Abstract
The present invention relates to a kind of environment-friendly metal to remove liquid, includes the composition acetic acid 40~65% of following mass percent, nitric acid 10~30%, surfactant 1~2%, corrosion inhibiter 0.1~2%, brightener 0.1~1%, surplus is pure water.Surfactant is selected from nonionic surface active agent and anionic surfactant compounding mixture.Corrosion inhibiter is selected from ANN aluminium nitrate nonahydrate, silver nitrate, ferric sulfate, and compares mixture according to certain quality.This, which takes off golden liquid, has that environment-friendly, system harmfulness is small, and stability is high, service life length, and corrosion metal effect is good；While effectively corrosion metal is carried out, also stainless steel substrate layer will not be caused to corrode with golden membranous layer.
Description
Technical field
The present invention relates to a kind of environment-friendly metal to remove liquid, belongs to micron Electric Chemical Reagent technical field.
Background technology
The present invention is that a kind of environment-friendly metal removes liquid, and technical problem to be solved is to be directed to the existing skill of microelectronic industry
Art provides a kind of metal removal liquid, can effectively remove the metal levels such as aluminium between stainless steel substrate and golden film, nickel, chromium so that
Golden film is easy to be recovered, while on stainless steel and golden film without influence.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of de- golden liquid for above-mentioned prior art, can effectively be removed
The metal levels such as aluminium, nickel, chromium between stainless steel substrate and golden film, and for stainless steel, golden film without influence so that golden material is easy to
Recovery.
Technical scheme is used by the present invention solves the above problems：A kind of environment-friendly metal removes liquid, including following matter
Measure the composition of percentage
Acetic acid 40~65%,
Nitric acid 10~30%,
Surfactant 1~2%,
Corrosion inhibiter 0.1~2%,
Brightener 0.1~1%,
Surplus is pure water.
Preferably, the mass percent concentration of acetic acid raw material be 90~99.8%, the mass percent concentration of nitric acid material be
60~67%.
Preferably, surfactant is selected from nonionic surface active agent and anionic surfactant compounding mixing
Thing.Wherein, nonionic surfactant is OPEO.Anion surfactant polymerize for alkyl aryl ether
One or both of thing, Triton X-100.
Preferably, corrosion inhibiter is selected from ANN aluminium nitrate nonahydrate, silver nitrate, ferric sulfate, and compares mixture according to certain quality.Should
Corrosion inhibiter can be protected effectively in the case that golden film is not corrosion, the metal such as effective lateral erosion aluminium, nickel, chromium, so as to which gradually infiltration is rotten
Erosion forms hollow shape and causes golden film to come off, easily recovery.
Preferably, brightener is selected from Salzburg vitriol, effectively protects stainless base steel substrate.
Compared with prior art, the advantage of the invention is that：This, which takes off golden liquid, has that environment-friendly, system harmfulness is small, surely
Qualitative height, service life length, corrosion metal effect are good；, also will not be to stainless steel substrate while effectively corrosion metal is carried out
Layer causes to corrode with golden membranous layer.
