Description
Technical field
The present invention relates to the auxiliary agent field of printed circuit board, a kind of development effect good for printed circuit
Organic base developing agent of plate and preparation method thereof.
Background technology
Developing agent is one of auxiliary agent the most conventional in current printed circuit board, its by with exposure after sensitive material send out
Biochemical reaction, makes the configuration on circuit board display.Traditional developing agent generally uses alkalescence inorganic compound,
It mainly has sodium carbonate and potassium carbonate two kinds.And developing reaction usually multiple step format is carried out, as a example by sodium carbonate, sodium carbonate first exists
Hydrolysis occurring in water, generates sodium bicarbonate and sodium hydroxide, then sodium bicarbonate hydrolyzes further, generates the effective of development
The stable state mixture of composition carbonic acid and sodium hydroxide, carbonic acid and sodium hydroxide is sent out with the organic carboxyl acid in wire mark circuit dry film again
Raw neutralize reaction, generate the carboxylic acid sodium salt with solubility, thus realize manifesting of configuration in dry film.But, whole
During developing reaction, owing to there is calcium ion and magnesium ion in water, the carbonic acid in mixture is meeting and calcium when developing reaction
Ion and magnesium ion generation chemical reaction, generate calcium carbonate and the magnesium carbonate being insoluble in water.Above-claimed cpd meeting and carboxylic acid sodium salt
Forming two-phase mixture, and stick on the plate face of circuit board, development is unclear, circuit shows muddy to cause the circuit of circuit board to occur
The defects such as turbid, circuit glacing flatness is extremely low.
Additionally, calcium carbonate and magnesium carbonate along with current are by groove cylinder, and can stick to be formed on the inner surface of groove cylinder incrustation scale,
Groove cylinder is made to need frequent clean in use.It is true that owing to the carbonate in carbonate is hydrophilic group, and it occurs with water
Hydrolysis be undertaken in two steps, so developing agent can produce after having developed the most heterogeneous biphase mixed solution.On
State mixed phase solution and can stick on plate face with the most undissolved dry film fragment, organic compound and little micelle, make circuit it
Between occur short circuit, had a strong impact on the printing quality of circuit board.Therefore, a kind of development that can solve the problems referred to above how is researched and developed
Agent, is one significant technology issues of current printed circuit board industry.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of development is clear, be easy to cleaning and the use longevity
The organic base developing agent for printed circuit board that life is long.
Another object of the present invention is to provide a kind of technique simply to prepare the above-mentioned organic base for printed circuit board
The method of developing agent.
The goal of the invention of the present invention is achieved in that a kind of organic base developing agent for printed circuit board, its feature
Being: described organic base developing agent includes water, monoethanolamine and triethanolamine, said components is calculated by mass fraction and is respectively as follows: water
100 parts, monoethanolamine 1-6 part, triethanolamine 1-4 part.
Furtherly, water is deionized water.
Furtherly, monoethanolamine content is 1 part, and triethanolamine content is 1 part.

Furtherly, monoethanolamine content is 3 parts, and triethanolamine content is 2 parts.
Furtherly, monoethanolamine content is 4 parts, and triethanolamine content is 3 parts.
Furtherly, monoethanolamine content is 5 parts, and triethanolamine content is 4 parts.
The present invention also provides for a kind of method preparing the above-mentioned organic base developing agent for printed circuit board, the step of the method
Rapid as follows:
A: weigh corresponding raw material for standby according to said ratio；
B: under normal temperature and pressure state, is sequentially added into water, monoethanolamine and triethanolamine in the container with blender；
C: maintaining temperature in container is room temperature, and open blender stirring and be dispersed in monoethanolamine and triethanolamine
In water, for the organic base developing agent of printed circuit board.
The organic base developing agent for printed circuit board of prior art is improved by the present invention, and its advantage is as follows:
1, in the organic base developing agent of the present invention, current inorganic alkaline system is replaced with organic basic system.By drawing
Enter, with calcium ion in water and magnesium ion, the organic group of chemical reaction does not occur, thoroughly stopped developing agent and calcium during developing reaction
Ion and magnesium ion generation side reaction.Organic basic system can fundamentally solve to be insoluble in the calcium salt of water and magnesium salt when development
Stick to the problem on plate body, it is to avoid the defect that circuit display muddiness occurs when development in plate body, circuit glacing flatness is low, thus greatly
The stability of development and reliability when width improves printed circuit board.Further, since organic basic system will not be with the calcium in water
Ion and magnesium ion react, thus will not form incrustation scale on the inwall of cylinder groove when liquid transmits, and are truly realized aobvious
The spatter property processing of shadow operation.Simultaneously as the density of organic basic system is less than water, water can be floated on adding said components in man-hour
Upper strata, make organic basic system preferentially can discharge from the overfall of cylinder groove, both ensured the cleannes of liquid in cylinder groove, the most just
In the recovery of organic basic system, thus effectively reducing the wash number of cylinder groove, developing procedure is greatly improved adds work efficiency
Rate, and reduce liquid waste processing difficulty in cylinder groove.
2, in the organic base developing agent of the present invention, organic basic system self has hydrophilic group hydroxyl and hydrophobic group hydrocarbon
Base.Dry film impurity can effectively be dissolved by this organic basic system, and constitutes single phase soln of separation configuration with water.Due to aobvious
Shadow agent utilizes Organic substance as dissolving media, plays the similar effect of mixing, thus organic base developing agent can be from root between its to dry film
Change developer solution in basis and form the present situation of biphase even multi-phase solution after completion of the reaction, and make dry film fill in a developer
Point dissolve, it is to avoid the precipitation in the solution such as micelle, dry film fragment also sticks on the plate body of circuit board, thus effectively reduces line
The phenomenon of short circuit occurs because of stuck foreign matter between road.Additionally, utilize the similar principle that mixes, dry film is had extremely strong by developing agent
Solute effect, thus improve the dissolubility that dry film is dissolved by developing agent, solution load is high, service life is long to make developing agent have
Advantage.
3, in the organic base developing agent of the present invention, have employed organic dissolution system, and this dissolution system will not with in water
Calcium ion and magnesium ion react and form water-fast precipitate.Utilize and occur between above-mentioned dissolution system and circuit board to show
Shadow reacts, and is effectively reduced the short circuit between intensive circuit.Owing to the circuit after above-mentioned developing reaction shows very clearly, and
The glacing flatness of circuit can be improved, secondary pollution will not be produced in the circuit board simultaneously, thus this developing reaction can effectively reduce
Residual copper fraction defective on circuit board and impedance aberration rate, thus improve the printing quality of circuit board.
4, the organic base developing agent of the present invention uses the mixing method that mixes to be prepared.First, the mixing method that mixes can improve aobvious
The uniformity of shadow agent solution so that it is have stable chemical reactivity.Secondly, the process of the mixing method that mixes is very simple, energy
Effectively reduce the preparation difficulty of developing agent, reduce its preparation time, to adapt to quickly carrying out of printed circuit board.
