Method for manufacturing composite lead frame |
摘要 |
An outer lead of a metal lead frame is connected to an inner lead of a flexible lead-patterned substrate via a Au-Sn alloy layer. The Au-Sn alloy layer contains Au of 10 to 40 weight %. An inner lead of a metal lead frame is connected to a patterned lead of a flexible lead-patterned substrate by a heating tool. The inner lead is coated on bottom and side surfaces of its tip portion. The bottom surface faces the patterned lead.
