Case Study: SATA SSD Performance Drop Analysis
Technical Inquiry
A customer reported reduced write performance after a 72-hour burn-in test on a 128GB SATA SSD and requested technical verification.
Technical Analysis
Our engineers reproduced the customer's test environment and confirmed the SSD hardware operated normally. The performance change was identified as firmware behavior under intensive write conditions.
Strategic Action
Returned samples, new production units, and comparison devices were evaluated to verify the root cause under identical test conditions.
Result & Conclusion
The investigation confirmed the performance change was firmware-related rather than a hardware defect, providing the customer with verified technical guidance for product validation.
Engineering Value
System-level validation, firmware behavior analysis, and root cause investigation for industrial storage applications.
Case Study: eMMC PCB Fanout Optimization and Validation
Technical Inquiry
A client requested confirmation on whether 'Not Connected' (NC) pins on an eMMC BGA footprint could be shorted to adjacent lines to simplify their PCB routing.
Technical Analysis
We verified that the specified NC pins are internally disconnected, confirming they can be safely used for routing without affecting device operation.
Strategic Action
During the layout review, we proactively identified a missing Data Strobe (DS) connection for HS400 performance and supplied verified samples to ensure seamless prototype testing.
Result & Conclusion
The client successfully integrated the samples into their manufacturing process, ensuring both design flexibility and optimized performance for their final application.
