For clearly statement " being originally used for the pen of dress correction fluid ", this specification provides concrete introduction.Correction fluid, is also opaquing fluid, is also correction pen, this is a kind of very common cultural goods, and it is pressed against the word surface needing amendment, will flow out the liquid of white, this liquid quickly dries, it is possible to hide the word wrongly write, and can at its dry other writing words in surface.Used in the present invention is not use the liquid within correction fluid, but utilizes the pen taking up correction fluid (also to be understood as container, device.).
By the way, inventor attempts using correction fluid directly as the liquid covering metal forming in copper-clad plate, find: covering power is not enough, liquor ferri trichloridi is readily permeable in the place that cover layer is relatively thin, and, correction fluid after solidification (become dry, hardening) has and a lot remains in copper-clad plate, is difficult to remove.
A kind of in copper-clad plate cover metal forming method, the steps include:
The first step, configuration covers the liquid of metal forming, and collocation method is:
A, adding parts by weight in the anhydrous alcohol that parts by weight are 50 is the paint of 20, and mix homogeneously,
B, adding parts by weight in mixture described in a step is the formic acid of 4, and mix homogeneously,

Copper-clad plate covers a kind of method of metal forming, the steps include:
The first step, configuration covers the liquid of metal forming, and collocation method is:
A, adding parts by weight in the anhydrous alcohol that parts by weight are 50 is the paint of 20, and mix homogeneously,
B, adding parts by weight in mixture described in the first step is the formic acid of 4, and mix homogeneously,
C, adding parts by weight in the mixture described in second step is the liquid paraffin of 5, and mix homogeneously.
Second step, injects the liquid of first step configuration in the pen being originally used for dress correction fluid, prepares the pen covering metal forming for copper-clad plate,
3rd step, describes in copper-clad plate with the pen described in second step, and is depicted in above the metal forming that copper-clad plate needs to retain.Inventor also attempts using the mixture of anhydrous alcohol and paint (to refer to: adding parts by weight in the anhydrous alcohol that parts by weight are 50 is the paint of 20, and mix homogeneously,) to cover metal forming for copper-clad plate, discovery has the following advantages: 1, covering power is very strong, 2, it is not necessary to covering liquid (refers to the mixture of paint and anhydrous alcohol) and is completely dried up just can putting in liquor ferri trichloridi and corrodes.Find there is following defect: not easily clean up simultaneously.
For a lot of people, the organic solvent being readily obtained is anhydrous alcohol, moreover covering liquid just has anhydrous alcohol and paint, so, clean the paint become dry with anhydrous alcohol, be the method that it is readily conceivable that, test shows: 1, if paint is enough hardening (being commonly called as exsiccation) not, when cleaning, paint easily pollutes hands, container and other environment.2, if paint enough hardening, when cleaning, it is necessary to a large amount of anhydrous alcohols, and, it is spread across on ground, trace can be left, be difficult to clean up.
The composite fluid of present disclosure, (note: this composite fluid is adopted and prepared with the following method:
The first step, adding parts by weight in the anhydrous alcohol that parts by weight are 50 is the paint of 20, and mix homogeneously,
Second step, adding parts by weight in mixture described in the first step is the formic acid of 4, and mix homogeneously,
3rd step, adding parts by weight in the mixture described in second step is the liquid paraffin of 5, and mix homogeneously.) have the advantage that
Advantage 1, covering power is strong, and liquor ferri trichloridi will not pervious cover layer.Inventor is in the environment of room temperature 25 degrees Celsius, describe to organize lines on copper-clad plate surface with it more, brushing amount (may also be used for characterizing brushing thickness) for every square metre 80 grams to 100 grams, place 10 minutes after description---15 minutes, it is then placed in the saturated liquor ferri trichloridi of 30 degrees Celsius and soaks 20 minutes, then cover layer is removed, it has been found that metal forming (Copper Foil) upper surface that coating cap rock hides is not etched.
Need that explains to have: copper-clad plate upper surface is not corroded, illustrate that cover layer has good covering power, but, the side not representing copper-clad plate metal forming is not etched, various equivalent modifications should be known: copper-clad plate is put in liquor ferri trichloridi, should pass through to rock the modes such as copper-clad plate, allow ferric chloride corrode the metal forming not obtaining covering as early as possible, in order to avoid the side of the further attack metal paper tinsel of liquor ferri trichloridi.Various equivalent modifications is also it is to be understood that circuit is affected less by the side that ferric chloride corrodes copper-clad plate metal forming, because this processing method is used for the circuit board that processing line is wider, circuit side is etched, and is equal to the narrowed width of circuit a bit.In sum, because erosion time is not long, and widths affect is less, and the impact that metal forming side is etched is negligible.
Also need to the covered thickness explained.Inventor is not directly measured the thickness of covering, because the thickness smearing liquid is difficult to directly measure.
Advantage 2, just can remove cover layer, and be prone to remove totally without solvent clean cover layer.In the environment that room temperature is 25 degrees Celsius, lasting 10 minutes to 20 minutes from being applied to immersion liquor ferri trichloridi, the time being immersed in liquor ferri trichloridi lasts about 15 minutes, after taking out from liquor ferri trichloridi, cover layer is softer and forms mantle, scrapes off gently with pocket knife and just can remove totally.Or: after taking out copper-clad plate from liquor ferri trichloridi, being shelved on normal temperature environment (about 25 degrees Celsius) and last about 50 minutes, cover layer can form film, pry open cover layer with pocket knife one jiao, tears with hands and cover layer just can be completely exfoliated.Or: after taking out copper-clad plate from liquor ferri trichloridi, it is shelved on normal temperature environment (about 25 degrees Celsius) and lasts about 80 minutes, cover layer can form harder film, is pasted onto cover surface with adhesive tape, presses adhesive tape (pressure applied is every square centimeter and applies pressure 10----20 newton) with hands, adhesive tape and cover layer is made to fit tightly, then, tear adhesive tape, now, adhesive tape has bonded cover layer, overburden stripping copper-clad plate.And, after taking out copper-clad plate from liquor ferri trichloridi, it is shelved on after normal temperature environment (about 25 degrees Celsius) lasts three days, still any one method in following two method can be adopted to peel off cover layer: 1, first pry open cover layer with pocket knife one jiao, then tear, with hands, the film that cover layer is formed, 2, peel off, with adhesive tape, the film that cover layer is formed.The adhesive tape that inventor adopts is " capable " board adhesive tape, and its trade name is: 30029 stationery adhesive tapes, and width is 12mm, and 30029 is the adhesive tape producer numbering to these commodity.
Inventor only with anhydrous alcohol and paint mixing, adopts multiple proportioning, and the cover layer formed all can not be removed by the method described in passage or remove clean.And find: the cover layer being only mixed with anhydrous alcohol and paint is extremely difficult to peeling.
The liquid paraffin that inventor adopts is: the liquid paraffin that trade name is " liquid paraffin " that Guangdong, Taishan City emigrant's reagent plastics company limited produces, lot number: 20121001, and label are marked with " chemical pure " printed words.
Also need to having of explanation: poor adhesive force and good sealing effect not contradiction, for instance: adhesive tape sealing effectiveness is fine, but, poor adhesive force-----can tear off with hands.
It can further be stated that: poor adhesive force does not represent can self falling, for instance: adhesive tape poor adhesive force, but, up-to-standard adhesive tape is pasted onto smooth finish surface will not self falling.
Only paint and anhydrous alcohol are encased in the pen being originally used for dress correction fluid, it is easy to following three kinds of situations occurring: 1, when shared by anhydrous alcohol, weight ratio is excessive, the wayward thickness of trace drawn, because mobility is excellent.2, when shared by anhydrous alcohol, weight ratio is too small, not easily flow out from the pen being originally used for dress correction fluid.3, even if the proportioning of careful debugging paint and anhydrous alcohol, place under normal temperature laboratory and exceed half a year, also nib is easily blocked---the mouth of-i.e. blocking liquid outflow, further, this blockage is difficult to overcome, once block, blocking is difficult to eliminate, and namely uses anhydrous alcohol to soak nib and also is difficult to eliminate blocking.
But, presently disclosed composite fluid is encased in the pen being originally used for dress correction fluid, overcome above-mentioned three kinds of deficiencies, have the advantage that mobility is suitable for, it is easy to control trace (it can be appreciated that person's handwriting) thickness, also liquid is easily allowed to flow out from nib, place under normal temperature laboratory and exceed half a year, although the phenomenon of blocking nib also can occur once in a while, but, the housing at nib place is peeled off, it is possible to normally use by fingernail.
Only paint and anhydrous alcohol being encased in the pen being originally used for dress correction fluid, once there is nib blocking, the housing that nib is formed cannot be deducted by fingernail, because the housing adhesive force formed is too strong.
The pen being originally used for dress correction fluid is used to irrigate this liquid of the present invention, it is also an advantage that: there is a spherical weight inside this pen, this bead agitated liquid can be allowed by the mode of hand-held concussion before using, play the effect of mix homogeneously.
The metal level that copper-clad plate surface of the present invention covers is Copper Foil.
The liquid of present disclosure is used for copper-clad plate, is had the benefit that and is prone to remove clean cover layer.
