Reliability analysis

Reliability analysis

Are you unsure how the environmental factors affect the reliability and lifetime of your product? Would you like to improve reliability or competitiveness of your product and lower maintenance and warranty costs? Is your customer asking what kind of life-time does your product have? Or, did your product have unexpected failure in the field and you do not know what caused it?

Let us help! We are passionate about helping you to improve the reliability of your products.

Reliability test – test planning and tailored testing

Reliability testing without proper test definition or reliability goals is both time consuming and costly. In worst case testing may give you totally incorrect answers how your product will behave in the hands of your customers.

Determining mission profiles helps to select the critical test environments. Correctly defined reliability goals and mission profiles are the key factors for a good design and an efficient test plan.

Test methods should be optimized for each product according to the use environment and used materials. Tailored test methods are often needed, if the aim is to determine or improve reliability of your product.

We help you to consider the environmental factors affecting the reliability and lifetime of your products and to find an effective reliability test plan. This is especially important if you are planning to use new technologies or materials of which you do not have history or field data available. Reliability can be analysed either for components, sub-assemblies or complete products.

Our Reliability guide -service helps you to determine mission profiles and optimize test methods for your products!

We help you to

*Define your mission profiles, use environment and reliability metrics
*Understand better your product’s use environments and reliability requirements
*Verify the applicability of new technologies and materials
*Speed up R&D
*Optimize your reliability analysis so that you can get the most out of test

*Test methods, test tailoring, stress levels and testing time
*How to monitor samples and define failures during testing, how to interpret test results

Life-time estimation

A key part of reliability analysis is to extrapolate results of accelerated testing to real-time use. This is challenging, but to estimate the lifetimes, we offer prediction models, computer-aided reliability analysis, testing, testing data analysis and our extensive know-how gained from performing reliability tests for various industrial structures.

Computer-aided reliability analysis

In addition to actual testing, computer-aided analysis is a neat tool for reliability management and lifetime estimation. We use Sherlock Automated Design Analysis™ from DfR Solutions to analyze the reliability of your product.

With Sherlock-analysis we can easily and quickly create a 3D finite element method (FEM) model using the layout files of your design. In the analysis the effects of stresses such as thermal and mechanical shocks and vibrations can be analysed for example for solder joints, vias and components.

 

This enables

*Verification of PCB layout early in product development before prototyping phase
*Saving time and money by optimizing the product before reliability and validation tests
*Estimation of lifetime and failures

Our Sherlock™ Reliability analysis -service helps you to save time and money!

Failure analysis

Failure analysis means determining why a failure happened. Therefore, failure analysis is a crucial part of reliability testing and analysis. There are many different methods for this, depending the type of failures seen or materials used in your product.

Failure analysis is also a useful tool if unexpected failures have occurred in your product during use. With carefully selected failure analysis methods we can find out what went wrong and how you can prevent it from happening in the future.

Very often we perform failure analysis by preparing cross-sections of the failed structure. By carefully grinding and polishing the surface, we can use various microscopic techniques to study even small details of the failed structures. Scanning electron microscopy (SEM) with elemental analysis is a typical and effective analysis method.
