Further, by imparting thixotropic properties to the resin composition, it is possible to prevent the resin composition from oozing out from the pores after the printing is filled or at the time of curing. Further, by imparting thixotropy, the resin composition can be closely filled with the irregularities of the copper surface in the pores at the time of filling.

发明人等为了解决上述问题而反复深入研究, 结果发现以含有 (A) 不 具有脂环骨架的环氧树脂、 (B) 具有脂环骨架的环氧树脂、 (C) 固化催化 剂、 (D)填料为特征的热固性树脂组合物能够解决上述问题, 从而完成本发 明。
即, 本发明的热固性树脂组合物的特征在于, 其为用于填充到印刷电路 板的孔的用途, 含有 (A) 不具有脂环骨架的环氧树脂、 (B) 具有脂环骨架 的环氧树脂、 (C) 固化催化剂、 (D) 填料。 另外, 本发明的印刷电路板的特征在于, 其具有填充有前述热固性树脂 组合物的固化物的孔部。
本发明的环氧树脂组合物通过含有 (A) 不具有脂环骨架的环氧树脂、 (B) 具有脂环骨架的环氧树脂、 (C) 固化催化剂、 (D) 填料, 能够抑制经 时变化中的组合物粘度的增粘。 其结果, 能够延长保存期间, 不需要严格的 保存管理。 此外由于可使用时间也变长, 因此能够防止作业性的降低, 可以 长时间稳定地使用。 具体而言, 由于即使长时间使用粘度也是稳定的, 因此 不仅对孔的埋入性不会变化而稳定, 而且还能够抑制在粘度增高时孔内的气 泡增加这样的不良情况。
特别是通过使用 (A) 不具有脂环骨架的环氧树脂, 能够获得适度的流 动性和固化物的硬度, 因此能够获得填充性和研磨性。 通过使用 (B) 具有 脂环骨架的环氧树脂, 借助抑制组合物的固化反应的作用, 抑制经时变化中 的组合物粘度的增粘成为可能。 因此, 如果欠缺两者中的一方, 就无法获得 全部的特性。
(D) 关于填料, 通过含有其能够起到热固化中收缩时的缓冲材料的作 用, 对树脂组合物赋予应力缓和的功能。 另外, 通过对树脂组合物赋予触变 性, 能够防止在印刷填充后、固化时树脂组合物由孔渗出的不良情况。此外, 通过赋予触变性,在填充时树脂组合物能够紧密地追随孔内的铜表面的凹凸 进行填充。 通过其后的固化, 树脂组合物与铜均匀地固化, 由此获得稳定的 密合性成为可能。
因此, 如果缺少 (D) 填料, 就无法获得全部的特征。
与此相反, 在现有的热固性树脂组合物中, 虽然能够获得填充性、 研磨 性, 但抑制经时变化中的粘度的增粘不充分。 其理由是由于在现有的热固性 树脂组合物中, 通常仅使用 (A) 不具有脂环骨架的环氧树脂, 且设计成反 应性快的树脂组成。 作为现有的对策, 制成 2液性是最为简单的方法, 但在 使用时必须混合 2液而招致作业性的降低。 这样, 在现有的热固性树脂组合 物中, 长时间稳定地使用是困难的。
有益效果
从以上情况出发, 通过本发明的热固性树脂组合物, 能够提供抑制经时 粘度的增粘、 对印刷电路板的孔的填充性、 固化后的研磨性优异的热固性树 脂组合物以及其印刷电路板。 具体实施方式
以下, 对本发明的热固性树脂组合物中的各构成成分进行说明。
作为(A)不具有脂环骨架的环氧树脂, 只要是在一分子中具有 2个以上 环氧基的物质即可,可以使用公知的物质。例如可列举出双酚 A型环氧树脂、 双酚 S型环氧树脂、 二萘酚型环氧树脂、 双酚 F型环氧树脂、 苯酚酚醛清漆型 环氧树脂、 甲酚酚醛清漆型环氧树脂、 丙二醇或聚丙二醇的二缩水甘油醚、 聚 1,4-丁二醇二缩水甘油醚、 甘油多缩水甘油醚、 三羟甲基丙垸多缩水甘油 醚、 苯基 -1,3-二缩水甘油醚、 联苯 -4,4'-二缩水甘油醚、 1,6-己二醇二缩水甘 油醚、 乙二醇或丙二醇的二缩水甘油醚、 山梨糖醇多缩水甘油醚、 山梨糖醇 酐多缩水甘油醚、 三 (2,3-环氧丙基) 异氰脲酸酯、 三缩水甘油三 (2-羟乙 基)异氰脲酸酯等在 1分子中具有 2个以上环氧基的化合物、 四缩水甘油氨基 二苯基甲垸、 四缩水甘油间苯二甲胺、 三缩水甘油对氨基苯酚、 二缩水甘油 苯胺、 二缩水甘油邻甲苯胺等胺型环氧树脂等。

在这些当中, 特别优选在制作粘度低的糊剂时能够增加填料的填充量、 且含有作为耐热骨架的苯环的胺型液态环氧树脂等。它们可以单独使用或者
2种以上组合使用。
(A) 不具有脂环骨架的环氧树脂的配混比例为组合物总量的 4~40质量 %, 优选为 10~38质量%, 进一步优选为 20~35质量%。 如果小于 4质量%, 则 组合物的反应性变差, 变得不能具有充分的硬度。 其结果, 有在研磨时引起 组合物的脱落等不良情况的可能性。 反之如果为 40质量%以上, 则无法抑制 经时粘度的增粘。
作为 (B) 具有脂环骨架的环氧树脂, 为在分子内具有环状脂肪族骨架 和 2个以上环氧基的化合物。 其中, (B) 具有脂环骨架的环氧树脂的环氧基 优选不含缩水甘油醚基。 作为 (B) 具有脂环骨架的环氧树脂的优选环氧基 为含有构成环状脂肪族骨架的 2个碳原子而形成的环氧基、 与环状脂肪族骨 架直接键合的环氧基。 作为这样的 (B) 具有脂环骨架的环氧树脂, 通过使 对应的脂环式烯烃化合物借助脂肪族过羧酸等氧化来制造,基本上使用无水 的脂肪族过羧酸来制造的物质具有高的环氧化率, 从该点出发而优选。
(B) 具有脂环骨架的环氧树脂具有连接基团, 例如可列举出单键、 亚 垸基、 羰基 (-CO-)、 醚键 (-0-)、 酯键 (-C00-)、 酰胺键 (-CONH -)、 碳 酸酯键(-0C00-)、 以及这些多个连接而形成的基团等。 其中优选的连接基 团为醚键(-0-)、 酯键(-C00-)。 亚垸基的碳原子数优选为 1~18, 可列举出 亚甲基、 甲基亚甲基、二甲基亚甲基、亚乙基、亚丙基、三亚甲基等直链状、 支链状的亚垸基、 1,2-环亚戊基、 1,3-环亚戊基、 环次戊基、 1,2-环亚己基、 1,3-环亚己基、 1,4-环亚己基、 环次己基等 2价的脂环式烃基(尤其 2价的环亚 垸基) 等。
(B) 具有脂环骨架的环氧树脂也可以从市场上入手, 例如优选的可示 例出作为连接基团为酯键的 "Celoxide 2021"、 "Celoxide 2081"、 作为连接基 团为醚键的' ΈΗΡΕ3150" (均为 DAICEL CHEMICAL INDUSTRIES, LTD.制 造), 其中特别优选的可列举出" Celoxide 2021"、 "ΕΗΡΕ 3150'Ό
(Β)具有脂环骨架的环氧树脂的配混比例为组合物总量的 2~38质量%, 优选为 4~31质量%, 进一步优选为 6~20质量%。 如果小于 2质量%, 则有时无 法抑制经时粘度的增粘。反之如果为 38质量%以上,则组合物的反应性变差, 有时无法具有充分的硬度。 其结果, 有时在研磨时引起组合物的脱落等不良 情况。
(Α) 不具有脂环骨架的环氧树脂与 (Β ) 具有脂环骨架的环氧树脂的 配混比率如下所示。以质量比计(A): (Β) =90:10~20:80,优选为 85:15~50:50, 进一步优选为 80:20~60:40。
即使 (Β ) 具有脂环骨架的环氧树脂的比率高会满足特性, 也由于如果 (Α) 不具有脂环骨架的环氧树脂的比率高, 则固化时间能够缩短而提高作 业性, 因此是期望的。
作为 (C) 固化催化剂, 只要是成为 (Α) 不具有脂环骨架的环氧树脂 和 (Β) 具有脂环骨架的环氧树脂的固化催化剂的公知惯用的物质, 就可以 使用任何物质, 具体而言可列举出下述物质。 SP, 商品名 2E4MZ、 C11Z、 C17Z、 2PZ等咪唑类、 商品名 2MZ-A、 2E4MZ-A等咪唑的 AZINE化合物、 商 品名 2MZ-OK、 2PZ-OK等咪唑的异氰脲酸盐、 商品名 2PHZ、 2P4MHZ等咪 唑羟甲基体 (前述商品名均为四国化成工业株式会社制造)、 双氰胺及其衍 生物、 三聚氰胺及其衍生物、 二氨基马来腈及其衍生物、 二亚乙基三胺、 三 亚乙基四胺、 四亚乙基五胺、 双 (六亚甲基) 三胺、 三乙醇胺、 二氨基二苯 基甲垸、 有机酸二酰肼等胺类、 1,8-二氮杂双环 [5,4,0] 十一烯 -7的辛基酸 盐、 磺酸盐 (商品名 DBU、 SAN-APRO公司制造)、 3,9-双 (3-氨基丙基) -2,4,8,10-四氧杂螺 [5,5 ] ^一垸 (商品名 ATU、 味之素株式会社制造)、 或 三苯基膦、 三环己基膦、 三丁基膦、 甲基二苯基膦等有机膦化合物等。 这些 与涂膜的特性提高的要求相匹配, 可以单独使用或者 2种以上组合使用。 另 外, 还可使用四丙烯基琥珀酸酐、 甲基四氢邻苯二甲酸酐、 甲基六氢邻苯二 甲酸酐、十二烯基琥珀酸酐、甲基内亚甲基四氢邻苯二甲酸酐等公知的酸酐。 在这些固化催化剂中, 特别是咪唑, 由于在环氧树脂的固化物中耐热性、 耐 化学药品性优异,另外能够获得疏水性, 因此能够抑制吸湿, 因而是适宜的。 另外,双氰胺、三聚氰胺、甲基胍胺、苯并胍胺、 3,9-双 [2- (3,5-二氨基 -2,4,6- 三氮杂苯基) 乙基] -2,4,8,10-四氧杂螺 [5,5 ]十一垸等胍胺及其衍生物、 以 及它们有机酸盐、 环氧加合物等由于已知具有与铜的密合性、 防锈性, 不仅 能够作为环氧树脂的固化剂起作用, 而且还能有助于防止印刷电路板的铜变 色, 因此可适宜地使用。
(C)固化催化剂的配混量用通常的量的比例是充分的,例如每前述(A) 不具有脂环骨架的环氧树脂和(B)具有脂环骨架的环氧树脂的总量 100质量 为 0.05质量份以上且 140质量份以下是适合的。优选为 0.1质量份以上且 120质 量份以下, 进一步优选为 0.3质量份以上且 100质量份以下。 如果小于 0.05质 量份, 则无法得到具有足够硬度的固化物。 其结果, 有产生在研磨时引起组 合物的脱落等不良情况的可能性。 如果为 140质量份以上, 则除了无法抑制 经时粘度的增粘之外, 还通常使树脂组合物的预固化速度变得过快, 在固化 物中易残留空隙, 故不优选。
(D) 填料是为了缓和由固化收缩带来的应力、 调整线膨胀系数、 此外 对树脂组合物赋予触变性而使用的物质,只要为在一般的树脂组合物中使用 的公知惯用的非导电性的物质, 就可以为任何物质。 具体而言, 例如可列举 出二氧化硅、 硫酸钡、 碳酸钙、 氮化硅、 氮化铝、 氮化硼、 氧化铝、 氧化镁、 氢氧化铝、 氢氧化镁、 氧化钛、 云母、 滑石、 有机膨润土、 高岭土、 诺易堡 硅土 (Sillitin)、 烧成高岭土粘土、 烧成滑石、 烧成诺勃氏 (Neuburg) 硅土 等非金属填料、 铜、 金、 银、 钯、 硅等金属填料。 这些与涂膜的特性提高的 要求相匹配, 可以单独使用或者 2种以上组合使用。 其中, 二氧化硅和碳酸 钙从特性方面、 作业方面优选。
(D) 填料的形状可列举出球状、 针状、 片状、 鳞片状、 中空状、 无定 形状、 六角状、 立方体状、 薄片状等, 不管任何形状均可。
(D) 填料的平均粒径, 其如果可以无特别适宜的范围地糊剂化, 能够 获得期待的特性, 则不管任何粒径均可。
另外, (D) 填料的表面处理无论有无处理均可。
(D)填料的配混比例优选为组合物总量的 30~90质量%, 进一步优选为 40~70质量%。无机填料的配混比例在小于 30质量%时,所得固化物无法显示 足够低的膨胀性, 此外研磨性、 密合性也变得不充分。 另一方面, 在超过 90 质量%的情况下, 糊剂化变得困难, 无法获得印刷性、 填孔填充性等。
在本发明的热固性树脂组合物中,在使用室温下液态的环氧树脂的情况 下, 不一定需要使用稀释溶剂, 但为了调整组合物的粘度, 也可以添加稀释 溶剂。 作为稀释溶剂, 例如可列举出甲基乙基酮、 环己酮等酮类; 甲苯、 二 甲苯、 四甲苯等芳香族烃类; 甲基溶纤剂、 丁基溶纤剂、 甲基卡必醇、 乙基 卡必醇、 丁基卡必醇、 丙二醇单甲醚、 二丙二醇单乙醚、 三乙二醇单乙醚等 二醇醚类; 醋酸乙酯、 醋酸丁酯、 以及上述二醇醚类的醋酸酯化物等酯类; 乙醇、 丙醇、 乙二醇、 丙二醇等醇类; 辛垸、 癸垸等脂肪族烃; 石油醚、 石 脑油、 氢化石脑油、 溶剂石脑油等石油系溶剂等有机溶剂。 它们可以单独使 用或者 2种以上组合使用。
稀释溶剂的配混比例优选为热固性树脂组合物的整体量的 10质量%以 下。 稀释溶剂的配混比例超过 10质量%时, 在固化时由于挥发成分的蒸发的 影响, 易于在孔部内产生泡、 裂紋。 更优选为 5质量%以下。
此外, 在本发明的热固性树脂组合物中, 根据需要可以配混酞菁,蓝、 酞菁■绿、 碘"绿、 双偶氮黄、 水晶紫、 氧化钛、 炭黑、 萘黑等公知惯用的着 色剂、用于赋予保管时的保存稳定性的氢醌、氢醌单甲基醚、叔丁基儿茶酚、 连苯三酚、 吩噻嗪等公知惯用的热阻聚剂、 粘土、 高岭土、 有机膨润土、 蒙 脱石等公知惯用的增粘剂或者触变剂、 有机硅系、 氟系、 高分子系等消泡剂 和 /或流平剂、 咪唑系、 噻唑系、 三唑系、 硅垸偶联剂等密合性赋予剂这样的 公知惯用的添加剂类。
本实施方式的热固性树脂组合物使用丝网印刷法、 辊涂法、 模头涂布法 等公知的图案化方法,填充至例如在表面和孔部的壁面形成有铜等的导电层 的印刷电路板的孔部。 此时, 按从孔部稍微突出的方式完全地填充。 接着, 将孔部用热固性树脂填充材料填充了的印刷电路板例如在 150°C下加热 60分 钟, 由此使热固性树脂填充材料固化, 形成固化物。
接着,将从印刷电路板的表面突出的固化物的不需要部分通过公知的物 理研磨方法除去, 进行平坦化。 接着, 将表面的导电层按规定图案进行图案 化, 形成规定的电路图案。 此外, 可以根据需要通过过锰酸钾水溶液等进行 固化物的表面粗化, 然后通过化学镀覆等在固化物上形成导电层。

从以上情况出发, 可知通过调制成实施例 1-4的热固性树脂组合物, 可 得到抑制经时粘度的增粘、 对印刷电路板的孔的填充性、 固化后的研磨性优 异的热固性树脂组合物。 与此相反, 比较例 1和 2由于反应性高而增粘率高, 此外固化物的硬度高,如果不设严研磨条件就无法研磨,因此研磨性不充分。 仅仅使用了 (B )具有脂环骨架的环氧树脂的比较例 3由于缺乏反应性, 虽然 可抑制增粘, 但固化物的强度和硬度不足, 在孔内的树脂组合物与铜的界面 产生剥离, 在研磨时连孔内的固化物也扯出般地脱落, 在研磨后固化物表面 未达到水平, 因此未得到填充性和研磨性。 比较例 4由于反应性高而未能抑 制粘度的增粘。 比较例 5由于反应性高而未能抑制粘度的增粘, 此外由于不 含填料的影响,树脂组合物的应力缓和不足而产生裂紋,因此未得到填充性。
