Description

Automatic deposition emulsion and the method for the metal surface being carried out selective protection with this emulsion
This is a part continuation application, be No. 451658 applications that 1989.12.15 is submitted to by people such as Browne, and 1989.12.15 is by the part continuation of No. 451680 applications of people such as Elzufon submission.
The present invention comes the metal surface about automatic deposition emulsion and with this emulsion, particularly to those surfaces that corroded by caustic solution, carries out selectively applied method when making the circuit diagram of printed circuit board.
All on the metal surface, be coated with coating in many cases, make the surface avoid the destruction of corrosive atmosphere.For example, the coating of body of a motor car base plate can be avoided the corrosion of road surface salt thing to vehicle body.Coating steamer hull is avoided the corrosion of ocean surface air with the protection hull.In above-mentioned example, a kind of polymer coating in whole surface of matrix perhaps makes its complete polymerization with giving polymers after being coated on the matrix again.
In addition, some zone is also wished to protect selectively in the metal surface.For example the circuit diagram of printed circuit board (PCB) is when processing is handled, optionally protective money metal surface situation about coming to this.In these cases, only giving some selected earlier zone on the metal surface covers with polymer film.
Say exactly, the making of printed circuit, in gluing, imaging, development and etching process, can be with in two kinds of photoetching agent systems any.First kind of system is to be coated with substrate or metal surface with a kind of negativity photoetching agent, and this photoetching agent exposes and polymerization under actinic radiation.Second kind of system is to be coated with substrate or metal surface with positivity photoetching agent, and this photoetching agent becomes after actinic radiation exposure and to dissolve in developer solution.
Any photoetching agent as long as be coated onto after surperficial the going up, will will should expose under actinic radiation on the surface.When using negativity photoetching agent, expose by the photographic negative that has required circuit image in this surface.As a result, photopolymerization takes place and it is separated than indissoluble in developer solution in exposed to the sun through the radiation photoetching agent position of light.Like this, in development phase, those are covered and the photoetching agent that is not subjected to the radiation position does not have polymerization basically, they are dissolved to the undissolved appropriate solvent in photopolymerization position takes place with a kind of.This operation is called development, because it shows the circuit image by the metal surface at topped some position not.After the development, not topped corrosion is formed printed circuit.Photopolymerisable photoetching agent is removed with a kind of solvent by chemical method then, stay the metal surface that is not corroded and form circuitous pattern.
When with positivity photoetching agent, expose by the positivity image of required circuit in the surface that was coated with.The coating at this exposure position thereby be soluble, and then in developer solution, be removed.The same practice during with use negativity photoetching agent stays the positivity image that not topped metal surface stays its corrosion in required circuit during development.
The photoetching agent has become important instrument when making has the wiring board of electroplating ventilating hole.Along with the increase day by day of the printed circuit board of making two-sided conduction, the application in this hole is also increasing.The conductive surface that increases has improved the capacity of wiring board.
Above the said dual platen laminated plate material normally formed by copper/epoxy resin/copper make.Each of laminate all has the wiring diagram after corrosion above the face copper.The two sides of plate is according to the requirement of mask body circuit on it, and the through hole by aperture or plating makes the two sides connect energising.These holes are called " component hole " or " through hole " in this field.These through holes are nonconducting when beginning to be drilled to the hole, because the epoxy layer of an insulation of sandwich.Therefore, necessary copper facing makes between the copper of plate two sides and can conduct electricity in the hole, and this copper facing can be taked the electroless copper sedimentation, forms a kind of electroplating ventilating hole (PTH) therefrom.Another kind of PTH is that copper electrowinning forms again in the above after original chemical depositing copper.See Norman.S.Einarson, printed circuit technique (publishing 1977 by Printed CircuitTechnology); Fisher, G.L; Sonnenberg, W ﹠ Bernards, R.; " plating in high length-diameter ratio hole " P.e.c. manufacturing, Vol.12, No.4(1989.4) pp 39-66; D ' Ambrisi, people such as J.J., " small diameter bore electroless plating ", part II, P.e.c. manufacturing, Vol 12.No.8(1989.8) pp.30-42.
The difficulty of circuit board manufacturing at first is on those copper-plated apertures.After having bored hole and copper facing, this laminate can make the copper coating in the hole be damaged through corrosion treatment.For this reason, developed the method in various different protection copper facing hole in the prior art.
It is 1. with paraffin plug plug-hole that two kinds of guard methods are arranged, and 2. with dry liquid photoetching film the hole is hidden.Yet the paraffin plug is had any problem in operation, because will remove them into problem when no longer needing to fill in, in addition, covering method has been obtained very ten-strike at present, but its use also has some troublesome problem.
Covering method is to protect copper-plated hole with the dry film that contains the photopolymerization sheet.Exposed and polymerization with ultraviolet radiation in diaphragm zone topped and the protection hole.In treatment process subsequently, leave the copper facing hole that is covered by this " tent " on this wiring board.These tents are removed with appropriate solvent later.
It must be extremely thin requiring the used topped thing that protectiveness, photopolymerization are arranged as the light imaging that those skilled in the art will appreciate that circuit on technology.Therefore, when using covering method, this polymerisable tent is very thin.Make it become very crisp, be worn easily, fracture or " puncture " owing to thin.In case the crack occurs, then solvent or mordant are entered with regard to porous, contact with the copper that on the through hole limit, is deposited, thereby being coupled to each other between this two sides copper sheet is damaged, same problem also can take place when topped dry film irrelevantly, thus make corrosive liquid and developer solution be penetrated into film below.
Method with hiding the hole except film rupture, also can cause the surface of wiring board to form " annular ring ", or ridge.The formation of these circles be owing to the diameter that requires tent must be greater than the aperture so that make tent have attachment point to play protective effect to the hole.These circles or ridge form in the corrosion treatment process, because after the corrosion, this tent has not only been protected the coating of aperture the inside, and have protected around the aperture annular section on the metal surface.
But when when less wiring board and higher density circuit direction develop, these annular rings have just become problem.For example, along with dwindling of wiring board, has also just reduced in the space that these circles can account on the plate face.Therefore, surface area that can the adhesion tent will reduce.And along with design line pattern onboard is more and more, some big annular rings have also just more and more become the obstacle of design.For example the fine line circuitry of many runs parallel and each wiring diagram all require situation about being connected with the another side of circuit board.Such situation requires a hole, if but the annular ring in this hole is too big, and other wiring diagram then must leave this hole in order to avoid short circuit.Therefore, avoid designed lines around circle, be advisable so that they are gathered together.
In addition, it has been generally acknowledged that resins for universal use/photochemical functional agent composition of finding can dissolve less characteristic in common photoetching agent.On the other hand, the liquid and the desciccator diaphragm photoetching agent that are suitable for do not reach the max cap. that forms better characteristic with high yield, it has been generally acknowledged that its defective is less than those defectives with the coating process gained film of general fluid and desciccator diaphragm photoetching agent with thin film.But; the coating process that some other is known; for example layering is coated with, roller coating, screen printing, spraying, dip-coating, curtain flow coat cloth or the like; when the thickness of film is reduced to 1 mil when following; the coating process that is suitable for all lost efficacy; for example, little or for making dissolution characteristics less than 4 mils, in present known technology 25% of the characteristic size of the thickness preferred dissolution of used protectiveness film or still less.Use these methods will obtain thickness, a lot of open defects can occur in the coating of gained less than 1 mil.
A kind of method of avoiding occurring the problems referred to above is with electro-deposition photoetching agent.For example, make matrix charged earlier, adsorb charged photoetching agent more successively, photoresist is coated on the matrix with such method.See people's such as Demmer US 4632900 and 3,954,587 two pieces of patents of US of Kokawa.Therefore, available electrodeposition process directly forms film against corrosion on the surface of electroplating ventilating hole, thereby has avoided using the method that hides at upper berth, hole film, causes the troublesome problem of annular ring and film breakage etc.Yet, the time that electrodeposition process need be equipped with additional electrodeposition apparatus and lay this equipment.Electrodeposition process also will consume electricity and require charged resin.Even be coated in lip-deep photoresist best composition ratio is arranged usually, but by the preferential deposition of electro-deposition owing to some charged particle, the composition that in fact is deposited ratio may change.Therefore wishing to have a kind of like this method: it had both had the advantage of electrodeposition bath, even matrix can be coated with effectively and protect, the problem that is run in the time of avoiding making Means of Electrodeposition again.
Therefore, catalogue of the present invention be to provide a kind of metal surface that makes to be coated with method and emulsion with selective protection effectively, realize that this purpose is to make this surface deposition one deck protective finish in a kind of emulsion by simply the surface being immersed in.Then coating is carried out selectivity and handle, the coating of some part on this surface is kept.This method comprises:

Suitable initiators for polymerization comprises the radical initiator as crossing bisulfate and persulfuric acid ferrous acid formula sulfate or meta-acid formula sulfate system.The detailed process of emulsion polymerization, method and condition all have explanation in following these books: F.W.Billmeyer.Textbook of Polymer Science(Wiley-Interscience, New York; 2 ed 1971); K.Bovey. wait people Emulsion Polymerization(Interscience Publishers, Inc; New York 1955); And G.M.Dekker, Kinetics and Mechanisms of Polymerization Vol 1(Ed.by G.E.Ham 1969).
A kind of preferred emulsion wherein resin (ⅰ) is not made the emulsification shape earlier, can by directly make (ⅰ) and (ⅱ) method of emulsification prepare.Can adopt the emulsifying process of standard under some situation.See the Encyclopedia of Chemical Technology the 3rd edition of the US 4,177,177 of Vanderhoff and Kirk-Othner, Vol 8. " Emulsiuns-Preparation ", pp 919-923.Some situation is that some resin and photoactivation functional group may need to use other emulsifying process in addition.For example a kind of preferred emulsification method is a technology of taking inversion of phases to combine with efflorescence.Specifically, at room temperature, resin (ⅰ) and photoactivation functional group (ⅱ) are mixed wiring solution-forming in organic solvent (as ethyl acetate), in this solution, add low amounts of water (for example about 50% of solution weight) again and make it to form Water-In-Oil (W/O) emulsion.By adding the surfactant that some are known, as sodium alkyl benzene sulfonate, the aqueous solution of the surfactant that sodium alkyl sulfate or alkylphenol ethoxylate are such makes the above-mentioned W/O emulsion that generates change into oil-in-water (O/W) emulsion then.Sometimes also need to add surfactant again and finish such conversion.In order to stablize the emulsion of gained, adopt known levelling agent or the most handy ultrasonic method to make this emulsion efflorescence.Above-described any resin can both adopt this technology.
Said in routine 3-14 is the another kind of method that forms (ⅰ) and potpourri (ⅱ).Specifically, can make a kind of resin latex with the emulsion polymerization technique of above-mentioned resin by standard discussed above.The latex that generates has comprised the resin particle of formation emulsion resin (ⅰ).
This concrete latex among this embodiment is not standard.Latex particle preferably has certain photoactivation functional group in use, because they appear to make this functional group component emulsification.In addition, known to the person skilled in art, thereby they can provide acid function group can remove uncured coating with comparalive ease when using alkaline-based developer to coating.And because this latex is normally used the material preparation of high molecular, so latex plays filler, makes the coating more even.The latex of various kinds all is ready-made, and they all are to be made by the monomer that is suitable for preparing resin (ⅰ).
The latex of commercial sale has: the Darex that the organic chemistry branch office of W.R.Graee ﹠ Co-Conn produces The Acrysol that Rohm ﹠ Haas produces ASE-75 also is suitable for.
Latex in use, available previous said this group surfactant emulsification (ⅰ) and (ⅱ) two components, this helps to deposit.The commercial surfactant that is used for the embodiment of the invention is Air Products, the Surfynol TG surfactant that Inc produces.
When adopting above-mentioned any method to prepare emulsion, (ⅰ) and the total content that should be enough to make solid in this emulsion of consumption (ⅱ) in about 1-20%(weight) scope in.
Form after the emulsion at (ⅰ) with (ⅱ), acid (ⅲ) and oxygenant (ⅳ) are added in this emulsion.This acid and oxygenant are known in the deposition field automatically.It is generally acknowledged that acid and oxygenant make metal dissolve from the metal surface, produce metallic ion simultaneously.Thereby these metallic ions are considered to make the emulsion unstability near the metal surface that resin particle in the emulsion is deposited from the teeth outwards.See the US 4177180 of Hall.The example of acid comprises hydrochloric acid, hydrofluorite, phosphoric acid, citric acid, sulfuric acid and acetate.A kind of example of oxygenant is a hydrogen peroxide.The amount that adds acid should make the pH value of resulting emulsion generally in the 1-5 scope, preferably in the 1.7-3 scope.In some cases, metal halides such as also available cupric chloride and iron chloride are as oxygenant.In certain automatic deposit solution, also slaine can be comprised as requested, as metal halide, even other oxygenant has been arranged in solution (as H 2O 2) exist.For example in certain latex-based emulsion, can be with CuCl 2And H 2O 2Combine use.Under certain conditions, add CuCl 2Help the formation of deposition automatically.See example 5 and 7-12.
In addition, when use contains the emulsion that is pre-formed resin latex,, find the acid and the oxygenant of certain combination as said those emulsions among the routine 3-14, more more suitable than other array mode that the suitable automatic deposition emulsion of those preparations is used.Among some following embodiment these comparatively suitable array modes have been described, but other known combination can be suitable for also in automatic deposition technique.
Used surfactant (ⅴ) can be any surfactant well known in the prior art in the automatic deposition emulsion of the present invention, before they comprise in emulsifying process cited those, and except those used when the emulsion of preparation resin and photoactivation functional group surfactants, preferably add them again.
The emulsion weight percentages of components
Suitable is preferred
Resin 0.5-18.0 1.8-9.0
The 0.1-10.0 0.15-8.0 of photoactivation functional group
Surfactant total amount 0.5-5.0 1-2
Oxygenant 0.05-5.0 0.1-1.0
Also can comprise other adjuvant in this emulsion.These adjuvants can be used as the original emulsion a kind of component when forming, perhaps emulsion is made into after with they addings, this depends on used adjuvant.These adjuvants comprise (but being not limited to) coalescer, stabilizing agent, pigment, flow promortor and adhesive accelerant.The commercially available stabilizing agent that is used for negativity photoactivation functional group comprises quinhydrones, to methoxyl phenol, and pyrogallol, 2.6-two-tert-butyl group-4-cresols and phenothiazine.Commercially available flow promortor comprises the Modaflow of Monsanto Lithene PL with Rivertex Commercially available pigment and dyestuff comprise any various kind, for example the Neopen Blue 808 of BASF Suitable coalescer is glycol ether and ester.The PM Acetate of Eastmam Chemical Co for example

The automatic deposition technique of employing standard obtains (ⅰ) and coating (ⅱ) on the metal surface.For example, the surface is soaked about 30 seconds to 15 minute in emulsion.After obtaining desired coating thickness, from emulsion, take out this surface that was coated with at surface impregnation, and preferably its flushing and dry.
Then, the figure of the metal surface after this coating by imaging is exposed to actinic radiation.Make circuit diagram and positive functional group herein and be used as photoactivation functional group (ⅱ), coating is by transparent visual exposure, and therefore the coating that only stays on the metal position that is not subjected to the corrosive liquid corrosion does not have exposure.If usefulness is the negativity functional group, then can make coating radiation exposure on the uncorroded metal position by this transparent image.
The used radiation light wavelength of the present invention is 200-600nm preferably.Suitable radiating light source comprises arc, carbon, mercury vapour electric arc, and the phosphorus fluorescent light of emission ultraviolet light, argon and xenon glow lamp, tungsten lamp, photoflash, mercury vapour electric arc wherein, fluorescent light and metal halide lamp are the most suitable.The exposure required time depends on various factors, and they comprise each used in example emulsion photoactivation group, the ratio of these groups in emulsion, and light source type, and light source is from the distance of composition.The suitable time can be by determining with the similar technology of photographic imaging technology at an easy rate.
Used developer in the method for the present invention is selected according to the character of resin and photoactivation functional group and photolytic product, can be the aqueous organic solution of a kind of aqueous solution or alkali; Perhaps a kind of organic solvent or mixed solvent.The most handy a kind of alkali generates a kind of salt, thereby makes some regional photoactivation functional group or resin part (this coating will be removed after the irradiation) solubilize that stays in coating.Such alkaline solution is typically the NaOH or the potassium hydroxide of 0.25-3.0% weight or sodium carbonate or sal tartari.With radiation became resemble development after, some position of metal surface stays coating, goes out and other position is naked.For example, if use the positivity functional group, the coating that exposure is crossed is removed and nakedly goes out the metal surface.On the other hand, when using the negativity functional group, what be removed is the coating crossed of exposure not.Therefore, any situation no matter, the image that obtains of developing all be optionally coating and can stay imaging the metal surface " former state " or do further processing.
In one embodiment, carrying out selectively applied surface is copper, and it further is processed into the circuit board of circuit.As mentioned above, the procedure of processing of being taked is exactly to handle the copper surface in a kind of corrosive liquid.Some corrosive liquids that can be used to remove the naked copper metal after the development are well known in the prior art, and can change according to metal surface character.For example, general with acid ammonium persulfate solution, cupric chloride or ferric chloride solution for the copper surface.Another kind of cupric chloride corrosive liquid is the aqueous ammonium hydroxide/cupric chloride of alkalescence.
Other suitable surface is a copper laminated board, and wherein layer of copper is laminated on above the enhancement layer.The enhancement layer that is suitable for comprises paper, epoxy resin, glass-reinforced epoxy resin, polyimide, teflon or the like.
The positive resist coating surface after corrosion, topped the coating of shielded metallic pattern, exposure in actinic radiation makes coating become solubility.Then, the positivity coating that all exposures are crossed is removed it with a kind of stripping solution (using the NaOH aqueous solution usually).And the negativity coating that exposure is crossed is then generally used 3-5%(weight) sodium hydrate aqueous solution by the method for thermojet (57) it is removed.
As mentioned above, with the method that deposits emulsion automatically conductive hole or " through hole " in the double-sided wiring board are protected.Since adopt automatic sedimentation, the surface-coated lid of the conducting metal lining of these apertures, and protect these surfaces to avoid corrosion effectively.Therefore, the protective effect of above-mentioned emulsion equals the protection that electrodeposition process obtains, but more advantage is that it does not need electromotive force to produce equipment, does not need to make the additional process steps of this metal surface energising yet.And resin (ⅰ) and functional group (ⅱ) do not need the processing that makes it charged, the preferential deposition that does not yet have the electro-deposition owing to this charged particle to cause.
For making circuitous pattern on the plate of electroplating ventilating hole is being arranged, the positivity system sometimes is better than the negativity system in addition.For example, when adopting the lining in negativity imaging system protection hole, coating on these little internal surface of hole is shone fully and carry out polymerization, thereby become insolublely, this is very difficult.Therefore, possiblely be, this coating composition and not exclusively anti-common development and corrosion treatment, and the clad lining in this aperture may be corroded, and is not corroded although do not wish it.
On the other hand; use the positivity functional group then to avoid above-mentioned problem; because being designed to block through hole, positivity photograph instrument avoids actinic radiation; therefore; because the positive resist coating that is not irradiated to is insoluble; thereby still intactly keep in developing process and after developing and be without damage, protected lining to avoid the corrosion of corrosive liquid.
In order further to explain enforcement of the present invention and advantage thereof, enumerate the following example.But these examples are not restrictive, and only are illustrational.
