Will your products perform reliably once they're in your customers' hands? Will your warranty costs exceed your development costs? Consistent product reliability is essential for today's technology firms.

Reliability prediction and testing demonstration is a significant development program of ours. We use industry leading test methods and data collection for reliability models that provide an accurate estimate of warranty costs long before field data exists

To keep your project on schedule, we can design acceleration factors to fully test and prove product performance in a timely, cost-effective manner, using industry acceptable testing and statistical practices. If superior product performance is your goal, Percept's accurate and effective reliability testing will help make it a reality.

MTBF Reliability Prediction Models

Percept offers a Mean Time Between Failure (MTBF) reliability prediction analysis product that addresses needs of most customers. Upon receiving your product Bill of Material (BOM), Percept will use advanced reliability software modeling, along with real world data and our expertise, to predict a MTBF for your product. The service includes a comprehensive report & and consultation from one of our reliability experts.

Mean time between failure (MTBF) prediction has many applications including substantiating a design requirement, identifying reliability drivers, making competitive product evaluations, selecting warranty periods, advertising and marketing. Percept can help you calculate your MTBF.

Prediction using MIL-HDBK-217 or Telcordia® provides a front-end look at mean time between failure. The model can predict MTBF using as little as the part type and count information. As the design progresses it can be updated to include thermal and piece part circuit stress analysis information. MIL-HDBK-217 is useful for both military and commercial electronics.
Telcordia prediction models address commercial electronics only. It has the ability to consider the results of burn-in test, assembly and top assembly test, acceptance test, and field performance data. Hence, it can calculate pre-production, production and operational MTBF.

Percept's expertise with predictive models allows us to evaluate the failure rate and MTBF of your product and target areas for potential reliability improvement. We keep up to date with the most widely accepted reliability models in the industry, including:

MIL-HDBK-217
Telcordia®/Bellcore
SR-332
Parts Count

We perform reliability allocation calculations, derating analyses, and provide a custom designed visual report to display your results in an informative and professional style.

Accelerated Testing

Accelerated testing can be done using several industry standard techniques including:

Arrhenrius � derived from the reaction rate equation. Uses activation energy for failure mode.
Eyring � formulated from quantum mechanic principles, typically used for temperature acceleration.
TH � variation of Eyring for Temperature-Humidity
Inverse Power Law (IPL) � used for non thermal accelerated stresses (voltage, vibration, etc).
Step stress modeling

Highly Accelerated Life Testing (HALT)

Testing with HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screens) techniques have revolutionized product design, reliability and time to market. Producing results in a fraction of the time and expense of traditional stress testing, HALT subjects the product to stresses at levels well beyond those expected in normal use until the product fails. HALT testing identifies weaknesses in product design and improves product reliability.

Reliability Demonstration Testing (RDT)

Percept has in-house RDT labs that can perform RDT testing using industry accepted accelerating factors. This gives you a rapid indication of how your product will perform in the field and conform to specific reliability modeling.

Project Management

Effectively managing your testing project requires in-depth expertise to define, execute, track, communicate, and document all aspects of your testing project throughout every phase of the testing.

Percept's Test Project Management Process is a proven methodology that takes the worries out of managing the test process and ensures that your products are fully tested, proven and ready to ship around the world.
