Abstract
Description
本実施の形態のフラックスは、溶剤と高粘性溶剤とチキソ剤を含み、ロジンを含まず、高粘性溶剤が1,2,6−ヘキサントリオール(高級アルコール)とイソボルニルシクロヘキサノール(テルペン誘導体)からなる。
本実施の形態のソルダペーストは、上述したフラックスと、金属粉を含む。金属粉は、Sn単体、または、Sn−Ag系、Sn−Cu系、Sn−Ag−Cu系、Sn−Bi系、Sn-In系、Sn−Pb系等、あるいは、これらの合金にSb、Bi、In、Cu、Zn、As、Ag、Cd、Fe、Ni、Co、Au、Ge、P、Pb等を添加したはんだの粉体で構成される。なお、金属粉は、Pbを含まないはんだであることが好ましい。
エアーディスペンス法、ジェットディスペンス法において、ノズルの詰まり抑制には、加圧時に速やかに流動することが重要である。また、ジェットディスペンス法での安定塗布には、ジェット吐出時のソルダペーストの液滴形状を安定させることが重要で、ソルダペーストの着弾時(基板等の塗布対象に当たった時)の飛散を抑制するには、ソルダペーストの液滴の尾の部分が切れずに着弾することが重要である。
(1)検証方法
ガラスエポキシ基板のCu張積層基板へ、エアーディスペンサーを用いて実施例のフラックスを使用したソルダペースト、比較例のフラックスを使用したソルダペーストを塗布した。各実施例、各比較例のソルダペーストについて、それぞれ6万ショットを連続塗布して、塗布性を判定した。判定結果は以下の判定基準に従って行った。なお、エアーディスペンサーのニードル、ノズル内径は、好ましくは0.1mm以上1.5mmであり、本検証では、0.35mmのものを使用した。また、塗布圧は、好ましくは80kpa以上200kpa以下であり、本検証では、100kpaとした。更に、塗布時間は、好ましくは80mmsec以上500mmsec以下であり、本検証では100mmsecとした。また、塗布温度は、本検証では25℃とした。なお、ノズルと基板のクリアランスの最適値は、吐出量により変化するが、本検証では0.2mmとした
〇:連続して安定した塗布量が得られた。
△:塗布量が安定しなかった。
×:塗布量が安定せず、未転写部が発生した。
(1)検証方法
ガラスエポキシ基板のCu張積層基板へ、ジェットディスペンサーを用いて実施例のフラックスを使用したソルダペースト、比較例のフラックスを使用したソルダペーストを塗布した。ジェットディスペンサーとしてはピエゾ式のジェットプリンターを用い、各実施例、各比較例のソルダペーストについて、それぞれ1万ショットを連続塗布して、塗布性を判定した。判定結果は以下の判定基準に従って行った。
〇:全パターンを狙い位置に塗布できた。
×:位置ずれ、ミッシングが発生又は多発した。またははんだが飛ばなかった。
