| 摘要 |
本发明系关于一种接合线材，其包括：一具有一表面(15)之芯(2)，其中该芯(2)包括选自由铜及银组成之群的芯主要组分；及一至少部分覆盖在该芯(2)之表面(15)上的涂覆层(3)，其中该涂覆层(3)包括选自钯、铂、金、铑、钌、锇及铱之群的涂覆组分；其中该涂覆层系藉由将液体膜沉积在一线材芯前驱物上而施用于该芯之表面上，其中该液体包含涂覆组分前驱物，及其中该沉积膜经加热以将该涂覆组分前驱物分解成金属相。; and a coating layer (3) which is at least partially superimposed over the surface (15) of the core (2), wherein the coating layer (3) comprises a coating component selected from the group palladium, platinum, gold, rhodium, ruthenium, osmium and iridium, wherein the coating layer is applied on the surface of the core by means of depositing a film of a liquid onto a wire core precursor, wherein the liquid contains a coating component precursor, and wherein the deposited film is heated in order to decompose the coating component precursor into a metallic phase. |
