Abstract
The invention discloses a film-stripping liquid. The film-stripping liquid comprises the following raw materials in percentage by weight: 80%-85% of potassium hydroxide, 8.5%-15% of triethanolamine, 1%-2% of emulsifier OP21, 0.3%-0.5% of ethylene glycol butyl ether, 2%-3% of methanol and 0.5%-1% of acetone. By virtue of the film-stripping liquid prepared from the formula disclosed by the invention, the film-stripping speed and the film-stripping capability are nearly five times of those of sodium hydroxide so that the production efficiency is greatly improved and the problems that the copper surface is not clean and the stripped film is not complete when the film stripping is carried out are effectively solved.
Description
Technical field
The present invention relates to taking off film liquid art, refer in particular to a kind of take off that film effect is good, to take off the film time short takes off film liquid.
Background technology
Taking off film is to take off film liquid using alkalescence the resin containing acidic group is neutralized, thus being dissolved out, makes dry film depart from copper face,
Often using to taking off film liquid in the making of electronic product circuit and in the middle of producing.
At present widespread practice is to adopt NaOH, common NaOH when taking off film, because of dry film blocked up (80 μm),
Liquid medicine attack erosion dry film ability is weaker, needs to take off clean so that production efficiency reduces by dry film in more than 20 minutes.And
And, because slice, thin piece invades bubble for a long time in sodium hydroxide solution in taking off membrane process, easily oxidant and takes off film being difficult in copper face, from
And lead to etching unclean.
Content of the invention
In view of this, the present invention is directed to the disappearance of prior art presence, and its main purpose is to provide one kind to take off film liquid, its energy
Effectively solving existing using NaOH take off film exist take off film time length, take off the sordid problem of film.
For achieving the above object, the present invention is using following technical scheme:
One kind takes off film liquid, is made up of the raw material of following weight proportion:
Potassium hydroxide 80%～85%；
Triethanolamine 8.5%～15%；
Emulsifying agent op21 1%～2%；
Ethylene glycol monobutyl ether 0.3%～0.5%；
Methyl alcohol 2%～3%；
Acetone 0.5%～1%.
The present invention compared with prior art has clear advantage and beneficial effect, specifically, by technique scheme
Understand:
Film liquid taken off using inventive formulation, it takes off film speed and takes off nearly five times that film ability is NaOH, thus
Substantially increase production efficiency, and effectively improve when taking off film copper face and take off film net the problems such as.
Specific embodiment
The open one kind of the present invention takes off film liquid, is made up of the raw material of following weight proportion:
Potassium hydroxide 80%～85%；
Triethanolamine 8.5%～15%；
