Specifically, good compatibility, especially high frequency characteristics (low dielectric constant, low dielectric loss tangent), high adhesion to conductors, excellent heat resistance, low thermal expansion characteristics, high flame resistance and high glass transition temperature
- the present invention relates to a thermosetting resin composition, a resin varnish, a prepreg, a metal-clad laminate, a multilayer printed wiring board, and a polyphenylene ether derivative used for these.
- thermosetting resin a resin composition used for a printed wiring board required to have low transmission loss
- a resin composition containing a polyphenylene ether and an epoxy resin for example, see Patent Document 1

- Patent Documents 1 to 5 are generally insufficient in high-frequency characteristics in the GHz range, adhesion to conductors, thermal expansion characteristics, and flame retardancy. Moreover, since the compatibility of polyphenylene ether and a thermosetting resin is low, heat resistance was inadequate. When the polyphenylene ether ratio in the resin composition is increased in order to suppress deterioration of the high frequency characteristics, the above-described chemical resistance (solvent) resistance, heat resistance, and moldability tend to be insufficient.
- the inventors of the present invention also have compatibility, heat resistance, thermal expansion characteristics, based on polyphenylene ether resin and polybutadiene resin, and semi-IPN in the production stage (A stage stage) of the varnish (resin composition).

- printed circuit board materials used in network-related equipment applications such as servers and routers must be multi-layered as the density increases, requiring high reflow heat resistance and through-hole reliability.
- the glass transition temperature serving as a guideline for them is 190 ° C. or higher, further 200 ° C. or higher, and the low thermal expansion property (Z direction, Tg or lower) is 45 ppm / ° C. or lower, and further 40 ppm / ° C. or lower. It is hoped that there will be.
- it is effective to add an inorganic filler to the resin composition for the expression of low thermal expansion, but in the case of a high multilayer printed wiring board, an inorganic filling is required to ensure resin flow for circuit filling.
- the amount of agent used is limited. Therefore, it is desirable to ensure the above-mentioned required value even when the amount of the inorganic filler used is relatively small at 25% by volume or less of the entire resin composition.
- the relative dielectric constant of the substrate material when a general E glass substrate is used is 3.7 or less, and further 3.6 or less, and the dielectric loss tangent is 0.8. It is desired to be 007 or less, and further 0.006 or less.
- the conventional dielectric characteristic values at 1 to 5 GHz there is an increasing need to satisfy the above-mentioned required values at a higher frequency band of 10 GHz or higher.
- JP 58-69046 A Japanese Patent Publication No. 61-18937 JP-A-56-133355 JP 59-193929 A JP-A-3-275760 Special table 2000-509097 JP 2008-95061 A

○:巨視的(マクロ)な相分離や不均一なムラがない。
×:巨視的(マクロ)な相分離や不均一なムラがある。
上記工程により得られた樹脂ワニスを、厚さ0.1mmのガラス布(Eガラス、日東紡績株式会社製)に塗工した後、160℃で7分間加熱乾燥して、樹脂含有量(樹脂分)約54質量%のプリプレグを作製した。これらのプリプレグ6枚を重ね、その上下に、厚さ18μmのロープロファイル銅箔(FV-WS、M面Rz:1.5μm、古河電気工業株式会社製)をM面が接するように配置し、温度230℃(ただし、比較例調製例5~6は200℃)、圧力3.9MPa、時間180分間の条件で加熱加圧成形して、両面銅張積層板(厚さ:0.8mm)を作製した。なお、調製例1~20の樹脂ワニスを用いて作製したプリプレグ及び銅張積層板が実施例1~20に、比較調製例1~7の樹脂ワニスを用いて作製したプリプレグ及び銅張積層板が比較例1~7にそれぞれ相当する。
上記で得られたプリプレグの外観を観察した。外観は目視により評価し、プリプレグ表面に多少なりともムラ、スジ、発泡、相分離等があり、不均一又は表面平滑性に欠けるものを×とし、前記のような外観上の異常がないものを○とした。その評価結果を表6~8に示す。
上記で得られた銅張積層板について、成形性、誘電特性、銅箔引きはがし強さ、ガラス転移温度、熱膨張係数、はんだ耐熱性及び難燃性を評価した。その評価結果を表6~8に示す。銅張積層板の特性評価方法は、以下の通りである。
両面の銅箔をエッチングした積層板の外観を観察して成形性を評価した。成形性は目視により評価し、多少なりともムラ、スジ、カスレ、ボイド等があり、均一性又は表面平滑性に欠けるものを×、前記のような外観上の異常がないものを○とした。
(2)誘電特性
誘電特性(比誘電率、誘電正接)は、JPCA-TM001(トリプレート共振器法)に準拠して、3GHz帯及び10GHz帯で測定した。
