June 24, 2025 - As global automotive semiconductor demand surges beyond $52.6B, Sichuan Winner emerges as an industry leader in copper wirebond solutions, addressing critical reliability and cost challenges in vehicle electronics packaging.
The Copper Wire Revolution
Following gold price volatility that peaked at $1900/oz in 2011, Sichuan Winner strategically invested in copper wirebond R&D. Today, 94% of automotive wirebond packages utilize copper, with Winner's Hybrid Cu Wire technology demonstrating superior HTSL performance at 175°C compared to traditional gold wires prone to Kirkendall voids.
Technical Breakthroughs
Winner's engineering team has overcome key copper wire challenges:
- Developed proprietary 2N Cu alloy formulations for enhanced HAST reliability
- Implemented ISO Class 5 cleanroom standards to minimize contamination risks
- Optimized bond pad structures to withstand higher Cu wire stress
The company's AuPCC wire (99.99% pure Cu core with Pd/Au coating) now dominates their production lines, while their Hybrid Cu Wire achieves AEC-Q006 compliance for mission-critical applications.
Market Leadership
"Unlike competitors limited by legacy gold wire processes, we've built our automotive IC packaging around copper from the ground up," said Dr. Wei Zeng, Winner's CTO. Their technology roadmap includes:
- 40% production cost reduction versus gold wire solutions
- 100% qualification rate in AEC-Q100 temperature cycling tests
- Expansion into 5G-enabled vehicle connectivity modules
Sustainable Advantage
With wirebond packaging maintaining 90%+ market share, Sichuan Winner's copper solutions position automakers to meet both reliability demands and EV cost reduction targets. The company expects copper wire adoption to grow 15% annually through 2028, particularly in advanced driver-assistance systems (ADAS).
