Description
Technical field
The present invention relates to electroplating pretreatment process, more particularly to a kind of acid deoiling agent for preventing copper on hanger and
Its preparation and application.
Background technology
Pattern transfer process is arrived involved in the wiring board technological process of production, the material used in this process is ink/dry film,
Containing there are many macromolecular organic compounds in composition.More or less contain some residuals in developed rear board and hole, therefore
It is cleaned with degreaser in the plating copper and tin process in downstream, so that plating coating is smoothed out.
Due to being acidic materials in the material ink and dry film used in pattern transfer, the formula of degreaser must be selected
Acid main body, but the tin by subsequently being plated is amphoteric metal, can dissolve tin under acid condition.The contact point of graphic plating hanger
Plating meeting plated with copper and tin repeatedly, the tin through acid deoiling agent dissolving is since gravity can flow to plate face, on resistance coating again
Form conductive layer, plating on coating hindered during follow-up plating and is covered with copper and tin, causes circuit difficult forming, it is necessary to hanger into
Row cleaning copper and tin, can just be reused, and the complexity of production process is not only increased, and improve production cost reduction life
Produce efficiency.
Invention content
Technical problem to be solved by the invention is to provide a kind of acid deoiling agent preventing copper on hanger, the acidity
Degreaser can prevent the contact point of Electroplating Rack repeatedly plating when plated with copper and tin, when solving using existing degreaser, through acid
Property degreaser dissolving tin plate face can be flowed to due to gravity, form conductive layer, follow-up plating process again on resistance coating
The problem of plating is covered with copper and tin, causes circuit difficult forming on middle resistance coating, avoids also needing to carry out cleaning extension after having plated every time
Frame goes the trouble of copper removal and tin, reduces production stage, provides production efficiency and reduces production cost.The present invention also provides this can
Prevent the method for preparation and use of the acid deoiling agent of copper on hanger.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of acid deoiling agent preventing copper on hanger, by following substance proportioning form, every liter containing 5~10g inorganic acids,
The anti-tin lytic agent of 0.05~5g surfactants, 1~10g inorganic salts, 1~5g, surplus is deionized water, the anti-tin lytic agent
For pyrazoles or pyrazole compound.
In the present invention, the inorganic acid be sulfuric acid, phosphoric acid, hydrochloric acid at least two.
In the present invention, the surfactant is Op-10 (alkyl phenol polyoxyethylene ether), Np-9 (alkyl phenol polyoxy second
Alkene (9) ether), Np-30 (nonylpenol polyoxyethyene ether (30)), Np-10 (nonylphenol polyoxyethylene ether (10)) it is any.
In the present invention, the inorganic salts be tertiary sodium phosphate, silicate it is any.The silicate is for sodium metasilicate or partially
Sodium metasilicate.
In the present invention, the pyrazole compound be nitropyrazole, Isosorbide-5-Nitrae-dimethyl pyrazole, 3,5- dimethyl pyrazoles,
At least one of 1,4- dimethyl pyrazole tertiary sodium phosphates.
A kind of preparation method of the acid deoiling agent, includes the following steps：Inorganic acid is added in deionized water, it is cooling
To at 40 DEG C；Surfactant, inorganic salts, anti-tin lytic agent are sequentially added, latter reagent is added every time and is being completely dissolved
It after former reagent, is uniformly mixed, obtains acid deoiling agent.Preparation process can be accelerated molten by modes such as stirring or ultrasounds
Solution.
A kind of application method of the acid deoiling agent, it is clear that by acid deoiling agent, 5% concentration, which is diluted with water, by volume
Clean dose, required oil removing matrix is impregnated at least 5min by detergent, taking-up, which cleans up, can carry out lower step processing.
The present invention has the advantages that：The acid deoiling agent can prevent the contact point of Electroplating Rack repeatedly plating when plate
Upper copper and tin, when solving using existing degreaser, the tin through acid deoiling agent dissolving can flow to plate face due to gravity,
Conductive layer is formd on resistance coating again, plating on coating is hindered during follow-up plating and is covered with copper and tin, causes circuit difficult forming
Problem avoids also needing to carry out the trouble that cleaning hanger removes copper removal and tin every time after having plated, reduces production stage, use the acidity
The hanger of degreaser can reuse 5 times or more without cleaning, provide production efficiency and reduce production cost.Use the acidity
Degreaser, the not upper copper of Electroplating Rack, can save valuable metals resources waste, such as copper, tin；Improve product qualification rate；It can use less
Or different nitric acid nitre hangers, the use of dangerous strong acid is reduced, the discharge of nitrogen dioxide is reduced, there is safety, to environment friend
It is good, environmental protection.
