APPLICATIONS · 应用领域

AI & Semiconductor Applications

Where every micron and every milliohm of contact resistance matters. 每一微米、每一毫欧的接触电阻都至关重要的应用场景。

🤖

AI Connector Contacts

AI连接器触点

High-bandwidth AI server connectors (PCIe 5.0, CXL, NVLink) demand ultra-thin strip at 0.05–0.08mm with tight thickness tolerances. C7035 is specified for its combination of high springback force and sufficient conductivity for multi-gigabit signal integrity.

📱

iPhone & USB-C Components

iPhone / USB-C 部件

Apple's USB-C Lightning connector and MagSafe contacts use C7035 at 0.05–0.06mm. The alloy must maintain contact force through millions of mating cycles while surviving Apple's rigorous thermal and mechanical test protocols.

AI Memory Module Leads

AI内存模组引线

Nvidia's HBM and GDDR AI memory ramp-up has created extraordinary demand for AD-442 (Dowa's proprietary designation) for memory module contact leads. High-density packaging requires ultra-thin strip with exceptional flatness and surface finish.

🔬

Semiconductor Test Sockets

半导体测试插座

IC test socket contacts require extremely high strength to maintain contact force after millions of insertions at elevated temperatures. YCuT-FX copper-titanium is the only alloy that combines the required strength (900+ MPa) with sufficient conductivity for high-frequency testing.

IC Lead Frames

IC引线框架

C19400 and C7035 for semiconductor lead frames in advanced IC packaging. High conductivity for heat dissipation, precision stamping capability for fine-pitch applications, and surface finish compatible with wire bonding and soldering.

Samsung Memory Contacts

三星内存触点

Samsung Galaxy connector contacts, display frame terminals and memory module leads. Consistent high-volume supply from Shenzhen with short lead times — critical for Samsung's just-in-time manufacturing at its Vietnam factories.

Why C7035 at 0.05mm Is a Global Scarcity · 为什么0.05mm的C7035是全球稀缺资源

Dowa (Japan) achieves C7035 at 0.05mm through their proprietary Texture Control (TC) rolling process — a technology that has not been replicated anywhere in the world, including China. The combination of ultra-thin gauge with tight thickness tolerance (±0.002mm), excellent flatness and the required mechanical properties makes this a genuine technological monopoly. Chinese domestic Corson alloy producers can reach 0.08–0.10mm but cannot achieve 0.05mm at production quality. Bobon Copper has direct sourcing relationships with Dowa and can supply C7035 at 0.05–0.06mm with full CoA documentation for Foxconn, Luxshare and connector OEM qualification programmes.

同和（日本）通过专有TC工艺实现C7035 0.05mm超薄带材，这一技术全球尚无复制，中国国内科森合金产商可达0.08–0.10mm，但无法实现0.05mm生产质量。宝邦铜业与同和有直接采购关系，可供货并附完整CoA文件，支持富士康、立讯精密等连接器OEM资质认证。
