Description

【0001】
【発明の属する技術分野】
本発明は、耐熱性に優れ、誘電特性に優れた樹脂組成物、プリプレグ及び積層板に関するものである。特に、高周波用回路基板の用途に好適に用いられるものである。
【0002】
ノート型パーソナルコンピューターや携帯電話等の情報処理機器は小型化が求められている。LSI等の電子部品を搭載するプリント配線板においても小型軽量化の要求は強くなっている。小型軽量化のためには配線幅を小さくすることや、スルーホール径を小さくしメッキ厚を薄くすることが必要である。メッキ厚を薄くすると熱衝撃時にメッキクラックが発生するおそれがあり、耐熱性が要求される。また同時にこれらの情報処理用危機の高速化も要求されておりCPUクロック周波数が高くなっている。そのため信号伝搬速度の高速化が要求されており、高速化に有利な誘電率、誘電正接の低いプリント板であることが必要とされる。
【0003】
耐熱性に優れ、誘電特性に優れた樹脂としてシアネート樹脂が用いられる(例えば、特開平8−8501号公報)。シアネート樹脂は硬化反応によって水酸基などの分極の大きい反応基が生じることがないため、誘電特性が非常に優れている。しかしながら窒素原子を多く含むため吸水率が高い欠点がある。
【0004】
【発明が解決しようとする課題】
本発明は、このような問題を解決すべく検討結果なされたものであり、シアネート樹脂とフェノールアラルキルエポキシ樹脂又はビフェニルアラルキルエポキシ樹脂を併用することで耐熱性、誘電特性、吸水率に優れた樹脂組成物、プリプレグ及びプリプレグから得られた積層板を提供するものである。

【発明の実施の形態】
本発明で用いる(A)成分のシアネート樹脂は下記一般式(I)で示される。
【化5】
Figure 0004738622
また、かかる一般式を有するシアネート樹脂をプレポリマー化したものも成形性、流動性を調整するために好ましく使用され、本発明の(A)成分に含まれるものである。プレポリマー化は、通常加熱溶融して行われる。本発明でプレポリマーとは、3量化率20〜50%のものをいう。3量化率は赤外分光分析装置を用いて求めることができる。なお、シアネート樹脂とシアネート樹脂をプレポリマー化したものとを併用しても構わない。
シアネート樹脂は樹脂成分100重量部中、50〜80重量部が好ましい。50重量部未満では260℃の半田耐熱性が十分でなく、また80重量部を越えると吸水率が悪化し好ましくない。
本発明におけるシアネート樹脂のR1のアルキル基は炭素数1〜6が好ましく、アリール基は炭素数は2〜6が好ましい。また、同様にR2のアルキル基は炭素数1〜4が好ましく、アリール基は炭素数1〜3が好ましい。
【0007】
本発明で用いる(B1)成分のビフェニルアラルキル樹脂は下記一般式(II)で示される
【化6】
Figure 0004738622
フェニルアラルキルエポキシ樹脂は樹脂成分100重量部中、20〜50重量部が好ましい。20重量部未満では低吸水化が十分でなく、また50重量部を越えると260℃の半田耐熱性が悪化し好ましくない。フェニルアラルキルエポキシ樹脂、エポキシ当量が大きく低吸水化の効果が大きい点で好ましい。
また、本発明でビフェニルアラルキル樹脂のnは2〜7が260℃の半田耐熱性の点で好ましい。nが2未満であると架橋密度が低下する傾向があり260℃での半田耐熱性が悪化する場合があり、7を超えるとシアネート樹脂との相溶性が悪化する場合がある
【0008】
前述のように、シアネート樹脂は硬化反応によってトリアジン環を生じるが、トリアジン環は対称性に優れているため分極が小さく誘電特性が非常に優れている。更に、トリアジン環は窒素を含む剛直構造であるため難燃性に優れている特徴がある。
しかし、シアネート樹脂は、窒素含有率が高いため、吸水率が高い欠点がある。吸水率を低下させるためには、エラストマーやジシクロペンタジエン樹脂などの低吸水樹脂を添加する方法があるが、これらの樹脂は燃焼しやすい欠点がある。本発明ではこの問題を解決するため、シアネート樹脂にフェノールアラルキルエポキシ樹脂又はビフェニルアラルキルエポキシ樹脂を併用する。フェノールアラルキルエポキシ樹脂、ビフェニルアラルキルエポキシ樹脂はエポキシ当量が大きく、硬化物中のエポキシ基濃度が小さくなるため誘電特性に優れている。また分子中のベンゼン環によって疎水性が高く吸水率も低い。また、フェノールアラルキルエポキシ樹脂、ビフェニルアラルキルエポキシ樹脂は、ベンゼン環含有率が高く炭化しやすいため、燃焼しにくくシアネート樹脂の優れた耐燃性を悪化させない。さらにエポキシ基はシアネート基と反応するため、樹脂骨格中に組み込むことができるためシアネート樹脂の優れた耐熱性を低下させない。
【0009】
本発明で用いる基材としては、ガラス繊布、ガラス不繊布、あるいはガラス以外を成分とする繊布又は不繊布等が挙げられる。これら基材の中でも強度、吸水率の点でガラス織布が好ましい。
【0010】
本発明で得られる樹脂組成物を基材に含浸させる方法には、含浸塗布設備等を用いる。
本発明においては、基材に含浸する際には通常溶剤に溶解したワニスの形で使用することが含浸性の点で好ましい。用いられる溶媒は組成に対して良好な溶解性を示すことが望ましいが、悪影響を及ぼさない範囲で貧溶媒を使用しても構わない。良好な溶解性を示す溶媒としては、メチルエチルケトン、シクロヘキサノン等が挙げられる。
本発明の樹脂組成物を溶剤に溶解して得られるワニスを、基材に含浸させ、80〜200℃で乾燥させることによりプリプレグを得ることが出来る。
【0011】
本発明で得られたプリプレグを1枚又は2枚以上重合わせ、150〜200℃で加熱加圧して積層板又は銅張積層板を得ることができる。
【0012】
本発明の樹脂組成物は、上述したシアネート樹脂とフェノールアラルキルエポキシ樹脂又はビフェニルアラルキルエポキシ樹脂を必須成分として含有するが、本発明の目的に反しない範囲において、その他の樹脂、硬化促進剤、カップリング剤、難燃剤、その他の成分を添加することは差し支えない。難燃剤として、臭素化エポキシ樹脂を用いると、エポキシ基とシアネート基が反応し、難燃剤を樹脂骨格中に組み込むことができるため、樹脂の特性を悪化させず好ましい。硬化促進剤としてはコバルトアセチルアセトナート、ナフテン酸コバルト等のコバルト含有化合物、塩化亜鉛、ナフテン酸亜鉛等の亜鉛含有化合物、塩化銅等の銅含有化合物が好ましい。

BACKGROUND OF THE INVENTION
The present invention relates to a resin composition, a prepreg, and a laminate having excellent heat resistance and excellent dielectric properties. In particular, it is suitably used for high frequency circuit boards.
[0002]
Information processing devices such as notebook personal computers and mobile phones are required to be downsized. There is an increasing demand for reduction in size and weight in printed wiring boards on which electronic components such as LSIs are mounted. In order to reduce the size and weight, it is necessary to reduce the wiring width, reduce the through-hole diameter, and reduce the plating thickness. If the plating thickness is reduced, plating cracks may occur during thermal shock, and heat resistance is required. At the same time, speeding up of these information processing crises is also demanded, and the CPU clock frequency is increasing. For this reason, it is required to increase the signal propagation speed, and it is necessary that the printed board has a low dielectric constant and low dielectric loss tangent, which is advantageous for increasing the speed.
[0003]
A cyanate resin is used as a resin having excellent heat resistance and excellent dielectric properties (for example, JP-A-8-8501). Since the cyanate resin does not generate a highly polar reactive group such as a hydroxyl group by the curing reaction, it has excellent dielectric characteristics. However, since it contains a lot of nitrogen atoms, it has a drawback of high water absorption.
[0004]
[Problems to be solved by the invention]
The present invention has been made as a result of studies to solve such problems, and by using a cyanate resin and a phenol aralkyl epoxy resin or a biphenyl aralkyl epoxy resin in combination, a resin composition excellent in heat resistance, dielectric properties, and water absorption rate. An object, a prepreg, and a laminate obtained from the prepreg are provided.
[0005]
[Means for Solving the Problems]
The present invention relates to (1) (A) a cyanate resin represented by the following general formula (I) or a prepolymer thereof, and
Figure 0004738622
(B1) A heat-resistant resin composition (not including a guanidine compound) containing a biphenylaralkyl epoxy resin represented by the following general formula (II) as an essential component , the general formula (II) The heat resistant resin composition (however, a guanidine compound is not included) characterized by containing 20-50 weight part of biphenyl aralkyl epoxy resins represented by these in 100 weight part of heat resistant resin compositions .
[Formula 4]

(2) A prepreg obtained by impregnating a base material with the resin composition according to item (1),
(3) A flame retardant laminate, wherein one or more prepregs according to (2) are superposed and heated and pressed,
(4) A copper-clad laminate obtained by superposing and heating and pressing the prepreg described in the item (2) and a copper foil.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The (A) component cyanate resin used in the present invention is represented by the following general formula (I).
[Chemical formula 5]
Figure 0004738622
Moreover, what prepolymerized cyanate resin which has this general formula is preferably used in order to adjust a moldability and fluidity | liquidity, and is contained in (A) component of this invention. The prepolymerization is usually performed by heating and melting. In the present invention, the prepolymer means a trimerization rate of 20 to 50%. The trimerization rate can be determined using an infrared spectroscopic analyzer. In addition, you may use together cyanate resin and what prepolymerized cyanate resin.
As for cyanate resin, 50-80 weight part is preferable in 100 weight part of resin components. If it is less than 50 parts by weight, the solder heat resistance at 260 ° C. is not sufficient, and if it exceeds 80 parts by weight, the water absorption rate is deteriorated.
The alkyl group of R1 of the cyanate resin in the present invention preferably has 1 to 6 carbon atoms, and the aryl group preferably has 2 to 6 carbon atoms. Similarly, the alkyl group of R2 preferably has 1 to 4 carbon atoms, and the aryl group preferably has 1 to 3 carbon atoms.
[0007]
The biphenyl aralkyl resin of component (B1) used in the present invention is represented by the following general formula (II) .
[Chemical 6]
Figure 0004738622
The biphenyl aralkyl epoxy resin 100 parts by weight of the resin component, preferably 20 to 50 parts by weight. If it is less than 20 parts by weight, the water absorption is not sufficiently reduced, and if it exceeds 50 parts by weight, the solder heat resistance at 260 ° C. is deteriorated, which is not preferable. Biphenyl aralkyl epoxy resin is preferable from the viewpoint effect of epoxy equivalent is large low water absorption is large.
In the present invention, n in the biphenyl aralkyl resin is preferably 2 to 7 in view of solder heat resistance at 260 ° C. If n is less than 2, the crosslinking density tends to decrease, and solder heat resistance at 260 ° C. may be deteriorated. If n exceeds 7, compatibility with cyanate resin may be deteriorated .
[0008]
As described above, the cyanate resin generates a triazine ring by a curing reaction. However, since the triazine ring is excellent in symmetry, the polarization is small and the dielectric property is very excellent. Furthermore, since the triazine ring has a rigid structure containing nitrogen, it is characterized by excellent flame retardancy.
However, since cyanate resin has a high nitrogen content, it has a drawback of high water absorption. In order to reduce the water absorption rate, there is a method of adding a low water absorption resin such as an elastomer or dicyclopentadiene resin. In the present invention, in order to solve this problem, a phenol aralkyl epoxy resin or a biphenyl aralkyl epoxy resin is used in combination with a cyanate resin. The phenol aralkyl epoxy resin and the biphenyl aralkyl epoxy resin have a large epoxy equivalent and a low epoxy group concentration in the cured product, and thus have excellent dielectric characteristics. The benzene ring in the molecule has high hydrophobicity and low water absorption. In addition, the phenol aralkyl epoxy resin and the biphenyl aralkyl epoxy resin have a high benzene ring content and are easily carbonized. Furthermore, since the epoxy group reacts with the cyanate group, it can be incorporated into the resin skeleton, so that the excellent heat resistance of the cyanate resin is not lowered.
[0009]
Examples of the substrate used in the present invention include glass fabric, glass fabric, and fabric or fabric containing components other than glass. Among these base materials, a glass woven fabric is preferable in terms of strength and water absorption.
[0010]
For the method of impregnating the substrate with the resin composition obtained in the present invention, an impregnation coating facility or the like is used.
In the present invention, when impregnating the base material, it is usually preferable from the viewpoint of impregnation to use it in the form of a varnish dissolved in a solvent. The solvent used preferably has good solubility in the composition, but a poor solvent may be used as long as it does not adversely affect the composition. Examples of the solvent exhibiting good solubility include methyl ethyl ketone and cyclohexanone.
A prepreg can be obtained by impregnating a base material with a varnish obtained by dissolving the resin composition of the present invention in a solvent and drying at 80 to 200 ° C.
[0011]
One or two or more prepregs obtained in the present invention are overlapped and heated and pressed at 150 to 200 ° C. to obtain a laminate or a copper-clad laminate.
[0012]
The resin composition of the present invention contains the above-described cyanate resin and a phenol aralkyl epoxy resin or a biphenyl aralkyl epoxy resin as essential components. Additives, flame retardants, and other ingredients may be added. When a brominated epoxy resin is used as the flame retardant, the epoxy group and the cyanate group react with each other and the flame retardant can be incorporated into the resin skeleton, which is preferable without deteriorating the properties of the resin. As the curing accelerator, cobalt-containing compounds such as cobalt acetylacetonate and cobalt naphthenate, zinc-containing compounds such as zinc chloride and zinc naphthenate, and copper-containing compounds such as copper chloride are preferable.
[0013]
【Example】
Example 1
70 parts by weight of bisphenol A cyanate resin (prepolymerized, trimerization rate 40%, C-40 Geigy B-40), biphenyl aralkyl epoxy resin (epoxy equivalent 280, Nippon Kayaku NC-3000S) 30 parts by weight, Dimethyl cellosolve was added to 0.10 parts by weight of the cobalt acetylacetone complex, and the varnish was adjusted so as to have a nonvolatile content concentration of 55% by weight.
Using this varnish, 100 parts by weight of glass fiber cloth (thickness 0.18 mm, manufactured by Nitto Boseki Co., Ltd.) was impregnated with 80 parts by weight of varnish solids, and dried in a dryer oven at 150 ° C. for 5 minutes to obtain a resin. A prepreg having a content of 44.4% was prepared.
6 sheets of the above prepreg are stacked, and 35 μm thick electrolytic copper foils are stacked on the top and bottom. The pressure is 40 kgf / cm 2 , the temperature is 200 ° C. for 120 minutes, and the temperature is 220 ° C. for 60 minutes, and the thickness is 1.2 mm. A double-sided copper-clad laminate was obtained.
[0014]
(Example 2 and Comparative Examples 1 to 5 )
A double-sided copper-clad laminate was prepared in the same manner as in Example 1 except for the formulation shown in Table 1 and Table 2 .
[0015]
The obtained copper-clad laminate was measured for flame retardancy, solder heat resistance, peel strength, and water absorption. Solder heat resistance, peel strength, and water absorption are measured according to JIS C 6481. Solder heat resistance is an abnormal appearance after being immersed in a solder bath at 260 ° C. for 120 seconds after performing a moisture absorption treatment for 2 hours after boiling. The presence or absence of was investigated. Flame retardancy was evaluated by a vertical method using a 1 mm thick sample in accordance with UL-94 standards. The glass transition point was measured using RDS-7700 manufactured by Rheometrics at a heating rate of 3 ° C./min and a frequency of 1 Hz. The dielectric constant and dielectric loss tangent were measured according to JIS C 6481 and measured by measuring the capacitance at a frequency of 1 MHz. The evaluation results are shown in Table 1. It can be seen that the copper-clad laminates shown in the examples all have low dielectric constant and dielectric loss tangent, and are excellent in heat resistance, solder heat resistance, and water absorption.
