidant liquid medicine is circulated, preventing the surface of the PCB from being polluted and improving the yield of the PCBs.
Description
Technical field
The present invention relates to printed-board technology field, a kind of refining plant of printed circuit board (PCB) etching solution is specifically provided.
Background technology
At the later stage that printed-wiring board (PWB) makes, the pad in type plate face is oxidizable, thus causes tin on pad bad, can not form firmly solder joint, occur rosin joint, the phenomenons such as scolding tin is not full.In order to solve this defect, a chemical technology in existing printed-wiring board (PWB) making processes, is usually adopted to make up.This chemical technology is called as OSP organic protective film technique: namely at the organic membrane that naked copper Surface Creation one deck is firm; this film no longer continues oxidation in order to protect copper face in normal environment; under welding high temperature afterwards, protective membrane is easily removed by soldering flux, can form firmly solder joint in very short time with molten tin.
But in the film process of OSP organic protective film; because OSP antioxidant liquid medicine circulation time can produce bubble and then liquid medicine can be caused to resolve into the greasy dirt of suspension; thus when OSP antioxidant liquid medicine is sprayed onto on the surface of pcb board, copper face can be caused heterochromatic, be unfavorable for product yield.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of refining plant of printed circuit board (PCB) etching solution, this is simple and reasonable for structure, and the bubble that can produce antioxidant liquid medicine circulation time carries out brokenly bubble and processes and adsorb greasy dirt, effectively improves the yield of printed circuit board (PCB).
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of refining plant of printed circuit board (PCB) etching solution, comprise etching bath, in order to the processing solution tank of splendid attire OSP antioxidant and nozzle component, described processing solution tank location is arranged at the periphery of described etching bath, and described processing solution tank is communicated with described etching bath by described nozzle component; On described processing solution tank, locating open is provided with phegma outlet and phegma entrance, and described phegma outlet is connected by circulation line with phegma entrance, and is also provided with recycle pump pump apparatus on described circulation line; Separately location, described phegma exit is provided with skim strainer, is also provided with in order to broken bubble in location, described phegma ingress and adsorbs the purification part of greasy dirt.
As a further improvement on the present invention, the inner bottom surface of described processing solution tank is formed with a groove, described phegma outlet locating open is located in described groove, and described skim strainer location is layed in described groove, and can cover the outlet of described phegma.
As a further improvement on the present invention, described purification part comprises brokenly silk damping net and oil absorbent material;
Described phegma entrance locating open is located on the sidewall of described processing solution tank, and the structure that described purification part location is arranged at described phegma ingress is: be also provided with a support for accepting the liquid ejected from described phegma entrance, on the inner side-wall that described support location is arranged on described processing solution tank and near the position be positioned at below described phegma entrance, described oil absorbent material location is layed on described support, and described broken silk damping net location is layed on described oil absorbent material.
As a further improvement on the present invention, described nozzle component comprises multiple jet pipe, the plurality of jet pipe is disposed on the sidewall of described etching bath, and one end of the plurality of jet pipe all communicates with the inside of described etching bath, and the other end of the plurality of jet pipe all communicates with the inside of described processing solution tank.
The invention has the beneficial effects as follows: pass through structure innovation, on processing solution tank, locating open is provided with phegma outlet and phegma entrance, described phegma outlet is connected by circulation line with phegma entrance, and also location, described phegma exit is provided with skim strainer, locate on the inner side-wall of described processing solution tank and near the position be positioned at below described phegma entrance and be provided with brokenly silk damping net and oil absorbent material, thus the bubble that OSP antioxidant liquid medicine circulation time produces can not only be carried out fragmentation, suspension greasy dirt can also be broken down into and adsorb simultaneously, effectively reduce the greasy dirt entrained by OSP antioxidant liquid medicine circulation time, avoid pcb board surface contaminated, improve the yield of pcb board.
