Gold Bonding Wire
-
Product Description
Gold bonding wire is a critical interconnect material for semiconductor and microelectronic packaging. Manufactured from high-purity gold, it is used to electrically connect semiconductor dies to package leads or substrates via thermosonic wire bonding. With excellent electrical conductivity, superior oxidation and corrosion resistance, and consistent bondability, gold bonding wire ensures reliable signal and power transmission across a wide range of IC, LED, and optoelectronic packages. JFM offers gold bonding wire in a variety of diameters, purity grades, and spool configurations to meet diverse packaging requirements, delivering stable, high-yield performance for precision assembly processes.
Key Features
Gold bonding wire is engineered for thermosonic ball bonding in microelectronic packaging and offers the following characteristics:
- High purity (4N, ≥99.99% Au) for reliable long-term electrical and mechanical performance.
- Excellent electrical conductivity, ensuring low-resistance interconnects and high-speed signal transmission.
- Superior bondability with consistent Free Air Ball (FAB) formation and strong first/second bonds.
- Outstanding oxidation and corrosion resistance for extended shelf life and stable bonding quality.
- Consistent mechanical properties — tightly controlled breaking load and elongation for repeatable loop profiles.
- Compatible with fine-pitch and multi-tier packaging — supports advanced IC, memory, and system-in-package designs.
- Wide range of diameters and spool sizes available to suit various wire bonder platforms and application requirements.
Application Areas
Gold bonding wire is widely used in the following semiconductor and microelectronic packaging applications:
- IC Packaging: QFP, QFN, BGA, SOIC, TSOP, CSP, SiP, and other standard and advanced semiconductor packages.
- LED Packaging: LAMP, SMD, COB, and high-brightness LED interconnects.
