摘要
键合丝是发光二极管封装中应用的关键材料之一,是发光二极管高效封装的基础。由于键合金丝成本高企,众多LED封装厂家选择应用低成本合金丝来替代键合金丝。本文介绍了键合丝的特点和性能要求,综述了键合金丝、金合金丝、银合金丝的组成、性能、使用、可靠性等研究进展,并以北京达博有色金属焊料有限责任公司提供的4款产品为例进行了应用测试,比较了其性能差异,为合金丝的应用提供支持。
Bonding wire is one of the key materials applied in light emitting diode packaging.It is the foundation of high-efficient LED packaging.Due to the high cost of gold bonding wire,many LED packaging manufacturers chose low cost alloy bonding wire instead of gold bonding wire.This paper introduced the characteristics and the performance demands of bonding wire.The research progress on the composition,performance,application and reliability of gold bonding wire,gold alloy bonding wire and silver alloy bonding wire was summarized.Four products provided from Beijing Doublink Solders Co.,LTD were tested in LED packaging application as examples to compare their differences in performance,which can provide support for the application of alloy bonding wire.
