Abstract
The invention relates to an organic film removing agent, which is characterized by consisting of the following components in percentage by weight: 20 to 50 percent of organic alkali, 0.1 to 1.0 percent of chloride, 1.0 to 5.0 percent of sorbitol, 0.1 to 1.0 percent of copper corrosion inhibitor and 45 to 74 percent of deionized water. The organic film removing agent is suitable for a negative dry film used for alkali solution development, and the main component of the dry film is polymer with carboxyl. In the organic film removing agent of the invention, the organic alkali can react with the polymer with the carboxyl in the dry film to ensure that a large dry film is broken into small blocks; the chloride can promote the quick separation of an interface between the dry film and a copper plated layer; the sorbitol enables the organic film removing agent to reach the inner part of the dry film quickly; and the organic alkali, the chloride and the sorbitol are cooperated with one another to ensure that the organic film removing agent has high performance of quickly removing a 'clamped film'-shaped dry film from a copper substrate, high film removing efficiency and good film removing effect. The organic film removing agent has the advantages of low toxicity, safe use and easy treatment of waste solution.
Description
Technical field
The present invention relates to a kind of in the line pattern transfer process of printed circuit board, being used for from organic film that moves back of substrate stripping dry film.
Background technology
At present, make printed circuit board when (being called for short PCB), in the circuit figure transfer, dry film is one of important " imaging " technology." imaging " dry film afterwards need be with moving back film with its removal (promptly moving back film), to carry out next step etch process.In graphic plating technology because graphical distribution is inhomogeneous, the plate subregion after plating, the thickness that copper coating can occur near or exceed the situation of the thickness of dry film, make dry film be clamped by copper coating, be commonly called as " folder film ".Nipped dry film moves back film exchange difficulty with to move back the film surface of contact little, and it is unclean to cause moving back film, and short circuit appears in circuit easily after the etching.
At the situation of " folder film ", it is to prolong to move back the time of membrane operations that routine is moved back membrane technology, or repeatedly does over again and move back membrane operations again, moves back membrane efficiency but do so seriously to reduce.Move back membrane efficiency in order to improve, the another kind of existing membrane technology that moves back is to add auxiliary agent such as butyl cellosolve when moving back film in moving back film in addition, moves back the solubility property of film to dry film with improvement, but the butyl cellosolve higher material that is toxicity, use dangerously, and the useless film liquid intractability that moves back is big.
Summary of the invention
Technical matters to be solved by this invention provides a kind of organic film that moves back that is used to strip dry film, and this organic film that moves back has premium properties that can peel off " folder film " shape dry film from the copper base material, move back the membrane efficiency height, and toxicity is low, and is safe in utilization.The technical scheme that adopts is as follows:
A kind of organic film that moves back is characterized in that being made up of the component of following weight number percent:
Organic base 20-50%;
Villaumite 0.1-1.0%;
Sorbierite 1.0-5.0%;
Copper inhibitor 0.1-1.0%;
Deionized water 45-74%.
Above-mentioned organic base is to have chemical general formula R-NH
2Organic amine in a kind of or wherein multiple combination, R can be alkyl, hydroxy alkyl or aminoalkyl, for example: isopropylamine, monoethyl amine, diethylamine, triethylamine, a n-propylamine, a n-butylamine, di-n-butylamine, tri-n-butylamine, sec-butylamine, monoethanolamine, diethanolamine, triethanolamine, diglycolamine, tert-butylamine, 1,4-butanediamine, 1,2-propane diamine, 1,3-propane diamine etc.
Above-mentioned villaumite can be a kind of or wherein multiple combination in sodium chloride, potassium chloride and the magnesium chloride.
Above-mentioned copper inhibitor can be protected copper face (comprising the surface of copper base material and the surface of copper coating), reduces the corrosion of the organic base of high concentration to copper.Above-mentioned copper inhibitor can be a kind of or wherein multiple potpourri in the derivant (as 5-methylbenzotrazole, 5-carboxyl benzotriazole, 4-carboxyl benzotriazole, I-hydroxybenzotriazole), imidazolines (as 2-oleic imidazolinone, naphthenic acid imidazoline), thiazole compound (as thiazolamine, 2-mercaptobenzothiazole), quaternary ammonium salt (as hexadecyltrimethylammonium chloride, cetyl trimethyl ammonium bromide) of benzotriazole, benzotriazole.Preferred above-mentioned copper inhibitor is the derivant of benzotriazole or benzotriazole.
Above-mentioned organic film that moves back can adopt following method manufacturing: be equipped with earlier organic base, villaumite, sorbierite, copper inhibitor and deionized water in proportion; Then organic base, villaumite, sorbierite and deionized water are mixed under room temperature (being generally 20-25 ℃), obtain mixed solution; Again copper inhibitor is joined in the above-mentioned mixed solution, and mix, obtain organic film that moves back.
Above-mentioned organic film that moves back can be according to moving back the film needs when using, and water dilutes, and water consumption is generally organic 4-9 that moves back film weight doubly.
Organic film that moves back of the present invention is suitable for the negativity dry film that alkalies develops, and the principal ingredient of dry film is the polymkeric substance of band carboxyl.Organic moving back in the film of the present invention, organic base can with dry film in the band carboxyl polymer reaction, form water miscible polymkeric substance, make the dry film of bulk be fragmented into fritter; Villaumite can impel dry film to separate fast with the interface between the copper coating; Sorbierite has good effect of impregnation may to dry film, makes organic film that moves back can arrive dry film inside fast; Organic base, villaumite and sorbierite three cooperate, and make organic film that moves back of the present invention have the premium properties of peeling off " folder film " shape dry film from the copper base material fast, move back the membrane efficiency height, and it is effective to move back film.Organic film that moves back of the present invention does not contain the higher material of toxicity, and toxicity is low, and is safe in utilization, and waste liquid is handled easily.
