NAND Flash & Packaging Technology NAND闪存与封装技术

HICHIP's expertise spans NAND technology understanding, advanced IC packaging, firmware development, and storage module manufacturing. We bridge the gap between raw NAND wafers and market-ready products. 海芯的专业知识涵盖NAND技术理解、先进IC封装、固件开发和存储模组制造。我们架起了NAND晶圆与市场就绪产品之间的桥梁。

NAND Cell Technology Evolution NAND单元技术演进

From SLC to QLC — each generation trades endurance for density. We select the right NAND for every use case. 从SLC到QLC — 每一代都在耐久性和密度之间权衡。我们为每个用例选择最合适的NAND。

SLC

Single-Level Cell

1 bit / cell
100K P/E Cycles Fastest Read/Write Highest Endurance Industrial Primary Use
MLC

Multi-Level Cell

2 bits / cell
10K P/E Cycles Fast Read/Write High Endurance Enterprise Primary Use
TLC

Triple-Level Cell

3 bits / cell
3K P/E Cycles Good Read/Write Medium Endurance Consumer/DC Primary Use
QLC

Quad-Level Cell

4 bits / cell
1K P/E Cycles Read-Optimized Performance Highest Density Data Center Primary Use

3D NAND Layer Evolution 3D NAND层堆叠演进

Vertical stacking revolutionized NAND density. Solidigm leads with 192-layer floating gate QLC technology. 垂直堆叠彻底改变了NAND密度。Solidigm以192层浮栅QLC技术领先。

IC Packaging & Testing IC封装与测试

This is what HICHIP does. Our packaging lines transform NAND dies into reliable, market-ready storage modules. 这是海芯的核心业务。我们的封装产线将NAND芯片转化为可靠的、市场就绪的存储模组。

Wire Bonding 引线键合

Gold or copper wire interconnects between die and substrate. Cost-effective for medium-pin-count packages. 金线或铜线连接芯片与基板。对于中等引脚数封装具有成本效益。

BGA / TSOP / QFN Gold / Cu Wire 15-50μm Wire Diameter

Flip Chip 倒装焊

Direct die-to-substrate connection with solder bumps. Higher I/O density and better electrical performance. 焊球直接连接芯片与基板。更高的I/O密度和更好的电气性能。

FC-BGA / FC-CSP Solder Bump Interconnect Underfill Protection

Test & Quality 测试与质量

100% burn-in testing, functional verification, and environmental stress screening for every module. 每个模组100%老化测试、功能验证和环境应力筛选。

Burn-In (125°C) Functional Pattern Test Temperature Cycling

Note: HICHIP does NOT manufacture NAND wafers. We source NAND wafers from global suppliers (Samsung, SK hynix, Solidigm) and apply our packaging, firmware, and testing expertise to produce finished storage modules. 说明:海芯利华不制造NAND晶圆。我们从全球供应商(三星、SK海力士、Solidigm)采购NAND晶圆,并应用我们的封装、固件和测试专业知识来生产成品存储模组。
