Reliability plays a fundamental role in customer satisfaction, with deep impacts on the safety of many products released on the market (automotive, medical, etc.).<\/p>

GESTLABS supports customers with a rigorous, scientific approach, which requires the ability to identify the stress tests and laboratory analyses suited to the specific failure mechanisms identified. Our personnel can follow the customer through all phases of a product’s life \u2014 from design to prototyping and production qualification \u2014 with the definition and execution of reliability tests. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\tThe calculation of MTBF (Mean Time Between Failures) is one of the cornerstones of reliability; its aim is to predict the defectiveness of a device during its useful life, i.e. before the wear-out period. The MTBF and the failure rate \u2014 which is the inverse of the MTBF \u2014 can be determined from experimental tests or, in the case of electronic boards, also in accordance with specific standards. The MTBF value is a fundamental requirement for the customer and is indispensable in many sectors, such as automotive, medical and aerospace. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\tThe useful life is the period during which the device performs its functions optimally, i.e. it is not yet affected by wear phenomena. This period normally extends beyond the warranty period and must match the customer’s expected service life. It is determined through accelerated stress tests or \u2014 especially in the design phase of electronic boards \u2014 through specific calculations in accordance with specific standards. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Statistical distributions (chi-squared, Weibull, exponential, etc.) are indispensable for correctly performing reliability projections from test data. Through these distributions it is possible to determine the MTTF (Mean Time To Failure) and the MTBF (Mean Time Between Failures) with the related confidence intervals based on the sample size used. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t\t\t\t\tFor reliability predictions it is often necessary to go beyond theoretical calculations and perform specific stress tests aimed at accelerating specific failure mechanisms. These accelerated tests use accelerating factors such as temperature, humidity, current, voltage, etc. It is essential to match the most appropriate accelerating factors \u2014 with adequate values \u2014 to the various failure mechanisms, to avoid triggering abnormal failure mechanisms or, conversely, using insufficient acceleration factors. Acceleration factors can be determined directly from experimental data or from dedicated models, themselves derived from experimental tests. \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

During production, it is often necessary to carry out stress tests to identify and eliminate those products (devices or materials) with defects that would only show up over time and therefore cannot be detected through normal production checks. These products, which form the \u201cweak population\u201d, can be identified through dedicated stress tests called HASS (Highly Accelerated Stress Screening), often better known \u2014 especially in the past \u2014 as \u201cburn-in\u201d. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Qualification tests are those on which the reliability estimates of the device (MTTF, MTBF, useful life) are based. They are generally accelerated tests, designed precisely to accelerate one or more failure mechanisms. It is particularly important to match qualification tests to the specific failure mechanisms the product encounters in its real application at the customer’s site. It is equally important to set test parameters so as to avoid triggering abnormal failure mechanisms or, conversely, using acceleration factors that are too low. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
