Power Consumption Surpasses 2850W! DPC Ceramic Substrates Forge the Next-Generation AI Server Heat Dissipation Base

With the rapid iteration of generative artificial intelligence and large model technologies, global AI computing power demand is experiencing explosive growth. While AI chip performance continues to improve, power consumption thresholds are constantly being pushed higher, making ultra-high power consumption a core technical challenge for thermal management and packaging in high-end AI servers. Represented by NVIDIA's next-generation Rubin (R200) AI chip, single-chip power consumption has already surpassed 2850W, far exceeding the 2000W thermal dissipation limit of traditional HDI printed circuit boards. Conventional organic substrates centered on FR-4, due to inherent shortcomings such as insufficient thermal conductivity and poor structural stability, can no longer meet the packaging and thermal management requirements of ultra-high-power AI chips, becoming a critical bottleneck constraining the iteration of high-end computing hardware. Against this backdrop, DPC (Direct Plated Copper) ceramic substrates—featuring ultra-high thermal conductivity, excellent mechanical stability, and high-precision wiring capabilities—are emerging as the core thermal solution for addressing the 2850W-class ultra-high-power AI chip cooling challenge and enabling scalable deployment of 2.5D advanced packaging, thereby supporting stable and efficient operation of high-end AI servers. The industry is now entering a period of dual dividends from technological iteration and market expansion.

I. Bottlenecks of Traditional Organic Substrates Become Evident; New Thermal Architectures Accelerate Iteration

High-end AI chips are progressively evolving toward larger sizes, higher densities, and greater power levels, making the material limitations and process bottlenecks of traditional organic substrates increasingly pronounced. These have become major constraints on upgrading high-performance computing hardware. Thermally, FR-4 organic substrates exhibit extremely low thermal conductivity, making it difficult to rapidly dissipate concentrated heat flux generated by chips. Prolonged high-temperature operation can lead to device throttling, reduced stability, and shortened lifespan, failing to meet the thermal management demands of sustained high-compute workloads. Structurally, organic substrates suffer from insufficient rigidity and high coefficients of thermal expansion, causing warpage and deformation during large-area packaging and multi-step assembly processes. This significantly reduces chip packaging yield and assembly precision, hindering mass production scalability. In terms of manufacturing, traditional substrates have limited fine-feature processing capabilities, with inadequate via size and pitch accuracy, making them incompatible with the miniaturization and high-density wiring requirements of advanced chips and unable to meet 2.5D advanced packaging standards—thus completely losing their ability to support mass production and stable operation of 2850W ultra-high-power AI servers.

To address these industry pain points, the hybrid integration architecture combining "HDI PCB + DPC ceramic substrate" has been widely adopted as the mainstream thermal solution for high-power AI servers. This approach avoids the high cost of full-board material replacement by embedding DPC ceramic substrates only in core regions with high heat flux density and high current loads—accounting for approximately 30% of the total board area. This architecture retains the cost-effective, large-area wiring advantages of traditional HDI PCBs while leveraging ceramic materials for localized high-efficiency heat dissipation, balancing performance and manufacturing economics. Currently, this solution has been validated and commercially deployed at scale by leading global server manufacturers, representing the optimal thermal management strategy for 2850W ultra-high-power computing chips.

They have become the foundational thermal platform enabling stable operation of next-generation AI servers.

In terms of thermal performance, DPC ceramic substrates achieve a thermal conductivity of up to 200 W/(m·K)—more than two orders of magnitude higher than conventional FR-4 materials—offering exceptional heat dissipation advantages. Their coefficient of thermal expansion closely matches that of silicon chips, effectively preventing thermal mismatch, interfacial cracking, and coating delamination under high-temperature conditions. When integrated into HDI hybrid structures, the overall package thermal resistance can be reduced by over 70%, establishing a vertically efficient heat conduction pathway to rapidly channel concentrated chip heat flux and fundamentally overcoming the thermal bottleneck of 2850W ultra-high-power AI chips, ensuring sustained and stable operation of high-end AI servers.

Regarding mechanical structure, DPC ceramic substrates exhibit high rigidity, minimal deformation, and excellent flexural strength, enabling warpage control within extremely tight tolerances throughout the entire manufacturing process—including component placement, reflow soldering, and packaging tests—significantly improving packaging yield and system reliability. Additionally, these products support ultra-thin custom designs, effectively reducing overall package thickness and facilitating lightweight, miniaturized upgrades for AI servers and computing terminals, providing robust structural support for the mass commercialization of 2850W ultra-high-power AI chips.
