Conformally Coated RDIMMs for Liquid Immersion Servers

SMART Modular introduces conformally coated RDIMMs for liquid immersion servers! This innovative product line combines the superior performance of DDR5 technology with enhanced protection, ensuring reliability and longevity in the most demanding data center environments.

The conformal coating on these DDR5 RDIMMs provides a protective barrier against environmental threats such as oxidation. This makes them particularly suited for liquid immersion cooling systems, which are gaining popularity for their efficiency and sustainability benefits.

Challenges with Standard RDIMMs in Liquid Immersion

When exposed to dielectric fluids used in liquid immersion cooling, standard RDIMMs may experience:

  • Corrosion due to changes in the physical and chemical properties of the PCB and electrical components
  • Fading of component markings, making identification difficult
  • Degradation of module labels, hindering tracking and inventory management

Key features of SMART’s Conformal Coating Process

To address these challenges, SMART Modular applies a conformal coating to DDR5 RDIMMs specifically designed for use in liquid immersion servers. This thin polymeric film conforms to the printed circuit board, providing comprehensive protection for the module’s components.

  • Applied at a thickness of 25-250μm
  • Protects against liquid, moisture, dust, and corrosive chemicals like sulfur dioxide
  • Utilizes in-house, leading-edge equipment with a fully automated spray application
  • Uses high-quality acrylic, polyurethane, silicone, and epoxy coating materials

Benefits of Conformally Coated RDIMMs

By using conformally coated DDR5 RDIMMs from SMART Modular in liquid immersion servers, data centers can:

  • Ensure long-term reliability of memory modules in liquid cooling environments
  • Maintain component and module identification for easier maintenance and tracking
  • Maximize the benefits of liquid immersion cooling without compromising memory performance

Conformally coated DDR5 RDIMMs represent a critical component in the successful implementation of liquid immersion cooling solutions, helping data centers address power and heat challenges while maintaining system reliability and performance.
