WHY THERMAL DIGITAL TWIN

Thermal engineering is becoming a critical differentiator for next-generation HBM

As HBM moves toward higher stacks and higher power density, Thermal Engineering is becoming a product-level KPI for performance, reliability, and package design.

01 · INDUSTRY TREND

Higher Stack · Higher Power Density

  • 12-layer+ stacking and higher power density
  • Thinner dies · Warpage · Interface materials
  • A multi-physics packaging problem, not just cooling
02 · THERMAL KPI

Thermal Resistance Becomes a Product KPI

  • Public example: ~17% lower thermal resistance
  • Dedicated heat-dissipation path example: ~30% reduction
  • Thermal performance joins bandwidth and capacity as a key KPI
03 · ENGINEERING CHALLENGE

NVIDIA TECHNOLOGY ROADMAP

Scaling productization with NVIDIA accelerated computing

NVIDIA GPU and CUDA remain core acceleration technologies, while PhysicsNeMo and Omniverse/OpenUSD are evaluated progressively. For field operations, we use an x86-based Physical AI Server as the primary platform; Jetson/TensorRT is applied selectively as an edge inference node after validating application, driver, and NVIDIA SDK compatibility.

PHYSICAL AI SERVER & EDGE INFRASTRUCTURE

Industrial AI Edge Server first, with field inference where it adds value

For enterprise operations, external services, maintainability, and software compatibility, we use x86_64 servers/workstations as the primary Physical AI operating platform. NVIDIA Jetson is reserved for validated low-latency edge inference close to equipment, with ARM/JetPack and SDK constraints reviewed in advance.

INDUSTRIAL INTEGRATION

  • Edge-to-Server Architecture

Deployment principle. Jetson is not positioned as a universal server replacement. We first validate the customer's software stack and operating requirements, use x86 Physical AI Servers as the default platform, and add Jetson only where the NVIDIA ecosystem and edge workload are a clear fit. Hardware sourcing and integration do not imply NVIDIA-authorized distributor or reseller status.
