Environmental Stress Screening

Test That Ensures Reliability

Benchmark offers extensive test and environmental stress screening (ESS) capabilities to ensure long operating lifetimes for rugged electronic systems even when they are used under the harshest conditions. ESS testing requires specialized equipment and expertise but contributes to significantly increased product reliability. We bring the engineering experience needed to develop and perform a vast array of ESS processes. In addition, Benchmark has made significant investments in the test equipment and hardware, including environmental test chambers, required for ESS testing of electronic systems for critical industrial and military applications.

Benchmark’s ESS testing replicates and exceeds the temperature, humidity, shock, and vibration extremes that a production unit will face under the worst operating conditions, ensuring that it will meet its expected performance specifications even under those conditions. ESS testing includes thermal cycling screening, random vibration testing, variable humidity exposure, and shock testing to a wide range of standards or custom requirements.
