Udix's advanced packaging technology: integrated process of chip bonding, wiring, and module mounting

1. Industry pain points drive technological innovation

As the semiconductor industry enters the post-Moore era, chip design becomes increasingly complex and system integration continues to improve. The traditional segmented production model of "packaging-testing-module assembly" gradually reveals numerous drawbacks. Logistics turnover between multiple links, repeated testing, and technical docking between different manufacturers not only prolong the product launch cycle but also increase quality risks and manufacturing costs.

Addressing this industry pain point, UDIC Semiconductor, leveraging its years of technical expertise in advanced packaging and testing, has innovatively introduced an integrated manufacturing process concept. The head of the company's technical team stated, "Under the traditional model, a chip needs to undergo processing by at least 5-6 different manufacturers from wafer cutting to becoming an applicable module, with the entire cycle lasting 4-6 weeks. Our integrated manufacturing process, on the other hand, centralizes all key processes within the same factory, enabling us to shorten the delivery cycle to 1-2 weeks while significantly reducing losses in intermediate links."

II. Seamless integration of three core processes

The integrated manufacturing process technology of UDChip encompasses three core aspects: chip bonding, wiring, and module assembly, achieving fully automated production from bare chips to finished products:

1. High-precision chip bonding technology

The company has mastered various technologies, including thermocompression bonding, ultrasonic bonding, and advanced flip chip bonding, capable of achieving a bonding accuracy of ±1μm. For different application scenarios, UD-Chip can provide various bonding solutions such as gold wire, copper wire, and copper pillar bumps, meeting different reliability requirements from consumer electronics to automotive electronics. Especially in automotive-grade products, the company's bonding process has passed AEC-Q100 certification, enabling stable operation in a wide temperature range from -40℃ to 125℃.

2. High-density wiring technology

The Redistribution Layer (RDL) technology, independently developed by UD-Core, enables the redistribution of I/O pads on the chip to more suitable locations, achieving higher density interconnection. The company adopts advanced copper damascene technology, which can produce fine wiring with line width/line spacing as low as 2μm, significantly improving signal transmission speed and reducing power consumption. This technology plays a key role in SiP (System-in-Package) and Chiplet heterogeneous integration, efficiently integrating chips of different process nodes and functions together.

3. Intelligent module mounting technology

In the module assembly process, Youdi Core has introduced fully automated high-precision assembly equipment and intelligent quality inspection systems. The assembly accuracy can reach ±5μm, and the assembly speed can reach up to 20,000 pieces per hour. At the same time, the company has adopted advanced machine vision and AI algorithms, which can detect and eliminate defective products in real time, ensuring the consistency of product quality. By integrating assembly, soldering, testing, and other processes, Youdi Core is able to provide customers with "plug and play" finished modules.

III. Technical Advantages and Market Value

The integrated process technology of UD-Core brings significant advantages in multiple aspects:

Efficiency improvement: By eliminating intermediate links, the product delivery cycle has been shortened by more than 60%, enabling rapid response to customers' market demands. The company promises to provide 7×24-hour technical support and 48-hour sample delivery service for domestic customers.

Cost reduction: Integrated production reduces expenses such as logistics, packaging, and repetitive testing, while simultaneously improving yield, resulting in an overall manufacturing cost reduction of 20%-30%.

Reliability enhancement: The entire production process is completed in a single factory, eliminating technical standard differences and quality risks between different manufacturers. All products undergo rigorous reliability testing, including temperature cycling, damp heat, mechanical impact, and other tests.

Customized services: UDChip is capable of providing customized services throughout the entire process, from chip selection and packaging design to module manufacturing, based on customers' specific needs. This helps customers shorten product development cycles and quickly bring their products to market.

IV. Wide range of application areas

Currently, UD-Chip's integrated manufacturing technology has been successfully applied in multiple fields:

Artificial Intelligence and Data Center: Providing high-density heterogeneous integration solutions for AI servers, achieving efficient packaging of computing cores, I/O cores, and HBM3D stacks, with a 40% performance improvement and a 35% cost reduction.

Automotive electronics: Meet AEC-Q100 automotive standard, provide packaging and module manufacturing services for in-vehicle storage, sensors, and power management chips, and support real-time computing requirements for autonomous driving.

Smart wearable devices: Provide high-reliability, low-power embedded storage packaging to ensure stable operation of devices such as smartwatches and wireless headphones.

Industrial control and new energy: Providing high-reliability semiconductor products for industrial automation equipment and new energy vehicles, capable of long-term stable operation in harsh environments.
