摘要:
本发明提供焊料凸点形成用树脂组合物,即使通过回流、烘焙等将基板暴露于高温的情况下也不阻碍抗蚀剂(干膜等)的去除性,并且焊料接合性优异。焊料凸点形成用树脂组合物,其特征在于,包含(A)酸值(mgKOH/g)为110以上的碱显像性热塑性树脂(其中,不饱和脂肪酸聚合物为酸值80以上),(B)溶剂和(C)焊料粉末,并且不含活性剂。
摘要(英):
The present invention provides a solder bump formation resin composition which ensures resist (e.g., dry film) removability and which exhibits excellent solder bonding performance, even when the working substrate is placed at high temperature during reflowing, baking, or a similar process. The solder bump formation resin composition contains (A) at least one species selected from among an alkali-dissoluble thermoplastic resin having an acid value (mgKOH/g) of 110 or higher, an unsaturated fatty acid polymer having an acid value of 80 or higher, and an unsaturated fatty acid-aliphatic unsaturated compound copolymer having an acid value of 50 or higher; (B) a solvent; and (C) a solder powder, and contains no activating agent.
