Abstract
The invention discloses a kind of welding resistance character strippers, raw material including following mass percent: sodium hydroxide/potassium hydroxide: 5-7%, one of ethanol amine, diethanol amine, triethanolamine or a variety of: 4-10%, tertiary sodium phosphate: 1.5-2.5%, lauryl sodium sulfate 1-2%, surplus are water；Preparation method is to be added to the water above-mentioned each component, is sufficiently mixed uniformly to get welding resistance character stripper.Welding resistance character stripper of the present invention reduces the basicity that ink strips, temperature and strips the time, reduces energy consumption, energy saving, and solves that aperture penetration power is poor, and substrate ink strips the problem that glass line appears.The copper face of printed wiring board, golden face are not attacked, ink is improved and strips yields to be done over again, reduce the production cost of printed wiring board.
Description
Technical field
The present invention relates to wiring board detergent field, in particular to a kind of welding resistance character stripper.
Background technique
Printed wiring board solder mask is to prevent that short circuit occurs between route or pad in welding, and on printed wiring board
One layer of solder mask of silk-screen, legend ink then on printed wiring board on silk-screen component the model (symbol including component
Number), convenient for the assembly of component.Since ink is by being screen-printed on wiring board, especially solder mask must also be pre- solid
Change silk-screen another side again, then carry out precuring, after precuring after film exposure development, then is solidified, process is tedious, because of silk
Printed network version, film exposure positioning, film harmomegathus, exposure quality, development include having enough to meet the need the factors such as special to easily cause welding resistance character
The quality of ink is bad, needs to strip the printing of welding resistance legend ink and is up to 5-10%.
Traditional printed wiring board factory generallys use the immersion of sodium hydroxide high temperature, and defect is: temperature is (90 DEG C -95 high
DEG C), the time is long (4 hours or so), and operation is dangerous, and aperture penetration power is poor.The time of so high basicity, temperature and length, easily
Printed wiring board copper face is caused to corrode, golden face discoloration, especially ripple appears (non-line section).Since single sodium hydroxide is shelled
Except welding resistance legend ink plate gives up, rate is high, and general substrate is 25-30%, can be in any more production cost.With printed wiring board electricity
The development of sub-industry, the more and more common use of Halogen substrate, ink strip difficulty and also increasingly improve, and need efficient, high quality oils
Black stripper.Therefore, there is an urgent need to a kind of welding resistance character strippers, so that stripping on rear printed wiring board without welding resistance legend ink
Residual will not attack printed wiring board substrate copper and golden face, not will cause ripple and appear, highly effective and safe.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of welding resistance character strippers.
