Description
本発明に係る高誘電ゴム樹脂材料は、液体ゴムを含み、液体ゴムの特性を制御することにより、ゴム樹脂材料での液体ゴムの添加量を従来の技術における液体ゴムの添加量の上限より高くすることができる。このように、本発明に係る高誘電ゴム樹脂材料は、高周波基板材料としてより好適である。
本願に係る高誘電ゴム樹脂組成物は、40~70重量%(wt%)の液体ゴムと、10~30重量%のポリフェニレンエーテル樹脂と、20~40重量%の架橋剤とを含む。
無機フィラーの添加により、高誘電ゴム樹脂材料の粘度を低減させ、且つ高誘電ゴム樹脂材料の比誘電率を低減させることができる。一部の無機フィラーは、ゴム樹脂材料の熱導電性を向上させることもあり、上述した説明は概に説明したものであり、本発明はこれに制限されるものではない。
高誘電ゴム樹脂材料は、シロキサンカップリング剤を更に含んでもよい。シロキサンカップリング剤の添加は、繊維布、高誘電ゴム樹脂組成物及び無機フィラーの間の反応性及び相容性を向上させ、高誘電金属基板の剥離強度及び耐熱性を向上させることができる。
高誘電ゴム樹脂材料は、難燃剤を更に含んでもよい。難燃剤の添加により、高周波基板の難燃性を向上させることができる。例えば、難燃剤は、リン系難燃剤又は臭素系難燃剤であってもよい。好ましくは、難燃剤はハロゲンフリー難燃剤であり、即ち、臭素を含まないものである。
本発明に係る高誘電ゴム樹脂材料が高周波基板材料として用いられることを証明するために、本発明において、40~70重量%の液体ゴムと、10~30重量%のポリフェニレンエーテル樹脂と、20~40重量%の架橋剤とを混合することにより、高誘電ゴム樹脂組成物を製造して、高誘電ゴム樹脂組成物に無機フィラーを配合し、それによって、実験例1~9に係る高誘電ゴム樹脂材料を製造した。実験例1~9の高熱伝導性ゴム樹脂材料の成分比率は、表1に示す通りである。
(1)比誘電率(10GHz):誘電分析装置(Dielectric Analyzer)(品番:HP Agilent E5071C)を用いて、10GHzの周波数での比誘電率を測定する。
(2)誘電正接(10GHz):誘電分析装置(Dielectric Analyzer)(品番:HP Agilent E5071C)を用いて、10GHzの周波数での誘電正接を測定する。
(3)剥離強度:試験方法IPC-TM-650-2.4.8に基づいて、銅箔基板の剥離強度を測定する。
(4)耐熱性:圧力鍋において温度120℃、圧力2atmで銅箔基板を120分加熱して、288℃のはんだ付け炉に浸し、基板がポップコーンするまでにかかる時間を記録する。ポップコーンするまでにかかる時間は10分間を超えると、「OK」を示す。ポップコーンするまでにかかる時間は10分間より低いと、「NG」を示す。
本発明の有利な効果として、本発明に係る高誘電ゴム樹脂材料及び高誘電金属基板は、「高誘電ゴム樹脂組成物は40~70重量%の液体ゴムを含む」及び「高誘電ゴム樹脂組成物は無機フィラーを含む」といった技術特徴により、誘電特性、剥離強度、及び耐熱性を向上させる。
