At Envitest Laboratories, we take pride in solving complex product qualification challenges with precision and technical expertise. One such recent milestone was the successful execution of two critical mechanical durability tests—Torsion and Bending Tests—for DDR5 SDRAM modules, strictly in accordance with the JEDEC standard JESD79-5C.01.
DDR5 SDRAM is at the core of high-performance computing, and its mechanical reliability is vital to ensure long-term functional integrity. The JEDEC JESD79-5C.01 standard defines specific stress tests to validate the mechanical endurance of memory modules under real-world handling and usage conditions. Here’s how Envitest brought this testing campaign to life:
1. Torsion Test: Simulating Mechanical Strain with Accuracy
- Test Parameters: 50,000 cycles at -1.0° to +1.0° torsion, applied at 40 degrees/second
- Objective: To assess the component’s ability to withstand repeated torsional strain without physical or functional damage.
- Standard Followed: JEDEC DDR5 SDRAM JESD79-5C.01
Envitest’s engineering team custom-configured the torsional test setup using precision servo motors, ensuring a tight control over angular motion and speed. Through high-speed data logging and inspection checkpoints, we validated mechanical fatigue resistance over all 50,000 cycles. The module withstood the test without failure—an outcome that showcases the product’s robustness and Envitest’s capability in executing such high-repetition, high-precision tests flawlessly.
2. Bending Test: Verifying Structural Integrity Under Stress
- Test Parameters: 23N force at 20 cm/min for 2 full cycles
- Objective: To test the module’s flexural strength and durability during assembly and installation conditions
- Standard Followed:JEDEC DDR5 SDRAM JESD79-5C.01
This test demanded both mechanical accuracy and real-time data monitoring. Envitest’s setup precisely applied a 23N load while controlling the rate of deflection as per standard. High-resolution displacement sensors and post-test visual inspections confirmed no visible deformation or structural damage, successfully passing the qualification requirement.
Built for Compliance. Executed for Excellence.
As a NABL-accredited test lab, Envitest ensured that all methods, equipment calibrations, and records adhered strictly to ISO/IEC 17025 standards, reinforcing the credibility and traceability of test outcomes. Both tests were internally validated for relevance and accuracy before execution, aligning with ISO 17025 Clause 7.2 requirements.
Our ability to simulate real-world conditions with precision, and tailor testing as per advanced JEDEC standards, demonstrates why leading tech innovators trust Envitest for their product qualification and reliability testing needs.
When it comes to testing where reliability cannot be compromised—Envitest delivers.
Let us help you validate your next-generation technology with confidence.
