Description

Compositions of thermosetting resin and cured coating film thereof
Technical field
The present invention relates to be used for not halogen-containing, the compositions of thermosetting resin of the manufacturing of printed-wiring board (PWB) with flame retardant resistance.In more detail, relate to and be used for the solder resist that uses at printed-wiring board (PWB) and the compositions of thermosetting resin of marking ink, this resin combination is water-disintegrable low, at solder heat resistance, chemical resistance, adaptation, aspects such as electrical insulating property are good, and it is not halogen-containing, has stable flame retardant resistance, further, also relate to and be suitable for that (belt engages automatically: Tape Automated Bonding) at TAB, CSP (chip size packages: Chip Size Package), Chipon Film) (tape carrier encapsulation: semi-conductor carrier band that uses TapeCarrier Package) and COF (cover brilliant film: the compositions of thermosetting resin and the cured coating film thereof of the solder resist of flexible printed-wiring board (PWB) such as to TCP, this resin combination folding resistance is good, and the distortion after the curing is less.
Background technology
The solder resist that is used for the manufacturing of printed-wiring board (PWB) not only is used to protect irrelevant circuit when welding sequence; plating resist agent during sometimes also as electroplating processes; and then also have the effect of the protective membrane of the circuit after the welding, the insulating reliability after chemical resistance the when thermotolerance in the time of therefore must having welding, electroplating processes and the welding concurrently.In addition, for the semi-conductor carrier band that in TAB (Tape Automated Bonding), CSP (Chip Size Package), TCP (Tape Carrier Package), uses and the solder resist of COF flexible printed-wiring board (PWB)s such as (Chip onFilm), the also necessary folding resistance of cured coating film is good, and the distortion after the curing is less.
In addition, for printed-wiring board (PWB) that outside battery-driven machinery, uses etc., also must have flame retardant resistance.Further, nearest for the method for this fire-retardantization, because contained halogen compounds may be to cause there are two English etc. that in burning ashes therefore requirement does not contain halogen and gives its flame retardant resistance in resin and organic materials.
As this solder resist and marking ink, for example proposed, the composition (with reference to patent documentation 1) that forms by liquid-state epoxy resin, body pigment, tinting pigment, solvent and imdazole derivatives, the composition (with reference to patent documentation 2) that is formed by the multipolymer and the Resins, epoxy of acrylic or methacrylic acid and vinylbenzene etc., still anti-plating etc. is insufficient.In addition, when using it for semi-conductor carrier band and flexibility printed circuit board, it is insufficient to have a folding resistance, the problem that the distortion after the curing is bigger.
Further, have as the general method that makes this fire-retardantization of compositions of thermosetting resin, halid methods such as adding brominated epoxy resin, adding phosphoric acid ester are as the method for fire retardant and the method for adding red phosphorus etc.But, in view of advocating not halogen-containing present situation, so avoid adopting halid methods such as adding brominated epoxy resin.In addition, in the electroplating processes of method when printed-wiring board (PWB) is made of adding phosphoric acid ester etc., the phosphoric acid ester hydrolysis, has the problem that coating characteristics such as making electrical insulating property and electrocorrosion reduces, and then the method that adds red phosphorus has because red phosphorus is painted etc. and causes bad order, and the problem that is subjected to the restriction of fire service law etc. when storage solder resist composition.
The solder resist of using as flexibility printed circuit board, following type is arranged, after with mould the Kapton that is called mulch film being carried out molding with the pattern correspondence, the type of pasting with tackiness agent, form the ultraviolet hardening that has flexible and film, the solder resist printing ink or the liquid polyimide ink of heat curing-type, the type by the silk screen printing coating and forming has the type of the liquid photoresistance solder paste China ink that flexible films.
Yet, for tectum, though can not halogen-containing and fire-retardant change since with the tracing ability existing problems of Copper Foil, have the problem that can not form patterns of high precision.On the other hand, for ultraviolet hardening solder resist printing ink and liquid photoresistance solder paste China ink, the adaptation between itself and the polyimide base material is poor, has the sufficient flexible problem that can not get.In addition because the cure shrinkage of solder resist printing ink and solidify after cooling shrink greatlyyer, can produce distortion and become problem.Further, though proposed to use the composition (with reference to patent documentation 3) of solubility aromatic polyimide as liquid polyimide ink, it has costing an arm and a leg, produce bleeding when printing, can not get the problem of sufficient operability.

With above-mentioned acid resistance similarly, the substrate that obtains was flooded 30 minutes in the aqueous sodium hydroxide solution of 50 ℃ 10wt%, after the washing, peel off experiment by the glassine paper adhesive tape, resist peeled off variable color evaluation.
Zero: do not find fully to change
△: extremely small variation occurs
*: on filming, produce and peel off
(5) folding resistance
Be printed on each kapton material (high strength polyimide material) (thick 50 μ m) by silk screen printing each compositions of thermosetting resin comprehensively, solidify 30 minutes (dry film thickness 20 μ m) down at 150 ℃ with the foregoing description 2~4.
The cured film that obtains is folded 180 ° laterally, according to following benchmark evaluation.
Zero: do not have crackle on the cured film
△: a small amount of crackle is arranged on the cured film
*: crackle is arranged on the cured film
(6) distortion
Be printed on each kapton material (150 * 110mm, thick 25 μ m) by silk screen printing each compositions of thermosetting resin comprehensively, solidify 30 minutes (dry film thickness 20 μ m) down at 150 ℃ with the foregoing description 2~4.After the cooling, the distortion of the cured coating film that obtains according to following benchmark evaluation.
Zero: not distortion fully
△: a little distortion occurs
*: distortion appears
From the result shown in the table 2 as can be seen, not halogen-containing from the cured coating film that compositions of thermosetting resin of the present invention makes, has the same flame retardant resistance of cured article with the halogen-containing Resins, epoxy of use of comparative example 3, good characteristic with chemical resistance aspects such as acid resistance, alkali resistances.On the other side, the comparative example 1 that does not add the phosphoamide compound shown in the general formula (I) does not have flame retardant resistance.On the other hand, though the comparative example 2 that has added as the triphenylphosphate of general phosphoric acid ester fire retardant demonstrates flame retardant resistance, acid resistance, alkali resistance are relatively poor.
