Description
Technical field
The utility model is related to the de-bubble fields of circuit board preparation process liquid medicine, and in particular to a kind of pcb board technique liquid medicine
Defoaming system.
Background technology
In pcb board manufacturing, after the transfer of PCB figure and pictures, photosensitive material just needs to get rid of and (develop, move back film), and
It is to use alkaline solution to remove this photosensitive material all.Liquid medicine (sodium carbonate/potassium carbonate) will produce a large amount of foam in pcb board technique
Influence making sheet effect.Common defoaming foam mode is to carry out elimination foam by a kind of antifoaming agent of addition.The defoaming process needs
Add a large amount of antifoaming agent.And the amount for the antifoaming agent being added is excessive, can increase cost of manufacture.And the antifoaming agent in subsequent handling
It is cleaning dirty to hinder etch capabilities, keep etching not clean.Simple can not reach optimal effect using antifoaming agent.
Utility model content
The utility model provides a kind of defoaming system for PCB making sheet, is mutually tied with chemistry defoaming using pressure change
The method of conjunction solves and chemical defoaming mode is used only in the prior art, and causes PCB making sheet etching not clean higher with cost
Problem.
The utility model is achieved through the following technical solutions：
The base case of the utility model is：
Pcb board technique liquid medicine defoaming system, including solution tank, antifoaming agent medicinal cupping, the antifoaming agent medicinal cupping pass through inlet tube
It is connect with the solution tank, the inlet tube is equipped with solenoid valve, and the antifoaming agent medicinal cupping is connected with air pressure regulator；It is described molten
Liquid bath is equipped with upper cover, and the junction of the upper cover and solution tank is equipped with sealing element；The top of the solution tank by escape pipe and
Air inlet pipe is connected separately with air extractor and inlet duct.
Operation principle：After pcb board is placed into the solvent of solution tank, upper cover is covered.Air extractor is evacuated, and is changed
Pressure in solution tank breaks the pressure balance of bubble in solution tank, and the bubble originally sticked on pcb board is made to float on the surface of the water.
For the bubble of liquid surface, due to the gas contact directly and in solution tank, when the air pressure in solution tank reduces suddenly, liquid
The pressure balance of the bubble in body surface face is seriously damaged, and the bubble on surface is made to rupture.Air extractor only need to be in appropriate degree
Interior pumping pressure, makes its pressure change reach certain value.Antifoaming agent medicinal cupping is sent into antifoaming agent to the solution in solution tank, makes
Bubble is not easy to generate and retain in the solution.The amount that antifoaming agent is added increases, and the decompression needed for solution tank de-bubble is smaller.Defrother
It complements each other with decompression the two, the common work for completing de-bubble.
Advantageous effect：The method of physics de-bubble and chemical de-bubble is combined by the utility model, is avoided using only chemistry
Defoaming mode, defrother are excessively used, it is difficult to clean up, be impacted to the subsequent handling of pcb board.Air pressure regulator is given
Give the certain pressure of antifoaming agent medicinal cupping.After solenoid valve is opened, the pressure in antifoaming agent medicinal cupping is automatically sent medicament by inlet tube
Enter solution tank.It no longer needs to, by hydraulic pump liquor charging, keep device simpler, integrated.
One preferred embodiment of the utility model, wherein：The air extractor is vacuum pump.Vacuum pump can be realized to molten
Liquid bath vacuumizes required effect.
One preferred embodiment of the utility model, wherein：The inlet duct includes intake valve, is equipped in the intake valve
Air inlet cushion pad.It is finished when air extractor is evacuated, after bubbles burst.The preferably more slow air inlet of inlet duct, to avoid gas
Stream impact is excessive to impact pcb board.Air inlet cushion pad can enter solution tank to air-flow and play the role of buffering.
One preferred embodiment of the utility model, wherein：The sealing element is ring type seal made of soft plastic.Ring
Shape sealing ring can seal upper cover and solution tank.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments：
Fig. 1 is the structural schematic diagram of the utility model.
Reference numeral：Solution tank 6, upper cover 2, antifoaming agent medicinal cupping 5, air pressure regulator 4, solenoid valve 3, air extractor 1, air inlet
Device 7.
Specific implementation mode
Pcb board technique liquid medicine defoaming system as shown in Figure 1, including solution tank 6, antifoaming agent medicinal cupping 5, antifoaming agent medicinal cupping 5
It is connect with solution tank 6 by inlet tube, inlet tube is equipped with solenoid valve 3.Antifoaming agent medicinal cupping 5 is connected with air pressure regulator 4.Air pressure
Regulating valve 4 gives antifoaming agent medicinal cupping 5 certain pressure.After solenoid valve 3 is opened, the pressure in antifoaming agent medicinal cupping 5 is automatically by medicament
It is sent into solution tank 6 by inlet tube.It no longer needs to, by hydraulic pump liquor charging, keep device simpler, integrated.Solution tank 6 is equipped with upper
Lid 2, upper cover 2 and the junction of solution tank 6 are equipped with sealing element.Sealing element is ring type seal made of soft plastic.Solution tank 6
Top air extractor 1 and inlet duct 7 are connected separately with by escape pipe and air inlet pipe.Air extractor 1 is vacuum pump.Air inlet
Device 7 includes intake valve, and air inlet cushion pad is equipped in intake valve.
The method of physics de-bubble and chemical de-bubble is combined by the utility model, is avoided using only chemical defoaming mode,
Defrother is excessively used, it is difficult to clean up, be impacted to the subsequent handling of pcb board.Pcb board is placed into solution tank 6
Solvent in after, upper cover 2 is covered.Air extractor 1 is evacuated, and is changed the pressure in solution tank 6, is broken bubble in solution tank 6
Pressure balance, so that the bubble originally sticked on pcb board is floated on the surface of the water.For the bubble of liquid surface, due to direct and molten
Gas contact in liquid bath 6, when the air pressure in solution tank 6 reduces suddenly, the pressure balance of the bubble of liquid surface is serious
It destroys, the bubble on surface is made to rupture.Air extractor 1 need to only take out pressure in appropriate degree, its pressure change is made to reach
Certain value.Antifoaming agent medicinal cupping 5 is sent into antifoaming agent to the solution in solution tank 6, and bubble is made to be not easy to generate and deposit in the solution
It stays.The amount that antifoaming agent is added increases, and the decompression needed for 6 de-bubble of solution tank is smaller.Both defrother and decompression complement each other, jointly
Complete the work of de-bubble.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model structure, several modifications and improvements can also be made, these should also be considered as this
The protection domain of utility model, these all do not interfere with the effect and patent practicability of the utility model implementation.
