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 take off film liquid art, refer in particular to a kind of take off film effective, take off the film time short take off film liquid.
Background technology
Take off film and be and utilize alkalescence to take off film liquid the resin neutralization containing acidic group, thus out dissolved, make dry film depart from copper face, often can use and take off film liquid in the making of electronic product circuit with in the middle of producing.
At present general way is to adopt sodium hydroxide, common sodium hydroxide in the time taking off film, because of dry film blocked up (80 μ m), liquid medicine attack corrode dry film ability a little less than, need 20 minutes above dry film can being taken off totally, make production efficiency reduction.And, invade for a long time bubble in sodium hydroxide solution taking off in membrane process because of slice, thin piece, copper face easily occurs that oxygenant takes off film and is difficult for, thereby causes etching unclean.
Summary of the invention
In view of this, the present invention is directed to the disappearance of prior art existence, its main purpose is to provide one and takes off film liquid, its can effectively solve existing employing sodium hydroxide take off film exist take off the film time long, take off the sordid problem of film.
For achieving the above object, the present invention adopts following technical scheme:
One takes off film liquid, is made up of the raw material of following weight proportion:
Potassium hydroxide 80%～85%;
Trolamine 8.5%～15%;
Polyoxyethylene nonylphenol ether 21 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 obvious advantage and beneficial effect, particularly, and as shown from the above technical solution:
What adopt the present invention formula takes off film liquid, and it takes off film speed and takes off film ability is nearly five times of sodium hydroxide, thereby has greatly improved production efficiency, and has effectively improved while taking off film copper face and taken off the problems such as film is not clean.
