SSD Thermochemical Reliability Methodology Pre-immersion • BOM assessment • FMEA development • Baseline performance and functionality • Initial fluid analysis • Weight and dimensions • Component compatibility tests Immersion • Aging Phase: elevated temperature, powered- on idle operation • Readout Phase: Periodic functionality assessment at nominal fluid temperature • Fluid health monitoring Post Immersion • Performance characterization • Thermal validation • Fluid analysis • Weight and dimensions • SI testing • Mechanical reliability testing • Refine FMEA RPNs based on aging results Tear Down • Components material integrity • Cross-section to check PCB, traces, vias • Material residue check This methodology combines elevated-temperature aging, periodic functional verification, and fluid analysis to evaluate the thermochemical aging behavior of SSDs in single-phase immersion environments.

p5

Deployment environments and accelerated aging environments have different objectives. Why not use Deployment Environment? Deployment Environment SSD Thermochemical Reliability Testing Environment Designed to maximize system performance and cooling efficiency Designed to accelerate thermochemical aging mechanisms through controlled elevated-temperature exposure Operates near customer operating temperatures Requires elevated temperatures to accelerate thermochemical interactions and degradation mechanisms Multiple components contribute materials and contamination sources Controlled BOM simplifies assessment of materials-fluid interactions Difficult to isolate SSD-specific effects SSD-only testing enables assessment of SSD-specific thermochemical aging effects Larger volumes of fluid Smaller fluid volumes support operational ease while maintaining sufficient volume for fluid aging analysis

p6

Design Goal Develop a dedicated SSD-only immersion platform capable of supporting accelerated thermochemical reliability evaluation while reducing the cost and complexity of full-system immersion infrastructure. Resulting Design Need A dedicated SSD-only immersion platform rather than a conventional deployment tank From Testing Challenges to Design Requirements Key Requirements Support elevated temperature operation (up to ~80°C) Maintain sufficient sample size of SSDs in a powered-on state during aging Enable periodic functional and performance assessments Support fluid property and chemistry analysis Control wetted materials and contamination sources Minimize fluid volume while maintaining sample density
